Aquagenic syringeal acrokeratoderma (ASA) is a rare skin condition. After a few minutes of touching water, small white, puffy, flat-topped bumps and soggy plaques suddenly appear on the palms (and sometimes soles). They often sting, burn, itch, or feel tight, and usually fade within minutes after drying. Doctors also call it aquagenic keratoderma or aquagenic wrinkling of the palms because the skin looks wrinkled and swollen right after water contact. ASA can happen by itself or together with other problems. It is strongly linked with cystic fibrosis (CF) and carriers of CF gene changes; it may also be triggered by certain medicines. Treatments are mostly based on small studies or case reports. Options include aluminium-salt antiperspirants, keratolytics (urea or salicylic acid), anticholinergics (like glycopyrronium), botulinum toxin, iontophoresis, and, rarely, surgery for sweat-nerve control. PMC+3PMC+3DermNet®+3
Many experts think water quickly enters the outer skin where the sweat ducts open. If the sweat is salty or the ducts are abnormal, water is pulled in even faster, which makes the skin swell and wrinkle. People with cystic fibrosis have very salty sweat and more water loss through skin, so ASA is common in them. Drugs that change salt handling in skin (for example, some NSAIDs or antibiotics) can also trigger ASA in some people. The exact cause can differ between patients, and several mechanisms may combine. PMC+2JAMA Network+2
Aquagenic syringeal acrokeratoderma (ASA) is a rare skin condition. After the hands (and sometimes the soles) touch water for a short time, small white, translucent bumps appear. The skin wrinkles more than normal, looks puffy, and the pores of the sweat glands look bigger. People often feel burning, tightness, itch, or pain. The changes usually fade after the skin dries. Doctors think the problem starts in the sweat-gland ducts and the top skin layer (stratum corneum). The condition is closely linked to how salt and water move in the skin, and it is often associated with cystic fibrosis (CF) or being a CF carrier. JAAD+2PMC+2
Why it happens
Water soaks into the top skin layer. In ASA, because of salt and water balance issues and sweat-duct changes, the stratum corneum swells quickly and wrinkling appears fast. In cystic fibrosis, abnormally salty sweat and CFTR-related water transport changes likely pull more water into the outer skin and around the sweat-duct openings. Under the dermoscope (a skin magnifier), doctors can see enlarged eccrine pores and special surface patterns like the “wood-bark sign.” Under the microscope (biopsy), common findings include hyperkeratosis (thick stratum corneum) and dilated sweat-duct openings. Non-invasive imaging (like reflectance confocal microscopy or optical coherence tomography) can also show sweat-duct and surface changes. PubMed+4JAMA Network+4PMC+4
ASA has several look-alike names in the medical literature. Some authors call it “aquagenic wrinkling of the palms” when the main change is quick wrinkling. Others use “transient reactive papulotranslucent acrokeratoderma,” “aquagenic palmoplantar keratoderma,” or simply “aquagenic keratoderma.” All of these labels describe the same pattern: water exposure triggers short-lived papules and wrinkling, most often on the palms. JAAD+2Oxford Academic+2
Other names
Doctors may use any of these names in reports or textbooks. They all point to the same core problem.
Aquagenic wrinkling of the palms (AWP) — emphasizes the fast, strong wrinkling after brief water contact. PMC
Transient reactive papulotranslucent acrokeratoderma (TRPA) — highlights the temporary, translucent bumps that appear with water and then fade. PubMed+1
Aquagenic palmoplantar keratoderma (APPK) / aquagenic acrokeratoderma — focuses on thickening/keratoderma on palms (and rarely soles) that is triggered by water. PMC
Aquagenic syringeal acrokeratoderma (ASA) — underlines changes around the “syringeal” (eccrine sweat-duct) openings. JAAD
ASA is a water-triggered skin reaction on the hands (and sometimes the feet). Within minutes of touching water, whitish, flat-topped bumps and excess wrinkling appear. The sweat-pore openings look larger. People may feel tightness, burning, itch, or pain. After the skin dries, these changes usually go away on their own. ASA is thought to come from abnormal handling of salt and water in the outer skin and functional changes in sweat-gland ducts. It is more common in females and is strongly linked to cystic fibrosis or carrying a CF gene change. JAAD+2PMC+2
Types
It helps to sort ASA into types so plans and expectations are clearer:
By cause
Primary/idiopathic ASA — no clear trigger or disease is found. The skin still reacts to water with papules and wrinkling. Lippincott Journals
Secondary ASA — occurs with another factor, most often cystic fibrosis or CF carrier status, or certain drugs (e.g., some NSAIDs or COX-2 inhibitors). JAMA Network+1
By body area
Palms only — the classic and most common pattern.
Palms and soles — less common; soles can be involved in some patients. Lippincott Journals
By frequency
Intermittent — flares with water and settles quickly after drying.
