Melasma Causes & Treatment
What is Melasma
Melasma is a very common patchy brown, tan, or blur-grey facial skin discolouration, usually seen in women in the reproductive years.
It generally forms on the forehead, upper cheeks, upper lip, and chin of women who are between 20 to 50 years old. Factors such as exposure to sunlight, intake of birth control pills and similar external hormones, and internal hormonal changes such as those caused by pregnancy. People suffering from melasma are usually found to have a history of constant exposure to sunlight, while heat is also believed to be responsible for the condition. Melasma is most prevalent among pregnant women, particularly from Latin and Asian descent. It has been observed in relatively higher ratios in people with olive complexion, or darker skin - Hispanic, Asian, and Middle Eastern natives and ancestry.
What Causes Melasma?
Although the specific cause of melasma is yet to be conclusively determined, medical experts opine that several factors - pregnancy, birth control pills, hormone replacement therapy, family history of melasma, and race, could be the conditions favoring the manifestation of melasma, particularly in persons with a tendency for this condition.
Melasma occurring during pregnancy, is also known as chloasma. During pregnancy, women in their second and third semesters, experience a rise in levels of hormones such as oestrogen, progesterone, and melanocyte-stimulating hormone (MSH). Melanocytes, as many of us are aware, are the cells responsible for skin pigmentation. However, in the case of pregnancy-related melasma, increased levels of progesterone are believed to be the cause, and not oestrogen or MSH. Some studies have also established the link between increased incidence of melasma and progesterone therapy, in post-menopausal women.
Moreover, some products or treatments that cause skin irritation the skin, are known to result in increased melanin production, and thus increase melasma symptoms.
Similarly, persons having a genetic predisposition or family history of melasma are potentially more vulnerable the possibility of developing melasma. Such people must avoid exposure to sunlight, and step outdoors only after applying extra sunblock to prevent stimulation of pigment production.
Treatment for Melasma
Two types of patients are prone to suffer from Melasma;
1) Women who develop Melasma as a result of hormonal changes due to pregnancy or the use of birth control pills. For these individuals, the melasma condition will gradually subside after delivery, or once they stop using birth-control pills.
2) Individuals who are afflicted with long-term or permanentMelasma, following exposure UV rays and other factors.
