Tretinoin, also known as all-trans retinoic acid, is medication used for the treatment of acne and acute promyelocytic leukemia. For acne, it is applied to the skin as a cream, gel or ointment.

Is Tretinoin a Retinol?

Retinoids are a group of compounds derived from vitamin A. Tretinoin and retinol both fall under this umbrella. Both tretinoin and retinol are topical skin care products that can treat the same conditions. They both promote rapid exfoliation and stimulation of collagen and elastin, which leads to smoother-looking skin.

What Does Tretinoin Do?

Tretinoin (Altreno, Atralin, Avita, Retin-A) is used to treat acne. Tretinoin is also used to reduce fine wrinkles (Refissa and Renova) and to improve spotty discoloration (Renova) and rough feeling skin (Renova) when used along with other skin care and sunlight avoidance programs.

How long does Tretinoin take to work?

You may notice tretinoin starting to work within 2 to 3 weeks, but it can take 6 weeks or more to experience the full benefit. If you don’t see improvement within 12 weeks, or if you have significant improvement and wonder if you should start using it less frequently, talk to your doctor.
