The Anti-Redness Exfoliating Solution is mostly water, but its 2 percent salicylic acid is enough to eat through oil and remove the dead skin cells clogging your pores — and it boasts a higher concentration than nearly every other kit we looked at. Sodium hyaluronate, the super-moisturizing humectant we fell in love with in our review on the Best Face Moisturizer, also caught our eye sitting smack dab in the middle of the ingredients list.
Topical and oral preparations of nicotinamide (the amide form of vitamin B3) have been suggested as alternative medical treatments. It is thought to improve acne due to its anti-inflammatory properties, its ability to suppress sebum production, and by promoting wound healing. Topical and oral preparations of zinc have similarly been proposed as effective treatments for acne; evidence to support their use for this purpose is limited. The purported efficacy of zinc is attributed to its capacity to reduce inflammation and sebum production, and inhibit C. acnes. Antihistamines may improve symptoms among those already taking isotretinoin due to their anti-inflammatory properties and their ability to suppress sebum production.
Benzoyl peroxide is an antibacterial ingredient, and it’s very effective at killing the P. acnes bacteria that causes breakouts. But benzoyl isn’t without its downsides. The leave-on creams and cleansing treatments can dry out sensitive skin types and bleach clothing if you aren’t careful. Board-certified dermatologist Eric Meinhardt, M.D., previously told SELF that it's best to stick to formulations that have no more than 2 percent of benzoyl peroxide listed on the active ingredients chart; stronger concentrations are harder on your skin without being any tougher on bacteria.
Diet. Studies indicate that certain dietary factors, including skim milk and carbohydrate-rich foods — such as bread, bagels and chips — may worsen acne. Chocolate has long been suspected of making acne worse. A small study of 14 men with acne showed that eating chocolate was related to a worsening of symptoms. Further study is needed to examine why this happens and whether people with acne would benefit from following specific dietary restrictions.
