Melasma is a dark, mask-like mark (often called the mask of pregnancy) that is common, painless, and usually goes away on its own after a few months.

Melasma vs. hyperpigmentation -

Melanin is a substance in your body that produces hair, eye, and skin pigmentation. If skin cells are unhealthy, they can make too much melanin, leading to areas on your skin that look darker than the rest. This is called hyperpigmentation.

Melasma vs. hyperpigmentation -

Darker patches on your face or neck can be a sign of melasma. Hyperpigmentation on your skin could be due to things like sun exposure, medical conditions, hormonal changes, adrenal disorders, genetics, or lack of vitamin D.

Melasma causes -

Pregnant people are most at risk of melasma due to an increase in the hormones estrogen and progesterone. While anyone can be affected by melasma, women are 90% more likely to experience it than men.

What are other triggers of melasma? -

More research is needed, but heavy exposure to sunlight, tanning beds, stress, birth control pills, and thyroid disease may trigger melasma.

Epidermal melasma -

Epidermal melasma affects the top layer of the skin. Patches that appear on the face are dark brown in color, and the shape is relatively uniform.

Dermal melasma -

Dermal melasma affects the deeper layer of your skin (the dermis). It is usually a bluish-gray or gray-brown color and has a blurry border. Because the melasma is deeper in the skin, it requires treatment from a dermatologist.

Melasma diagnosis -

A dermatologist will be able to confirm if you have melasma. They'll take a look at your skin, and to rule out any other conditions, they may order a biopsy where a small piece of your skin will be removed and examined.

Melasma diagnosis -

Your dermatologist may ask you questions to help diagnose melasma, such as when did you first see a darker color on your skin and what soaps do you use? You may wish to take notes before your appointment to prepare.

Seeing a dermatologist -

Seeing a dermatologist will ensure you receive the right diagnosis. Dark patches can be birthmarks, a result of light sensitivity, or overuse of skin-lightening creams.

Melasma treatment -

Depending on the type of melasma, it may be treated with creams to stop new dark patches from forming. Hydrocortisone, azelaic acid, and methimazole are commonly prescribed topical treatments.

Platelet-rich plasma -

Platelet-rich plasma involves taking a small amount of your blood, processing it in a machine, and then injecting it into your body, helping to even the skin tone.

Living with melasma -

Having a noticeable skin condition can put a strain on your mental health. If you find it difficult to live with melasma, contact your doctor or a therapist to help you find tools to cope.

Melasma diet? -

More research is needed to learn how foods impact melasma. Currently, doctors don't know if certain foods can affect it.

Vitamin D -

While more research is needed to discover if there is a link between diet and melasma, foods high in vitamin D are proven to keep your skin healthy. Try meat, eggs, milk, mushrooms, and salmon.

Vitamin D -

If your vitamin D levels are still low after incorporating vitamin D-rich foods into your diet, talk to your doctor about prescription or over-the-counter supplements.
