What Is Melasma and Why Do Dark Patches Appear?
Melasma is a common pigment disorder that causes brown and gray patches on the face, most often on the forehead, upper lip, and cheeks. Many patients in Northridge notice these patches becoming more pronounced during the summer months, leading to confusion about whether they are dealing with sun spots, aging, or something more persistent.
Melasma develops when melanocytes become overactive and produce excess melanin. This increased pigment results in visible discoloration that can be difficult to fade without medical guidance. Sun exposure, heat, and hormonal fluctuations are common triggers. Pregnancy and birth control are well-known contributors, which is why melasma is more frequently seen in women and in individuals with darker skin tones.
How Melasma Is Treated
Melasma is treatable, but it requires consistency and realistic expectations. Treatment options may include prescription topical medications, chemical peels, laser therapies, and in some cases oral medications. The foundation of every melasma treatment plan, however, is strict sun protection.
Daily use of a mineral sunscreen with SPF 50 or higher, ideally tinted to block visible light, is essential. Sunscreen should be applied every day, regardless of weather or indoor activity, as UV and visible light can continue to stimulate pigment production.
Melasma is considered a chronic condition, meaning it can relapse if triggers return. Long-term management and maintenance are often necessary to maintain improvement.
