Melasma is a skin condition where the face takes on a brownish color. It is Hyperpigmentation: an unnatural-looking increase in pigmentation, brought on by sun exposure, certain prescription medications or pregnancy. In fact, Melasma is often referred to as the “mask of pregnancy.” Melasma is most common in women between the ages of 20 and 40. Fortunately, Cosmelan depigmentation treatments are available to restore your face to its natural look. Based on the inhibition of tyrosine, which is the enzyme responsible for the melanin Hyperpigmentation, Cosmelan® is a formula available only from a plastic surgeon. After about one week, you’ll start to notice a difference. The excessive skin pigmentation will start to decrease, and your face will return to its normal appearance. We offer Cosmelan depigmentation treatments at both our San Francisco and Marin offices.
