What is tretinoina crema?

Tretinoin cream (brand name Retin-A) is a topical retinoid medication used to treat a variety of skin conditions, including acne, wrinkles, and photodamage. The cream is applied to the affected area of the skin and works by increasing the production of new skin cells and decreasing the production of sebum, an oily substance that can clog pores and lead to acne. Tretinoin cream can also improve the appearance of fine lines and wrinkles by stimulating the production of collagen and elastin fibers. Side effects include dryness, redness, irritation, and itching of the skin. Sun protection is important when using tretinoin cream since it can make the skin more sensitive to the sun.
