Morbihan disease (also called Morbihan syndrome, solid persistent facial edema, solid facial lymphedema, or rosacea-associated facial lymphedema) is a rare skin condition that causes chronic, firm, non-pitting swelling (edema) of the upper and middle face—especially the eyelids (periorbital tissue), forehead, glabella, nose, and cheeks. The swelling often starts on and off, then becomes constant over months to years. It can change face shape and, when eyelids are very swollen, even narrow the visual field. Pain and itch are usually mild or absent. Many, but not all, patients also have signs of rosacea (flushing, visible small vessels, papules/pustules). EyeWikiDermNet®
Morbihan disease is a rare condition—often linked to rosacea—in which the upper and middle face develop firm, non-pitting swelling and redness that gradually becomes permanent. It is thought to come from damaged or obstructed lymph vessels (the tiny drainage pipes in skin) plus chronic inflammation and mast-cell activity; biopsies often show dermal edema, dilated lymphatics, and clusters of mast cells.
Morbihan disease—also called solid persistent facial edema, solid facial lymphedema, or rosacea lymphedema—causes persistent, firm swelling (not easily indented by pressing) and erythema (redness) on the upper two-thirds of the face (eyelids/periorbital area, glabella/forehead, cheeks, nose). It can narrow the visual field by drooping, heavy lids and often severely affects self-image and quality of life. It may occur with or without classic rosacea lesions and can be unilateral or bilateral. PMCDermNet®
The best current explanation is lymphatic drainage failure from long-standing skin inflammation: lymph vessels get dilated or blocked, fluid accumulates, and the skin becomes thick and firm. Mast cells (cells that release histamine and other mediators) appear increased or overactive in many biopsies and may drive both swelling and fibrosis. On histology, doctors often see dermal edema, dilated lymphatics (highlighted by D2-40/CD31 stains), perivascular/periadnexal inflammation, and sometimes granulomas. PMC
Doctors think Morbihan disease sits on the spectrum of rosacea, with lymphatic vessel dysfunction (poor drainage of lymph fluid) playing a central role. Skin biopsy is supportive but not specific; it often shows dermal edema, dilated lymphatic channels, and sometimes clusters of mast cells. Special stains (D2-40, CD31) can highlight lymphatics. PMCJCAD
In simple words: the tiny lymph vessels under facial skin don’t drain fluid properly. Repeated inflammation (often related to rosacea) and immune cells around vessels may damage or block these lymph channels. Over time, protein-rich fluid stays in the skin, the skin becomes thicker and firmer, and the swelling becomes permanent. Histology and clinical reviews support this lymphatic-based mechanism; some studies also note mast cells and granulomatous changes that can obstruct or remodel lymphatics. DermNet®PMC
Newer imaging in selected patients (for example indocyanine green lymphography) can demonstrate abnormal facial lymph flow and “dermal backflow,” strengthening the lymphatic explanation. PMCe-acfs.org
Types
Because there is no single official classification, clinicians often group cases by patterns that matter for diagnosis and care:
Rosacea-associated type – Morbihan changes plus classic rosacea signs (flushing, telangiectasia, papules). DermNet®
Rosacea-minimal/absent type – Typical firm facial edema without obvious rosacea; this raises more differential diagnosis workup to rule out other granulomatous or inflammatory disorders that can mimic it. Brieflands
Periorbital-predominant type – Eyelids are mainly affected; can impair the visual field and be mistaken for eyelid disorders. EyeWiki
Diffuse mid-/upper-face type – Forehead, glabella, cheeks, and nose involved together. PMC
Symmetric vs. asymmetric – Most are symmetric, but asymmetry can occur. JCAD
Erythematous vs. skin-colored/violaceous – Some patients have obvious redness; others show mainly volume change with a “woody,” peau d’orange texture. DermNet®
These “types” mostly help clinicians think through look-alikes and plan testing rather than change the core diagnosis.