Persistent tendency — frequent episodes with daily activities involving water. PMC
By symptoms
Wrinkling-dominant — wrinkling is main feature; little discomfort.
Pain/itch-dominant — burning pain, sting, or itch with visible bumps. skin.dermsquared.com
By link to CFTR function
CF/CF-carrier associated — higher rates of AWP/ASA, sometimes improving with CFTR-modulator therapy (e.g., ivacaftor).
Non-CF ASA — same skin picture but without CFTR mutation. cysticfibrosisjournal.com+1
Causes
Cystic fibrosis (CF) — ASA/AWP is common in people with CF. The sweat is very salty and water handling in the skin is altered, making quick wrinkling and papules after water contact. JAMA Network+1
Carrier of a CF gene (CFTR heterozygote) — even one CFTR change can increase risk. Many carriers show rapid aquagenic wrinkling. PMC+1
COX-2 inhibitor drugs (e.g., celecoxib/rofecoxib class) — reported cases link these medicines to TRPA/ASA, probably by affecting sweat-gland or skin-barrier function. PubMed
Other NSAIDs — some non-steroidal anti-inflammatories have been linked to aquagenic wrinkling in case reports; stopping the drug may help. PMC
Hyperhidrosis (excess sweating) — more sweat and salt on the surface may draw water into skin faster and enlarge pores. JAAD
Sympathetic over-activity of sweat glands — suggested by good response to anticholinergic treatments (e.g., glycopyrronium). ResearchGate
Aquaporin-5 and water-channel changes — altered water channels in sweat glands have been described in AWP. DermNet®
Adolescence and young adult female sex — ASA often starts in teens/young adults and is more frequent in females, likely due to sweat/lipid and barrier differences. Lippincott Journals+1
Frequent water exposure (occupational/household) — repeated wet-work makes flares more common by constant swelling/drying cycles. PMC
High salt at skin surface — any setting that raises salt on the skin (e.g., CF) favors quick water uptake and wrinkling. JAMA Network
Topical products that impair barrier — harsh soaps or solvents can thin the lipid layer and speed water entry, revealing underlying ASA tendency. (General mechanism inferred from barrier science within AWP reports.) PMC
Heat and humidity — warm, humid conditions increase sweating and can worsen symptoms. PMC
Genetic background (non-CF) — some people without CF have idiopathic ASA, suggesting other genetic or barrier factors. Lippincott Journals
Atopy/eczema background — occasionally reported alongside ASA; barrier fragility may play a role (association noted in reviews). PMC
Certain antibiotics (e.g., reported with tobramycin in CF care) — proposed triggers in scattered reports; mechanism unclear. PMC
Salazopyrin + indomethacin combination — case reports of drug-associated aquagenic wrinkling. DermNet®
Minocycline/other medications — individual case links exist; individual de-challenge (stopping) may improve signs. DermNet®
Autonomic sweat-nerve dysfunction — sudomotor testing literature suggests sweat-gland nerve issues can change sweating; some ASA cases may overlap. (Supportive physiology from sudomotor reviews.) PubMed+1
COVID-era reporting increase — recent literature reviews note post-2014 case growth; whether COVID-19 itself causes ASA is unclear, but more cases were reported. PubMed+1
Unknown causes — many patients have no clear trigger; they fit idiopathic ASA. Lippincott Journals
Symptoms
Fast wrinkling after water — appears within 2–7 minutes, much quicker than normal wrinkling. DermNet®
White, translucent bumps — flat-topped papules that merge into plaques. JAAD
Puffy, swollen look — the wet stratum corneum swells, giving a plump surface. PMC
Visible sweat-pore dots — eccrine openings look bigger or more numerous. PMC
Burning or stinging — many patients feel a mild burn when the skin is wet. skin.dermsquared.com
Itching — itch can accompany the papules during immersion. Lippincott Journals
Tightness — skin feels tight or “shrunken” while wet. PMC
Pain or tenderness — fingertip pain is reported in some cases. skin.dermsquared.com
Peeling after episodes — mild desquamation can follow repeated flares. PMC
Soggy/soft feeling — the top layer feels water-logged. PMC
Hyperhidrosis — some patients sweat more, and this worsens flares. JAAD
Symmetric on both palms — common pattern, though unilateral cases exist. PMC
Occasional sole involvement — less common but possible. Lippincott Journals
Short duration — changes usually fade within 10–60 minutes after drying. DermNet®
