What is tretinoin topical?

Tretinoin is used to treat acne, sun damage and as an anti-aging product to help reduce the appearance of fine wrinkles and dark spots.  Tretinoin cream or gel works by helping the skin renew itself, decrease comedone formation, and also help with hyperpigmentation. The Retin-A brand of tretinoin is used for acne and Renova brand is used to help sun-damaged skin and fine wrinkles. Tretinoin cream and gel is a form of vitamin A and is sometimes called retinoic acid.

Tretinoin for acne helps reduce the number and severity of pimples, blackheads, whiteheads, and also helps to improve dark spots (hyperpigmentation). 

Tretinoin cream for skin aging may help improve fine wrinkling, hyperpigmentation, roughness, and epidermal thickness. When tretinoin is used for photoaging of the skin it should be used along with other treatments, comprehensive skin care, and avoiding sun damage.

Tretinoin topical became an FDA-approved medicine on October 20, 1971.  Tretinoin is now available as a generic product.

Tretinoin is also an ingredient in combination products:
