acne

Many products which used to be prescription only are now available over-the-counter (OTC). Adapalene - a retinoid and benzoyl peroxide - an antibacterial are two such acne products.

• Adapalene 0.1% gel is OTC (the 0.3% gel is prescription) - retinoids work by dissolving blackheads, preventing blackheads from forming, and reducing inflammation. Bonus, they are also used to treat wrinkles, a two-fer.

• Benzoyl peroxide (BPO) is available in various strengths (0.25% to 10%) and formulations (gel, lotion, wash, etc.) - this antibacterial works by killing acne-causing bacteria and dissolving excess skin cells.

DO: A reasonable strategy would be an initial trial of BPO. It can be harsh particularly on sensitive skin or if left on too long. Avoid using around the eyes, mouth, and folds of the nose. If tolerated and additional control is required, adapalene could be added. If BPO is not working, you could switch to adapalene. Adapalene can also be harsh; avoid the same sensitive areas. Adapalene is labeled for daily use, but if you have sensitive skin, you may want to “work up” to this frequency by starting less frequently (ex. every other day).

DON’T: start both products at the same time. This could cause double the side effects and you won’t know which product is (or is not) working.

OTHER: I don’t recommend any particular brand, but, as will all OTCs, I recommend looking at the “Active Ingredients” section to make sure you are getting the ingredient you are looking for. Many brands will sell different ingredients under, essentially, the same name. For example, Galderma makes both adapalene and BPO products as well as other “acne” products (ex. moisturizers, toners) - all branded as Differin®.

RANDOM: Anti-bacterials are drugs that kill or inhibit the growth of bacteria. Anti-biotics are antibacterials that are “naturally”-sourced (ex. from bacteria or molds).