Daily-life impact — discomfort with washing, bathing, or wet-work tasks. PMC
Diagnostic tests
A) Physical examination
Bedside inspection before and after water
Doctor looks at the dry hands, then again after brief water contact. The quick appearance of white papules and strong wrinkling after immersion supports ASA. PMCTimed water-immersion (“hand-in-the-bucket”) test
Hands are immersed (often 3–7 minutes). A positive test shows translucent papules, wrinkling, and prominent eccrine pores. Photos may be taken for comparison. PMC+1Distribution mapping
The doctor notes symmetry, palm vs. sole involvement, and fingertip prominence. Symmetric palmar disease is typical; soles may be involved in a minority. Lippincott JournalsSymptom provocation and recovery timing
Clinician records how fast signs appear with water and how long they take to fade after drying (often within an hour). This pattern differentiates ASA from chronic keratodermas. DermNet®Dermoscopy (hand-held skin scope)
Under magnification, doctors may see enlarged sweat-duct pores and special surface patterns such as the “wood-bark sign.” This supports a sweat-duct-centered process. PMC+1Differential diagnosis review
Doctor rules out similar conditions (e.g., hereditary papulotranslucent acrokeratoderma, aquagenic urticaria), which have different timing and appearance. DermNet®
B) Manual/office tests
Standardized temperature and timing in immersion test
Keeping water lukewarm and timing the test improves reliability and comparison over visits. This makes serial assessment more accurate. Open Access LMUStarch–iodine (Minor’s) test for sweat
Iodine is painted and starch is dusted; areas that sweat more turn dark. Many ASA patients also have focal hyperhidrosis, which this test can reveal. JAADBarrier-protection challenge
Using petrolatum or barrier cream before immersion to see if wrinkling lessens can suggest a surface-barrier role (a practical clinic check reported in reviews). PMCGlove occlusion trial
Short periods of glove use during wet tasks can reduce water contact; improvement supports a water-triggered mechanism. PMCTherapeutic trial as a diagnostic aid
Improvement with aluminum chloride, topical anticholinergics (e.g., glycopyrronium), iontophoresis, or botulinum toxin supports eccrine involvement. ScienceDirect+2ResearchGate+2
C) Laboratory & pathological tests
Sweat chloride test
A standard test for cystic fibrosis. High levels suggest CF, which is strongly linked to aquagenic wrinkling/ASA. JAMA Network+1CFTR genetic testing
Checks for mutations in the CFTR gene. Useful when ASA is the first clue to CF or when family history suggests carrier status. PMCMedication review (pharmacovigilance approach)
Systematic review of drugs (especially COX-2 inhibitors and some NSAIDs) and trial withdrawal if appropriate may identify a trigger. PubMed+1Skin punch biopsy (H&E, PAS stains)
Histology often shows hyperkeratosis and dilated eccrine ostia/ducts, supporting a sweat-duct process. Biopsy is not always needed but can confirm the diagnosis. PubMedBasic labs when indicated
Most patients need no routine blood tests. If a systemic link is suspected, CF-related evaluations are prioritized rather than general labs. (Guided by AWP/ASA reviews.) PMC
D) Electrodiagnostic sudomotor tests
QSART (Quantitative Sudomotor Axon Reflex Test)
Measures sweat output after gentle electrical stimulation. Not required for most ASA cases, but it can document sweat-gland nerve function when autonomic involvement is suspected. Cleveland Clinic+1Electrochemical skin conductance / sympathetic skin response
Non-invasive tests of sweating used in autonomic labs; rarely needed but may support sudomotor dysfunction in complex cases. PMC
E) Imaging-based skin tools
Reflectance confocal microscopy (RCM)
A “virtual biopsy” that shows sweat-duct and surface changes in vivo. Helpful when avoiding biopsy or tracking changes over time. PubMed+1Optical coherence tomography (including line-field OCT)
High-resolution imaging that can show surface ridges and duct changes during aquagenic wrinkling, supporting the diagnosis without cutting the skin. Wiley Online Library

Immunity-Booster / Regenerative / Stem-Cell” Drugs
ASA is a skin barrier/sweat-duct phenomenon. There are no proven immune-booster, regenerative, or stem-cell drugs for ASA. Below are six categories often asked about; none are established for ASA, and they should not be used for this purpose outside of clinical trials.
