tretinoin

Tretinoin is a topical medication derived from vitamin A, commonly used in dermatology to treat various skin conditions. It is primarily utilized for the treatment of acne, as it helps to promote skin cell turnover, reduce the formation of new acne lesions, and improve skin texture. Tretinoin is also employed in the treatment of photoaging, as it can diminish the appearance of fine wrinkles, hyperpigmentation, and rough skin by stimulating collagen production and increasing epithelial cell turnover. It is available in various forms such as creams, gels, and liquids, and is known for its effectiveness in promoting skin health. Tretinoin is often prescribed with specific guidelines regarding application frequency and dosage, as it may cause skin irritation and increase sensitivity to sunlight.
