Melasma

What is melasma?  What are signs of melasma?

Melasma is a very common patchy brown, tan, or blue-gray facial skin discoloration, almost entirely seen in women in the reproductive years. It typically appears on the upper cheeks, upper lip, forehead, and chin of women 20-50 years of age. Although possible, it is uncommon in males.

It is thought to be primarily related to external sun exposure, external hormones like birth control pills, and internal hormonal changes as seen in pregnancy. Most people with melasma have a history of daily or intermittent sun exposure. Melasma is most common among pregnant women, especially those of Latin and Asian descents. People with olive or darker skin, like Hispanic, Asian, and Middle Eastern individuals, have higher incidences of melasma.

What causes melasma?

The exact cause of melasma remains unknown. Experts believe that the dark patches in melasma could be triggered by several factors, including pregnancy, birth control pills, hormone replacement therapy (HRT and progesterone), family history of melasma, race, anti-seizure medications, and other medications that make the skin more prone to pigmentation after exposure to ultraviolet (UV) light. Uncontrolled sunlight exposure is considered the leading cause of melasma, especially in individuals with a genetic predisposition to this condition. Clinical studies have shown that individuals typically develop melasma in the summer months, when the sun is most intense. In the winter, the hyperpigmentation in melasma tends to be less visible or lighter.

A combination of skin care, peels and Laser treatments have proven to be effective in minimizing the appearance of melasma.