Causes and contributors
Important note: Morbihan disease has no single proven cause. The items below are associations, triggers, or mechanisms discussed in clinical reviews and case series. A given patient may have several of them—and sometimes none are clearly present. PMCBrieflands
Chronic rosacea inflammation – Long-standing facial inflammation can damage support tissue around lymph vessels, leading to poor drainage. DermNet®
Local lymphatic vessel dysfunction – Inherent dysregulation of lymph flow in facial skin; imaging may show backflow. PMC
Granulomatous blockage – Granulomas and histiocytes can obstruct lymphatics in the dermis. DermNet®
Mast-cell–related remodeling – Mast cells can release mediators that increase edema and may contribute to fibrosis around vessels. PMC
Repeated flushing (heat, hot drinks, emotional stress) – In rosacea, frequent vasodilation may worsen fluid leakage. DermNet®
Sun exposure – UV can aggravate rosacea and skin inflammation, fueling edema over time. DermNet®
Contact dermatitis (chronic) – Persistent allergic/irritant dermatitis can destroy connective tissue around lymphatics; patch testing sometimes helps exclude this. rcastoragev2.blob.core.windows.net
Acne/follicular inflammation – Chronic perifollicular inflammation is linked in some cases. DermNet®
Sebaceous hyperplasia/“rosacea skin” – Oil-gland changes often coexist and reflect the inflammatory milieu. rcastoragev2.blob.core.windows.net
Facial surgeries/trauma (rare antecedents) – Any event that scars lymph channels can theoretically reduce drainage. (Mechanistic inference from lymphedema literature.)
Chronic sinus/ocular surface irritation – Recurrent local inflammation near eyelids and midface can add lymphatic load. (Clinical inference aligning with periorbital predominance.)
Certain medications that flare rosacea (e.g., high-dose niacin) — may worsen flushing; not a direct cause, but a promoter. (General rosacea principle.)
Alcohol – A well-known flushing trigger in rosacea, which may perpetuate leakage. DermNet®
Hot, spicy foods – Another flushing trigger in rosacea; frequent vasodilation can aggravate edema. DermNet®
Heat or steam exposure – Sauna, hot showers can provoke facial flushing. DermNet®
Idiopathic (no clear trigger) – Some patients have no obvious driver; the disease simply evolves. JCAD
Overlap mimics (sarcoidosis, orofacial granulomatosis, lupus, scleredema, leprosy) – These conditions can look like Morbihan or coexist; ruling them out is part of the workup. Brieflandsjaadcasereports.org
Thickened dermis from long-standing edema – The longer lymph fluid stays, the more fibrosis develops, locking in swelling (a self-reinforcing cycle). PMC
Eyelid anatomy factors – The periorbital region has loose connective tissue and is prone to lymph stasis, which is why eyelids are frequently involved. (Anatomy-based clinical reasoning supported by periorbital-predominant reports.) EyeWiki
Rare pitting variants – Although Morbihan classically shows non-pitting edema, reports describe pitting in some cases, reflecting variable tissue composition. Medical Journals Sweden
Common symptoms and signs
Firm swelling of the upper face – Especially eyelids, glabella, cheeks, nose; typically non-pitting and persistent. PMC
Heaviness or tightness of the eyelids/forehead — a “weighty” feeling without much pain. EyeWiki
Redness (erythema) over swollen areas — may fluctuate or be constant. PMC
Flushing episodes — triggered by heat, alcohol, spicy food, stress. DermNet®
Visible small vessels (telangiectasia) — thin red lines across cheeks or nose. DermNet®
Papules/pustules of rosacea — present in many but not all patients. DermNet®
“Peau d’orange” texture — skin can look dimpled or “woody.” DermNet®
Morning worsening — swelling can look more pronounced after lying down. (Common lymphedema pattern; clinical inference.)
Gradual progression — intermittent swelling becomes permanent over time. PMC
Change in face shape — broader nose bridge, heavier lids, fuller midface. PMC
Visual field narrowing — heavy upper lids can partially block upward/lateral vision. EyeWiki
Minimal itch/pain — discomfort is usually mild; burning may occur during flares. PMC
Asymmetry at times — one side can swell more. JCAD
Photosensitivity aggravation — sun can flare redness and swelling. DermNet®
Psychosocial impact — appearance changes can affect self-esteem and social life. JCAD
Diagnostic tests
Diagnosis is mainly clinical (how it looks and feels) plus exclusion of look-alike diseases. Biopsy supports the story; imaging of lymph flow is sometimes used in difficult cases. Below are practical tests grouped the way a clinician might organize them, with simple explanations.
