What it is: You may have heard of tretinoin in reference to "Retin-A" wrinkle treatments. Tretinoin is retinoic acid and vitamin A acid combined, and comes in various strengths in creams, gels, and liquids for topical use on the skin. It is used to treat acne and also to treat sun damaged skin or wrinkles and is usually applied once per day.1Learn more from the U.S. National Library of Medicine.

Frequently used topical retinoids include adapalene, isotretinoin, retinol, tazarotene, and tretinoin. They often cause an initial flare-up of acne and facial flushing, and can cause significant skin irritation. Generally speaking, retinoids increase the skin's sensitivity to sunlight and are therefore recommended for use at night. Tretinoin is the least expensive of the topical retinoids and is the most irritating to the skin, whereas adapalene is the least irritating to the skin but costs significantly more. Tazarotene is the most effective and expensive topical retinoid, but is not as well-tolerated. Retinol is a form of vitamin A that has similar but milder effects, and is used in many over-the-counter moisturizers and other topical products.
Benzoyl peroxide attacks the P. acnes bacteria. However, one of its main side effects is dryness: If you’re going to use anything with benzoyl peroxide, make sure to moisturize afterwards. Sulfur and azelaic acid are less common and less severe alternatives to benzoyl peroxide. Dr. Peter Lio, assistant professor of clinical dermatology at Northwestern University, says sulfur-based treatments are “a good fit for patients who can’t tolerate the side effects of benzoyl peroxide.”
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
