Tretinoin

Hydroquinone, Tretinoin, and Fluocinolone Acetonide is the gold-standard Triple Combination Cream (Kligman's formula) for refractory melasma. Hydroquinone (2-4%) competitively inhibits tyrosinase, blocking melanin pigment synthesis; Tretinoin (0.05%) accelerates epidermal turnover and keratinocyte shedding, facilitating hydroquinone penetration and dispersing melanin; and Fluocinolone Acetonide (0.01%), a mild-to-moderate topical corticosteroid, suppresses melanocyte inflammation and counteracts the irritant dermatitis of hydroquinone and tretinoin. Indicated for the short-term moderate-to-severe melasma of the face.

Tretinoin (all-trans retinoic acid) is a topical retinoid on the WHO Model List of Essential Medicines. It binds to nuclear retinoic acid receptors (RAR), modifying gene expression to decrease follicular epithelial cohesiveness, stimulating mitotic turnover of follicular epithelial cells, expelling existing comedones, and preventing new microcomedone formation. Indicated for topical treatment of acne vulgaris and photoaged skin (fine facial wrinkles).