A) Physical examination
Visual mapping of swelling
The doctor inspects the distribution—upper two-thirds of the face, especially eyelids, glabella, nose, cheeks. The swelling usually looks firm and persistent. This pattern raises suspicion for Morbihan disease. PMCPalpation for “pitting” vs “non-pitting”
Pressing a thumb into the skin and watching for a dent helps judge fluid vs fibrosis. Morbihan classically is non-pitting, though rare pitting variants exist. PMCMedical Journals SwedenAssessment of erythema and flushing
The clinician notes baseline redness, visible small vessels, and asks about triggers (heat, alcohol, spicy foods). These rosacea features often travel with Morbihan. DermNet®Texture check (“peau d’orange” / woody feel)
A dimpled or thickened texture suggests chronic lymph stasis with dermal remodeling. DermNet®Eyelid measurements and visual field screening
Simple checks (e.g., margin reflex distance, confrontation fields) estimate how much eyelid swelling narrows vision and whether specialty eye testing is needed. EyeWikiPhoto documentation over time
Standardized photographs at visits help confirm progression vs stability, because changes can be slow and subtle (a practical clinical tool for all chronic facial swellings). (Clinical practice pattern supported by chronic course descriptions.) PMC
B) Manual tests and bedside tools
Diascopy (glass-slide blanching)
Pressing a clear slide on red areas tells if redness comes from dilated superficial vessels (it blanches) or deeper pigmentation. In Morbihan, erythema usually partly blanches, consistent with rosacea vessels. (Rosacea exam principle aligned with MD redness.) DermNet®Thumb-pressure edema test
A firm 10–20-second press helps feel how solid the swelling is. Morbihan often leaves little or no pit, supporting the diagnosis. PMCCircumference/tape measurements (eyelids, midface)
Simple girth measurements (or caliper distances across landmarks) create a baseline to track swelling over time or after treatment. (Common lymphedema follow-up method.)Tissue tonometry
A small spring-loaded plunger estimates tissue firmness. Firmer readings can reflect fibrosis from long-standing edema. (Adjunct method used in lymphedema programs.)
C) Laboratory & pathological tests
Skin biopsy (H&E)
A small skin sample from an involved area is checked under the microscope. Typical—but not specific—findings are dermal edema, dilated blood/lymph vessels, and perivascular/perifollicular inflammatory cells. PMCImmunohistochemistry for lymphatics and mast cells
Stains such as D2-40 and CD31 help show lymphatic dilation; special stains (e.g., toluidine blue) may reveal mast-cell clusters. These findings support Morbihan when the clinical picture fits. JCADPatch testing (allergic contact dermatitis rule-out)
Because chronic contact dermatitis can mimic or contribute to swelling, patch tests can be useful in selected patients. rcastoragev2.blob.core.windows.netAutoimmune screening (ANA ± others, if indicated)
Used to exclude connective-tissue diseases that can cause facial swelling or erythema (e.g., cutaneous lupus, dermatomyositis). BrieflandsSarcoidosis markers when suspected (ACE level, chest imaging ordered later)
Sarcoidosis can mimic Morbihan with granulomatous facial swelling; labs only support the picture and must be interpreted with clinical findings. BrieflandsGeneral labs (CBC, ESR/CRP, thyroid function) as context
These tests help rule out infection, systemic inflammation, or hypothyroid myxedema, which presents with different skin changes but can confuse the picture. (Differential-workup principle supported by review.) Brieflands
D) Electrodiagnostic & instrument-based fluid tests
These are adjuncts borrowed from lymphedema practice. They are not required for diagnosis but can quantify fluid or track changes.
