Tretinoin is primarily used as a topical medication to treat acne and various skin conditions. It helps by promoting skin cell turnover, which keeps pores clear and reduces the number and severity of pimples, blackheads, and whiteheads. Additionally, tretinoin is used to improve the appearance of sun- damaged skin, including fine wrinkles, dark spots, rough skin texture, and hyperpigmentation caused by sun exposure. It is also employed as an anti-aging treatment to reduce fine wrinkles and improve skin texture and thickness

. Tretinoin is a form of vitamin A (retinoic acid) and belongs to the retinoid class of medications. It is available in creams, gels, and lotions, and is sometimes combined with other agents like clindamycin or hydroquinone for enhanced effects, such as in the treatment of melasma or acne

. In summary, tretinoin is used for:

• Treating acne (both inflammatory and noninflammatory)
• Reducing fine wrinkles and signs of photoaging
• Improving dark spots and skin discoloration
• Enhancing skin texture and thickness
• Treating sun-damaged skin
