Face products with salicylic acid are most commonly used to treat acne. According to AcneNet, this medication works by getting rid of dead skin cells and keeping your pores clear of the debris that can block them and lead to pimples. It is available over-the-counter in face washes, lotions, gels and creams, or your doctor can prescribe you a stronger form of one of these products.
Function
Salicylic acid softens a protein in your skin's structure known as keratin. DermNet NZ states that this action aids in sloughing off old skin cells and unclogging your pores. When used to treat acne, this medication slows down the rate at which your skin gets rid of dead cells inside your pores, which helps keep them from becoming clogged. It also reduces the appearance of pimples by exfoliating the skin and helping blemishes clear up more quickly.
Application
Talk to your doctor before you add any new products to your skin care regimen, as salicylic acid may interfere with certain medications or exacerbate other skin conditions, says the Mayo Clinic. Do not use it more often than stated on the product label or as recommended by a health care provider. If you are using the cleanser, wet your face with warm water, lather the cleanser in your palms and smooth it over your skin. Rinse off when you finish and pat dry. Do not use the cleanser more than twice a day. For the lotion, gel or cream, apply a thin layer to clean, dry skin twice a day, or as instructed by a dermatologist.
Complementary Treatments
While salicylic acid unclogs pores, it does not inhibit the production of acne-causing bacteria, says AcneNet. Your doctor can prescribe you a topical antimicrobial like benzoyl peroxide or clindamycin to kill the bacteria, and you can use this in conjunction with your salicylic acid product if he instructs you to do so.
Considerations
Do not use salicylic acid while also using abrasive or drying skin products or those that contain alcohol, unless your doctor permits this. Because salicylic acid sheds your top layers of skin, it can make your complexion more sensitive and prone to irritation, as well as sunburn. Apply a sunblock before going outdoors to avoid incurring sun damage.
Warnings
Salicylic acid can cause reddening or mild stinging upon application, but this typically subsides after a few weeks of treatment. Talk to your doctor if you experience these or other persistent side effects, and do not apply the product to broken or irritated skin, as this can exacerbate irritation.