Tissue Dielectric Constant (TDC) measurement
A handheld probe (e.g., MoistureMeterD) measures local skin water by assessing the dielectric constant at high frequency. Higher TDC = more tissue water. TDC is used in lymphedema research to assess localized edema and its change over time. PMC+1delfintech.comBioimpedance spectroscopy (BIS)
Safe, low electrical currents estimate fluid content. BIS is sensitive to early lymphedema in limbs and can be adapted to track facial fluid changes in specialized centers; policies and trials discuss its role and limitations. PMC+1Veterans Affairs
E) Imaging tests
Indocyanine green (ICG) lymphography
A tiny amount of fluorescent dye is injected intradermally; special cameras map superficial lymph flow. In Morbihan disease, ICG can show dermal backflow and help plan lymphatic microsurgery in selected cases. PMCe-acfs.orgLymphoscintigraphy (and, selectively, MRI/ultrasound)
Nuclear imaging of lymph drainage (lymphoscintigraphy) or soft-tissue imaging can support a diagnosis of facial lymphedema and exclude other causes of swelling. Reports include eyelid lymphedema associated with rosacea. Nature

Other agents you may see in reports: short courses of systemic steroids (often temporary benefit), azelaic acid, ivermectin (topical) for papules, and ultra-low-dose isotretinoin + antihistamines maintenance. Results vary; long-term cures are uncommon. PMC
Dietary / molecular supportive supplements
These are adjuncts to medical care. Evidence is usually indirect from rosacea/ocular-rosacea studies, not Morbihan-specific. Always review with your clinician for interactions and pregnancy safety.
Omega-3 (EPA/DHA): 1000–2000 mg/day combined EPA+DHA. Function/mechanism: anti-inflammatory; small RCTs show benefit in ocular rosacea/dry eye metrics. PMC
Probiotics (e.g., Lactobacillus/Bifidobacterium blends): follow label (often 10⁹–10¹⁰ CFU/day). Mechanism: gut-skin axis modulation; may reduce inflammatory flares in some. PMC

Non-pharmacological treatments
Key point: These measures aim to improve lymph flow, reduce triggers, and protect skin/eyes. Evidence ranges from case reports to standard lymphedema practice.
Manual lymphatic drainage (MLD) – Gentle, specialized massage that directs lymph toward functioning channels; often part of therapy plans and reported helpful as an adjunct. Purpose: reduce protein-rich fluid. Mechanism: stimulates superficial lymphatics. Oxford AcademicJCAD
Complete/Complex Decongestive Therapy (CDT) – A program combining MLD, compression, exercise, skin care; case reports in Morbihan show benefit. Purpose: comprehensive swelling control. Mechanism: augments lymph transport, prevents refilling. ResearchGate
Compression therapy (day/evening as tolerated) – Custom facial garments, taping, or gentle wraps; used alongside isotretinoin in a successful case. Mechanism: counter-pressure reduces interstitial fluid. PMC
Head-of-bed elevation – Sleep with the head elevated to reduce morning lid fullness (simple edema-hygiene principle).
Thermal trigger control – Avoid hot baths/saunas and sudden temperature shifts. Reason: heat vasodilates and worsens swelling/redness. DermNet®
Sun protection – Broad-spectrum SPF 50+, hat, shade; sun often aggravates symptoms. DermNet®
Gentle skin-care routine – Non-soap cleansers, ceramide moisturizers; avoid irritants (alcohol, strong acids). Mechanism: supports barrier, reduces neurovascular reactivity.
Avoid facial topical steroids (unless your specialist advises short, targeted use) – Steroids can worsen rosacea-like changes long-term.
Identify food/饮料 triggers – Common culprits: alcohol, spicy foods, very hot beverages. Mechanism: flush-provoking vasodilation. EyeWiki
Stress management – Breathing, CBT-style skills; stress can provoke flushing.
Structured facial exercises (within CDT) – Gentle movement helps lymph pumping. Oxford Academic
Eye care – Lubricating drops and lid hygiene if ocular surface feels dry/irritated; refer to ophthalmology if vision is affected. EyeWiki
Camouflage/medical makeup – Green-tinted primers and mineral makeup to neutralize redness; confidence support while medical therapy works.
Weight-neutral, anti-inflammatory eating pattern – Emphasize whole foods, omega-3s (see diet below).
Limit alcohol – Frequent rosacea trigger. EyeWiki
Cool packs (brief, wrapped) after heat exposure – Short vasoconstriction can ease flushing.

Drug treatments
Important: Many options are off-label; dosing must be individualized by your specialist. Treatment often requires months, sometimes 6–12+ months. Combination therapy is common.