Systemic corticosteroids
Dose: not indicated. Function/Mechanism: broad immunosuppression; no evidence for ASA. Risks outweigh benefits. PMCBiologic immunomodulators (e.g., dupilumab)
Dose: not indicated for ASA. Function/Mechanism: targeted immune pathways; no ASA data. PMCStem-cell therapies
Dose: none. Function/Mechanism: theoretical regeneration; no role in ASA. PMCPlatelet-rich plasma (PRP)
Dose: none for ASA. Function/Mechanism: growth factors; no evidence for water-induced wrinkling disorders. PMCSystemic “immune boosters” (herbal mixes)
Dose: not recommended. Function/Mechanism: unproven; may interact with medicines. PMCSystemic retinoids
Dose: not standard for ASA. Function/Mechanism: keratinization control; insufficient evidence and potential adverse effects. PMC
Surgeries (Why and When)
Endoscopic Thoracic Sympathectomy (ETS)

Some reports show permanent ASA control when sweating is stopped. Risks: compensatory sweating, surgical risks. Indian J Dermatology+1Sweat-gland–focused procedures (rare/experimental)
Procedure: targeted treatments aimed at sweat output (e.g., energy-based). Why: considered only in research settings. Risks: scarring, nerve irritation. grimalt.netBotulinum toxin injections (procedure-based, minimally invasive)
Procedure: grid injections into palms in clinic. Why: strong non-surgical option when topicals fail. Risks: transient weakness, pain. Lippincott JournalsIontophoresis in clinic (device procedure)
Procedure: supervised sessions, then home unit. Why: reduce sweating non-invasively. Risks: skin dryness, irritation. skin.dermsquared.comBiopsy (diagnostic, not therapeutic)
Procedure: small skin sample if diagnosis is unsure. Why: rule out other palmoplantar keratodermas. Risks: small scar. Lippincott Journals
Preventions
Plan short water contact; dry quickly. PMC
Use cool water when possible. PMC
Apply petrolatum or aluminium-based antiperspirant before wet work. PMC
Wear cotton liners under waterproof gloves. PMC
Keep a simple emollient by every sink. PMC
Avoid known trigger medicines when safe/approved. PMC
Cool rooms, fans, breaks to limit sweating. Indian J Dermatology
Prefer gentle cleansers; avoid harsh soaps. PMC
Document flares with photos for pattern spotting. PMC
Seek CF evaluation if symptoms/history suggest risk. PMC
When to See a Doctor
See a clinician if: the hand pain, burning, itching, or tightness is frequent or limits daily tasks; bumps last long after drying; there is heavy sweating, cough or GI symptoms suggesting CF; you started a new medicine before symptoms; home steps do not help; or you have job-related water exposure and need accommodations. A dermatologist can confirm the diagnosis (often clinically), consider CF assessment, review medicines, and tailor a safe treatment plan. PMC+1
What to Eat & What to Avoid
What to eat: a balanced diet with enough protein and healthy fats to support skin barrier (fish, eggs, legumes, nuts), fruits/vegetables rich in antioxidants, and adequate fluids—especially in heat—to keep sweating comfortable. What to avoid: extreme dehydration or excessive caffeine that can spike sweat in some people; very spicy foods if they trigger sweating; and any supplement or herb that interacts with your medicines. These tips support comfort but do not cure ASA. PMC
Frequently Asked Questions
Is ASA dangerous?
No. It is uncomfortable but not life-threatening. The main concern is its link to cystic fibrosis or CF carrier state in many patients, so evaluation matters. PMC+1How is it diagnosed?
Usually by history and exam after brief water exposure (“hand-in-bucket” sign). Dermoscopy and sometimes Wood’s lamp can help; biopsy is rarely needed. JAMA Network+2Lippincott Journals+2How common is it in cystic fibrosis?
Reports suggest very high rates in CF and increased rates in carriers. This is why doctors think about CF when ASA appears. PMC+1What medicines can cause ASA?
Case reports link celecoxib, rofecoxib, aspirin, tobramycin, and occasionally others like clarithromycin or ACE inhibitors. Stopping the trigger can help. PMC+2ResearchGate+2Why does water do this?
Water rushes into the outer skin, especially around sweat ducts; saltier sweat or duct changes pull in more water, making white, puffy plaques. PMCDoes it happen only on palms?
Mostly palms; sometimes soles, rarely other sites. PMCWhat is the first treatment to try?
Topical aluminium chloride at night on completely dry skin is often first. Add emollients and smart water exposure control. PMCWhat if aluminium burns my skin?
Use lower strengths, apply to dry skin, reduce frequency, or switch to other options like urea/salicylic creams or topical glycopyrronium with clinician advice. Lippincott Journals+1Is botulinum toxin safe for hands?
It can help a lot, but injections may hurt and cause temporary weakness. Effects last months and then wear off. Lippincott JournalsWill iontophoresis help?
Yes, for some people. It is a low-risk device that reduces sweating and can lessen flares; it needs a schedule. skin.dermsquared.comDo I need surgery?
Almost never. ETS is only for severe, disabling cases tied to hyperhidrosis after all other treatments fail. Indian J DermatologyCan children have ASA?
Yes; it has been reported in children, especially with CF. Pediatric evaluation is important. PMCHow long do lesions last after water?
Usually minutes to tens of minutes after drying, but it varies. jaadcasereports.orgCan ASA be cured?
There is no universal cure. Many people manage it well with antiperspirants, keratolytics, anticholinergics, and procedural options. PMCWhat research is new?
Recent reviews (2014–2025) discuss updated case counts, CF links, diagnostic aids, and responses to glycopyrronium and other therapies. PubMed+1
