LEARN MORE ABOUT MELASMA
Melasma is a disorder of skin pigmentation, which is characterized by appearance of tan to dark brown patches of pigmentation on the face. They mostly appear over both cheeks, but can be seen on the nose, forehead and/or upper lip as well. This condition is more common in women of darker races like Indians, other Asians, Middle- Easterners and Hispanics. Only 10% of those affected are men. They patches appear darker in summers and can partially fade away during winters.
The precise cause of Melasma is not known.
A lot of men and women with melasma know of someone in their immediate family who also has similar dark patches.
Melasma is more common in women who are in their reproductive years, unlike 'liver spots' which are more common after menopause. Changes in hormonal status can definitely influence the appearance of melasma. For instance, chloasma (a variety of melasma) appears during pregnancy, and has been referred to as the 'mask of pregnancy'. In most cases, chloasma disappears completely within 6 months of the delivery, when the hormonal fluctuations settle down. Similarly, melasma can appear due to hormonal changes influenced by birth control pills. However, hormone replacement therapy (HRT) used after menopause has not been shown to cause the condition.
Melasma has also been found to occur among patients using certain sunlight- sensitizing medications (eg, antibiotics like Rifampicin, certain medications used to treat ovarian and thyroid disorders). There are certain cosmetics are well which can be sunlight- sensitizing.
Melasma is also more frequent along those who spend a lot of time in
outdoor occupations and hobbies. This is because people of darker races
have more active melanocytes in their skin. When these melanocytes are
stimulated by sunlight, especially in the 'convex' areas of our face,
like the cheeks, nose or chin, they produce very large amounts of
pigment, which gets deposited as Melasma.
Melasma is not associated with any internal disease or deficiency. It has no complications other than the fact that it is cosmetically unsightly.
Melasma is diagnosed by its typical appearance. Your dermatologist might decide to perform a Wood's lamp test to ascertain the depth of the pigment and to rule out other disorders like unusual birthmarks.
Although there is no cure for melasma, there are plenty of treatment options available today, which can fade away the excess pigment to give a more natural and even appearance.
Sunscreens are essential in the treatment of melasma, and they will have to be used life-long as melasma tends to recur every summer. A broad spectrum sunscreen with SPF 30 or higher is ideal. They have to be used everyday, irrespective of the weather or your activity.
Any cosmetic which irritates the skin must be discontinued. Your dermatologist can help you choose cosmetics which are safe for you. Do not discontinue any medication. Your melasma can be lightened with treatment, even as you continue taking the tablets prescribed to you by other doctors.
Melasma can be faded away with skin lightening creams like hydroquinone or kojic acid. Our facility also offers chemical peels, microdermabrasion and the Q-switched Nd:YAG laser, for more aggressive treatment of melasma. We caution you against non-physicians claiming to treat melasma with the above-mentioned treatments, as these procedures can cause severe complications at the hands of untrained and unsupervised individuals. Treatment of melasma requires a comprehensive, professional and step-wise approach by an experienced dermatologist. Melasma cannot be faded away in days. It will take at least 2-3 months of regular therapy to obtain appreciable results.