Isotretinoin (oral retinoid)
Class: retinoid. Typical doses used in reports: 10–40 mg/day or ~0.3–0.7 mg/kg/day; some series used 40–80 mg/day for 10–24 months. Purpose: long-term reduction of inflammation/sebum; may improve lymphatic remodeling. Mechanism: regulates keratinocyte differentiation and inflammation. Notable points: Often effective alone or combined with antihistamines or antibiotics; relapses can occur; careful pregnancy prevention and lab monitoring required. Side effects: dryness, ↑lipids, teratogenicity, mood changes (rare), liver effects. PMCJCADJAMA NetworkDoxycycline (tetracycline antibiotic, anti-inflammatory dosing)
Dose used: 100–200 mg/day (or slow-release 40 mg/day) for several months. Purpose: anti-inflammatory (MMP and cytokine modulation) more than antibacterial. Side effects: photosensitivity, GI upset, esophagitis. Often combined with a short steroid taper early on. Medical JournalsPubMedMinocycline
Dose used: 50–100 mg/day for months. Purpose: similar to doxycycline; individual responses vary. Side effects: dizziness, pigment changes, drug-induced lupus (rare). ResearchGateAntihistamines (e.g., ketotifen 1 mg twice daily; desloratadine 5 mg daily)
Purpose: stabilize mast cells/reduce histamine-driven edema; frequently added to isotretinoin with good responses in small series. Side effects: sedation (older agents), dry mouth. JCADSystemic corticosteroids (e.g., prednisolone short taper)
Use: short course for flares or to “bridge” to slower medicines; not a long-term solution. Example report: prednisolone 20 mg/day × 2 weeks + doxycycline 200 mg/day × 12 weeks improved edema/erythema. Risks: weight gain, glucose/BP, mood, bone loss (long-term). PubMedMedical JournalsIntralesional triamcinolone (office injections)
Use: targeted reduction of thick, swollen eyelid tissue, often combined with debulking surgery to improve outcomes. Risks: skin atrophy if overused. PMCClofazimine (immunomodulatory antibiotic, off-label)
Dose reported: ~100 mg/day in some reports; sometimes combined with isotretinoin. Purpose: anti-inflammatory effects in granulomatous disease. Cautions: brown-red skin discoloration, GI effects, QT risk; specialist use only. PubMedTopical rosacea therapies (adjuncts): metronidazole 0.75–1%, azelaic acid 15%, ivermectin 1%
Purpose: control papules/pustules & background inflammation that may feed lymphedema. Side effects: local sting/irritation. (Adjunctive; rarely sufficient alone for Morbihan.) e-acfs.orgDapsone (oral, immunomodulatory)
Emerging option: a 2024 case reported good control in refractory Morbihan. Monitoring: G6PD status, CBC (hemolysis risk), methemoglobinemia. Dose: individualized by specialist (commonly 50–100 mg/day in other dermatoses). Frontiers Publishing PartnershipsBiologic/targeted agents in selected refractory cases
Omalizumab (anti-IgE)—monthly injections helped refractory cases, including an adolescent; suggests mast-cell involvement in some patients. Side effects: injection reactions, rare anaphylaxis. Medical JournalsPubMed
Treatment strategy tip: Reviews suggest longer courses (≥6–12 months) of systemic therapy improve durability; combining isotretinoin with antihistamines or with short steroid tapers can help difficult cases. Manual lymph drainage/compression are useful add-ons throughout. PMCJCAD
“Advanced/immune-targeting” options
These are not standard but have case-level evidence in persistent disease. Discuss risks/benefits with a specialist.
