"Salicylic acid can exfoliate the skin as well as decrease inflammation". "The cells in the lining of the hair follicles of people with acne tend to multiply quickly, and stick to one another. Salicylic acid works by dissolving this cement that holds those sticky cells together in the clogged pores. Most effective acne treatments can make skin a bit red and inflamed while the skin adjusts to them. This ingredient is unique because it's very effective at fighting acne, but it has a soothing, calming effect on skin. The anti-inflammatory properties of this ingredient are not surprising, given its close chemical relationship to one of the most well-known anti-inflammatory drugs available, acetylsalicylic acid (also known as aspirin!)."
"Problems can arise when high concentrations of salicylic acid are applied to a large area of skin for a long period of time. When this occurs, something called salicylate toxicity can occur. That being said, the concentrations of salicylic acid found in over-the-counter products designed to treat blemishes (and the dark marks they leave behind) are too low to cause trouble. Some over-the-counter wart treatments, on the other hand, have much higher concentrations of salicylic acid, so you wouldnt want to spread those all over your body! Levels of salicylic acid found in products designed to clear your complexion are usually very well tolerated. They almost never cause irritation or peeling when used once or twice a day."
Benzoyl Peroxide: What To Know
"Benzoyl peroxide is a powerful ingredient that is effective against all kinds of acne lesions (blackheads, whiteheads, and big red pimples). It is bactericidal, meaning it kills bacteria, rather than simply slowing down their growth. It also works very quickly, improving acne as early as five days after starting treatment. It_s a great first line treatment for acne, but it_s also helpful to use in combination with antibiotics. In fact, benzoyl peroxide has the ability to prevent antibiotic resistance!"
"One thing to watch out for with benzoyl peroxide is that it can bleach dark fabrics. Be sure to apply the benzoyl peroxide after you pull that navy sweater over your face! It can also cause drying, peeling, and redness if it_s not delivered in the right amount, surrounded by the right mix of ingredients."
