Melasma

Melasma causes uneven brown patches of pigmentation on the skin after sun exposure. At Ross Dermatology, medical dermatologists Kim Ross MD will offer several possible solutions for this very difficult to treat skin condition.

What is melasma?

Melasma is a common disorder that causes brown or gray patches of skin. It can appear as large, singular marks or a collection of freckles. Melasma commonly develops on the face, usually on the cheeks, upper lip, and forehead, or on the forearms secondarily to sun exposure. 

The condition can change over time, often and darkening during the summer. Sunblock is the first treatment option to prevent darkening.

What are the different types of melasma?

There are three main types of melasma:

Epidermal melasma

Epidermal melasma is a prominent type that causes dark patches of skin with defined borders.

Dermal melasma

Dermal melasma typically forms light, blueish-gray patches of skin without defined borders. 

Mixed melasma

Mixed melasma is a combination of dermal and epidermal melasma. It’s also the most common type.

What causes melasma?

The most common causes of melasma are hormonal changes and radiation exposure. Certain factors can also increase your risk of developing melasma, such as:

• Pregnancy
• Hypothyroidism
• Genetics
• Contraceptives
• Anti-seizure medications
• Makeup that causes a phototoxic reaction
• Certain soaps and skincare productBoth men and women develop melasma

What are the treatments for melasma?

Sometimes, melasma subsides on its own, but most people need professional treatments to reduce its pigmentation. The first step in treating melasma is diagnosing your type. Some types of melasma are harder to treat than others.