Omalizumab (anti-IgE) – monthly subcutaneous therapy; two reports (adult and adolescent) showed marked improvement. Mechanism: blocks IgE-mediated mast-cell activation. Medical JournalsPubMed
Tofacitinib (oral JAK 1/3 inhibitor) – two-patient case series reported rapid improvement. Mechanism: dampens cytokine signaling (JAK-STAT). Risks: infections, lipids, thrombosis (boxed warnings). Frontiers
Baricitinib (oral JAK 1/2 inhibitor) – 2024 case report showed benefit after years of refractory disease. Risks: similar class warnings. PubMed
Abrocitinib (oral JAK1 inhibitor) – 2025 case series improved solid facial edema (closely related phenotype). Status: promising but very preliminary for Morbihan. PMC
Tripterygium wilfordii (herbal immunosuppressant) – single case success; toxicity risks are significant (hepatic, reproductive), so specialist oversight is essential. PubMed
Clofazimine – noted above; included here for its immune-modulating properties in granulomatous disease variants. PubMed
Surgical options
Consider surgery when medical therapy fails and swelling blocks vision or severely affects daily life. Recurrence can happen; combining with medical therapy and/or steroid injections may improve results.
Eyelid debulking / reduction blepharoplasty
Procedure: excision of redundant edematous eyelid tissue; may add intralesional triamcinolone. Why: relieve heaviness, restore visual field, improve contour. Outcome: multiple small series show benefit, though recurrence can occur. PMCCO₂ laser blepharoplasty
Procedure: uses CO₂ laser for cutting/coagulation during blepharoplasty; heat may seal incompetent lymphatics. Why: reduce bleeding; potentially lower recurrence (data limited). Evidence: case series with good short-term outcomes. PubMedSurgical debulking of involved facial tissue (beyond lids)
Procedure: careful excision of thickened, edematous tissue. Why: contour restoration when localized masses form. Note: recurrence reported; histology (fewer mast cells) may predict better outcomes. PMCLymphaticovenular anastomosis (LVA, “supermicrosurgery”)
Procedure: connect tiny lymphatic vessels to nearby venules to bypass blockages and drain lymph. Why: for refractory periorbital lymphedema. Evidence: recent case reports show improvement; may be done under local anesthesia. PMCe-acfs.orgNodal-venous (lymph-node–vein) bypass
Procedure: shunts outflow from preauricular lymph nodes to a facial vein. Why: further increases lymph drainage options when LVA alone is insufficient. e-acfs.org
Dietary & supplemental supports
Safety first: Avoid vitamin A supplements while on isotretinoin. Check interactions (e.g., anticoagulants) before starting any supplement.
Omega-3 (EPA/DHA 1–2 g/day) – anti-inflammatory; may reduce skin redness/tenderness in inflammatory dermatoses.
Probiotics (≥1–10 billion CFU/day) – gut-skin axis support; some rosacea patients report calmer skin.
Vitamin D (replete if low; typical 1000–2000 IU/day) – immune modulation; check levels first.
Niacinamide (vitamin B3 amide, 250–500 mg/day) – barrier/anti-inflammatory effects; less flushing than niacin.
Zinc (15–30 mg/day) – anti-inflammatory; avoid long-term high doses (copper depletion).
Quercetin (250–500 mg/day) – mast-cell stabilizer/antioxidant.
Bromelain (250–500 mg/day) – proteolytic enzyme with anti-edema properties; caution with anticoagulants.
Diosmin/hesperidin (venotonic per label) – supports microvascular tone; sometimes used for edema disorders.
Horse-chestnut seed extract (aescin 50–100 mg/day) – venotonic/anti-edema; avoid in kidney disease/pregnancy.
Centella asiatica (60–120 mg/day standardized) – supports microcirculation/connective tissue.
Pycnogenol (50–100 mg/day) – microvascular/antioxidant support.
Green tea extract (per label; or brewed tea) – polyphenols with anti-inflammatory effects.
Resveratrol (100–250 mg/day) – antioxidant; theoretical vascular benefits.
Curcumin (500–1000 mg/day with piperine) – anti-inflammatory; drug interactions possible.
Magnesium glycinate (100–200 mg at night) – supports sleep/stress regulation; indirectly helps trigger control.
(These are supportive only; none are proven treatments for Morbihan.)
Prevention
Daily high-SPF, broad-spectrum sunscreen on face/eyelids (if tolerated). DermNet®
Heat hygiene: avoid saunas/hot tubs; cool the face after exertion. DermNet®
Trigger-aware eating: limit alcohol, spicy foods, and very hot drinks. EyeWiki
Gentle products only: fragrance-free cleanser, bland moisturizer.
