Effective ingredients and treatments for melasma

Melasma is a skin condition characterized by irregular brown pigmentation, commonly appearing on the face. Treatments focus on reducing melanin production, impeding pigment formation, or encouraging cell turnover.

Hydroquinone remains a primary treatment for inhibiting abnormal pigmentation growth. While effective, it carries risks such as dermatitis, dry skin, and ochronosis—a potentially permanent dark-blue pigmentation. Due to these side effects, its use has been banned in certain countries. Dermatologists often prescribe concentrations between 8% and 12% for short-term use, though over-the-counter options typically cap at 2%.

Azelaic acid is noted as an effective alternative that selectively targets abnormal pigment cells while sparing normal ones, often without the side effects associated with hydroquinone. Other common active ingredients used in topical creams and serums include kojic acid, retinoids, niacinamide, and salicylic acid.

Melasma is categorized into several types: epidermal (superficial layers), dermal (throughout the dermis), mixed, and excess melanocytes, which is more common in individuals with darker skin tones.
