Salicylic acid can be found in a number of over-the-counter (OTC) and prescription products. Salicylic acid does not work to kill the bacteria that causes acne, but it does encourage the sloughing of dead skin cells that can clog the pores and result in acne lesions. Although it can be irritating to the skin, salicylic acid helps to reduce acne outbreaks.
Significance
Salicylic acid is a keratolytic agent, meaning when it is applied to the skin it helps to reduce inflammation and unplug the oil, dead skin cells and dirt that can cause the pores to become clogged, according to Medline Plus. These qualities also make salicylic acid useful for reducing moles, warts and/or birthmarks.
Time Frame
Because salicylic acid does not kill the Propionibacterium acnes that causes acne, but instead reduces pore clogging, it must be used continuously over time to see results, according to the Skin Care Physicians website. If you have experienced acne-clearing benefits due to salicylic acid use, when you stop use of the medication, it can result in the return of your acne breakouts.
Types
According to the Mayo Clinic, topical salicylic acid is available in a variety of treatment forms including as a soap, foam, gel, cream, medicated pad, stick or liquid. Some brand names that contain salicylic acid include Oxy Balance, Stri-Dex, Avosil, Betasal and Palmer's Skin Success Acne Cleanser.
Warning
Although salicylic acid does not require a physician's prescription to purchase OTC, salicylic acid is not without its side effects. You should use small amounts when you begin treatment--otherwise, redness or irritation can occur, according to MedlinePlus. However, you should never use salicylic acid treatments when you have broken, irritated or infected skin.
Solution
Salicylic acid can be used in higher concentrations as a spot treatment for acne blemishes, according to the Mayo Clinic. When using as a spot treatment, you should apply a small dab to begin once per day and gently rub in.
If using it as a face wash, try using the face wash once a day to begin and then use as needed, according to the Mayo Clinic. Place a dab on your hand, and rub your hands together to create a lather. Rinse with warm water. If your face does not show signs of redness or irritation, you may use it twice daily.
