Generic Name: tretinoin (TREH-tih-noyn)
Brand Name: Retin-A
Tretinoin liquid is used for:
Treating acne. It may also be used for other conditions as determined by your doctor.
Tretinoin liquid is a vitamin A derivative. How it exerts its beneficial effects against acne is not fully known. Tretinoin appears to increase skin-cell turnover and to reduce the tendency for skin cells to stick together. This reduces the formation of acne and allows quicker healing of acne that does develop.
Do NOT use tretinoin liquid if:
- you are allergic to any ingredient in tretinoin liquid
Contact your doctor or health care provider right away if any of these apply to you.
