Tretinoin cream, a topical retinoid derived from Vitamin A, speeds up skin cell turnover, preventing clogged pores that cause acne. It also helps with skin texture, reducing the appearance of fine lines and wrinkles. Consistent use can result in clearer skin, though initial irritation, redness, and peeling are common. Dermatologists recommend applying a pea-sized amount at night and using sunscreen during the day.
