Melasma

Melasma is a common skin condition where brown or gray-brown patches appear, mainly on the face. Many people call it the “mask of pregnancy” because it can pop up in pregnant women. But anyone can get melasma. Melasma is caused by the overproduction of pigment in the skin called melanin. Think of melanin as the color (or tint) of your skin. When your skin produces too much of it in certain areas, you end up with those brown patches.

Types

Types of melasma in plain and simple language, helping you grasp the key details without any confusion.

1. Epidermal Melasma: Unveiling the Superficial Pigmentation

Epidermal melasma is like a top layer of paint on your skin. It occurs when the extra pigment (color) in your skin settles just beneath the outermost layer. This type is often characterized by dark patches that are well-defined and distinct. They might look like someone placed patches of darker skin on your face.

2. Dermal Melasma: Exploring Deeper Pigmentation

Think of dermal melasma as a layer of tint beneath your skin. Instead of staying near the surface like epidermal melasma, dermal melasma dives a bit deeper. The patches in dermal melasma are usually lighter and less defined compared to the epidermal type. They might appear more like a faint shadow than a distinct patch.

3. Mixed Melasma: When Epidermal and Dermal Team Up

Mixed melasma is like a blend of both epidermal and dermal types. It’s like having a layer of tint on the surface (epidermal) while another layer hides below (dermal). This type often presents with patches that have a mix of darker and lighter areas, creating a somewhat uneven appearance.

4. Sun-Exposed Melasma: Sunlight as a Trigger

Sun-exposed melasma is a type that owes its origins to the sun’s powerful rays. If you’ve spent a lot of time under the sun without proper protection, you might notice these patches. They tend to show up on areas that get the most sun exposure, like your cheeks, forehead, and nose.

5. Hormonal Melasma: The Influence of Hormone Havoc

Hormonal melasma is like a skin response to the hormonal roller coaster in your body. Pregnancy, birth control pills, and hormone therapies can all play a role. These patches often appear on the upper lip, cheeks, and forehead. Hormonal changes can make your skin more sensitive to sunlight, triggering melasma in the process.

6. Frictional Melasma: Where Rubbing Meets Discoloration

Imagine frictional melasma as a result of constant skin friction. This type can occur when something regularly rubs against your skin, like a backpack strap or even a smartphone. These patches usually pop up on the sides of your face and temples.

7. Post-Inflammatory Hyperpigmentation (PIH): After the Battle

PIH is like a souvenir from a skin injury or inflammation. It’s not exactly melasma, but it shares some similarities. When your skin goes through trauma, like acne or a cut, it might produce extra pigment in the healing process. This can lead to patches that look a bit like melasma.

8. Drug-Induced Melasma: Medications and More

Certain medications, like antimalarial drugs and some antibiotics, can lead to melasma-like patches as a side effect. If you’ve recently started a new medication and notice unusual patches on your skin, it might be a good idea to consult your healthcare provider.

9. Genetic Melasma: Inherited Possibilities

Genetic melasma is like a family legacy for your skin. If others in your family have experienced melasma, you might be more prone to developing it too. While it’s not a guarantee, genetics can play a role in making you more susceptible.

Causes

Causes explained in plain English. This guide will enhance your understanding and help those searching for reasons behind their skin discoloration.

1. Sun Exposure: The sun’s UV rays stimulate melanocytes – the cells that produce color in our skin. Too much sun can overstimulate these cells, causing melasma.
2. Hormonal Changes: Pregnant? Taking birth control or hormone replacement therapy? These can cause melasma due to hormonal fluctuations.
3. Pregnancy: Often called the “mask of pregnancy,” melasma can occur when expecting due to increased hormones.
4. Cosmetics: Skin products that irritate the skin may worsen melasma.
5. Genetics: If family members have it, there’s a higher chance you might develop it too.
6. Thyroid Disease: An overactive or underactive thyroid can affect hormones and lead to melasma.
7. Medications: Some drugs, like anti-seizure meds, can cause melasma as a side effect.
8. Skin Treatments: Procedures that irritate the skin may trigger or worsen melasma.
9. Stress: Constant stress can affect your hormones, making melasma more likely.
10. Allergies: Reactions to soaps, sunscreens, or cosmetics can increase your risk.
11. Darker Skin: People with darker skin types are more prone as they have more active melanocytes.
12. Lack of Sunscreen: Not wearing sunscreen can expose your skin to harmful rays, causing melasma.
13. Certain Foods: Some believe foods that increase skin’s sensitivity to the sun, like citrus fruits, can trigger melasma.
14. Liver Dysfunction: Your liver helps balance hormones. If it’s not working right, melasma can appear.
15. Endocrine Disorders: Disorders that affect hormone production can be behind melasma.
16. Blue Light: Exposure to screens emitting blue light (phones, computers) might contribute.
17. Inflammation: Any skin inflammation can increase the risk of developing melasma.
18. Vitamin Deficiency: Lack of essential vitamins may make your skin more susceptible.
19. Aging: As you age, changes in hormones and skin sensitivity can cause melasma.
20. Health Conditions: Some conditions, like Addison’s disease, can lead to melasma.
21. Harsh Weather: Extreme weather conditions can affect your skin’s melanin production.
22. Chemicals: Exposure to certain chemicals might trigger melasma.
23. Smoking: Smoking affects your skin health and can lead to various skin conditions, including melasma.
24. Excess Iron: Too much iron in the body may result in skin discoloration.
25. Ineffective Skin Products: Using the wrong skincare products may not protect against melasma triggers.
26. Skin Injuries: After an injury, the skin may respond by overproducing melanin.
27. Hormonal Disorders: Conditions like polycystic ovary syndrome can disrupt hormones and lead to melasma.
28. Heat: Excessive heat can stimulate melanin production, even without sun exposure.
29. Tanning: Artificial tanning can cause an uneven melanin response.
30. Improper Skincare Routine: Not cleansing or exfoliating properly can lead to clogged pores, making skin more susceptible.

Symptoms

Here, we’ll discuss associated features or characteristics of melasma to help you better understand it.