Treat rosacea early and consistently to reduce inflammatory drive. e-acfs.org
Don’t rub the face/eyes; mechanical irritation can worsen swelling.
Sleep with head elevated to reduce morning edema.
Plan outdoor time (shade, hat) to minimize sun exposure. DermNet®
Keep follow-ups—this is a chronic, relapsing condition; plans often need tuning. PMC
Manage stress (breathing, CBT apps); stress can trigger flushing.
When to see a doctor
Urgently if swelling suddenly worsens, there’s pain, fever, a new vision change, or swelling becomes one-sided and tender (could be an infection or another diagnosis).
Soon (days–weeks) if swelling is persistent >2–3 weeks, there’s eyelid heaviness or narrowed vision, or rosacea is flaring despite over-the-counter care.
Regularly with dermatology (and ophthalmology if eyelids/vision are involved). This condition often needs months of consistent care and sometimes surgery for best results. PMC
What to eat & what to avoid
Focus on
Cold or room-temperature water/tea;
Omega-3-rich fish (salmon, sardines) or plant omega-3s;
High-fiber fruits/vegetables;
Whole grains;
Lean proteins;
Fermented foods (yogurt/kefir if tolerated) for the microbiome;
Polyphenol-rich foods (berries, olive oil, cocoa nibs);
Hydration through the day;
Low-salt seasoning to reduce fluid retention;
Consistent meals to avoid hot, spicy “grab-and-go” triggers.
Try to limit/avoid
Alcohol (wine/spirits commonly flush-provoking);
Spicy chilies/peppers;
Very hot beverages (let them cool);
High-salt, ultra-processed foods;
Energy drinks/vasodilating shots;
Frequent sugar spikes;
Food dyes/fragrances if you’re sensitive;
Very large evening meals (can worsen morning swelling);
Hard rubbing while eating with hands (mechanical irritation);
Vitamin A supplements if you’re on or considering isotretinoin (safety). EyeWiki
FAQs
1) Is Morbihan the same as rosacea?
Not exactly. Many patients have rosacea features, but Morbihan is the persistent, solid lymphedema form that can occur with or without classic rosacea. PMC
2) Does it go away on its own?
Usually no. It tends to persist without directed therapy. PMC
3) What’s the single most effective medicine?
Isotretinoin has the most accumulated supportive reports, often over 6–12+ months, sometimes combined with antihistamines or antibiotics. PMC+1
4) How long do I need treatment?
Expect months. Longer courses often give better, more durable results. PMC
5) Are steroids safe here?
Short systemic courses can calm flares or serve as a bridge; long-term steroids are avoided due to side effects and limited durability. Intralesional steroid shots can be useful for localized thickening. Medical JournalsPMC
6) Do antihistamines help?
They can, especially ketotifen or desloratadine as add-ons to isotretinoin in small series. JCAD
7) When is surgery considered?
If swelling blocks vision or quality of life remains poor after adequate medical therapy. Options include blepharoplasty/debulking, CO₂ laser blepharoplasty, or lymphatic bypass (LVA). PMC
8) Will it come back after surgery?
Recurrence can happen. Combining surgery with injections/medical therapy may reduce this risk. PMC
9) Can physical therapy help?
Yes—MLD and CDT can reduce swelling and support maintenance. Oxford Academic
10) Are there any “new” medicines?
Early reports show benefit with omalizumab (anti-IgE) and JAK inhibitors (tofacitinib/baricitinib), but these are experimental. Medical JournalsFrontiers
11) Is it dangerous to my eyes?
The disease itself affects eyelids/skin, but severe lid edema can narrow your field of vision; an eye doctor should check vision when lids are heavy. EyeWiki
12) Can infections cause this?
Not typically. Doctors will exclude infections and other diseases that can mimic the look before confirming Morbihan. PMC
13) Do diuretics help?
Generally not helpful—this is lymphatic, not simple water retention. (They aren’t part of standard reports.)
14) Is it common in darker skin?
Likely under-recognized rather than truly rare in darker skin; cases in skin of color are reported. Next Steps in Dermatology
15) What’s the realistic goal?
Control, not cure: reduce swelling/redness, protect vision, and maintain function/appearance with a mix of lifestyle, long-term medicines, and—if needed—procedures. PMC
