Melasma is a type of hyperpigmentation that is common in women, especially during and after pregnancy. It normally appears as large dark patches on the face although other parts of the body can be affected. This article looks at what causes melasma and explains some steps you can take to help reduce the appearance of dark patches on your skin.
Melasma, also known as chloasma, is a form of hyperpigmentation that appears on the face, especially on the cheeks, bridge of the nose, forehead and upper lip and sometimes on other sun-exposed parts of the body, such as the forearms. Men can experience melasma, but it is much more common in women.
Melanin is the pigment that defines the color of a person’s skin, and melasma is caused by an increase in melanin production. This increase is thought to be triggered by changes in hormone levels, especially those caused by pregnancy and oral contraceptives, as well as by the sun.
Melasma is not in any way harmful but can cause distress when it is very noticeable.
Between 10–15 percent of pregnant women experience melasma1 and the condition is sometimes referred to as “the mask of pregnancy”.
During pregnancy endogenous hormones (meaning the hormones that are produced naturally within the body) stimulate the melanocytes (the melanin producing cells located in the basal layer of the epidermis) causing them to produce more melanin.
Melasma and oral contraceptives
Between 10–25 percent of women taking oral contraceptives1 experience melasma. Women who take birth control pills undergo similar kinds of hormonal changes as those that occur during pregnancy. Unlike age spots, melasma can disappear of its own accord after birth or if estrogen intake is reduced.
The sun is a major contributor to, and aggravator of, the development of melasma and other factors such as family predisposition, age and certain anti-epilepsy drugs can also play a role.
There are three types of melasma:

A sensible attitude to sun protection is the most significant step you can take to helping to prevent or reduce the severity of melasma. Limit the time you spend in the sun, keep out of the sun during its most intense hours and wear protective clothing and sunhats whenever possible. This is particularly important if you have a genetic disposition to melasma (i.e. it runs in your family) or if you are pregnant, on the pill or taking another form of hormone supplement.
Sun protection is not just for sunbathers. The sun’s rays effect skin even on cloudy days, so give your skin the daily protection it needs. As well as reducing hyperpigmentation, Eucerin Anti-Pigment Day SPF 30 offers effective UVA and UVB (SPF 30) protection and prevents the formation of additional sun-induced pigment spots. If you’re going to be spending time in the sun choose a high or very high factor sun protection product which has been specially formulated for your skin type and condition and reapply it regularly.

Dermatological treatments such as chemical peels and laser therapy can help to reduce melasma. Epidermal melasma is the easiest type to reduce but, due to the depth of the melanin pigments in dermal and mixed melasma, these types can be harder to treat.
Dermo-cosmetic skincare products can be used daily to help to extend the results of dermatological treatments. All four products in the Eucerin Anti-Pigment range – a day cream, a night cream, a dual action serum and a spot corrector – contain Thiamidol, an effective and patented ingredient that acts at the root cause of hyperpigmentation by reducing melanin production. It has been clinically and dermatologically proven to reduce dark spots and prevent their re-appearance.
Melasma and age spots are harmless. Melanoma (a type of skin cancer) can be life-threatening. If you have any concerns about your pigment spots – if they change shape, size and color or if they become itchy and start to bleed – it’s important that you consult your doctor.
