Compare Atralin vs. Tretinoin

Atralin and Retin-A are both topical forms of tretinoin, a retinoid medication used to treat acne. They work by unclogging pores and replacing old skin cells with new ones. Both medications are applied topically and require a prescription. Atralin comes as a topical gel, while Retin-A comes as a cream. But Retin-A also comes as a gel in the form of Retin-A Micro. Both medications are also available as lower-cost generics and are typically applied once daily at bedtime. Side effects can include skin irritation, redness, and peeling. Both medications make your skin more sensitive to sunlight, so it's important to use sunscreen and protective clothing when outdoors.
