Salicylic acid is a type of medication called a keratolytic agent, according to MedlinePlus. It has a variety of useful effects, like easing redness and swelling on the skin, softening it and loosening dry or thickened patches so they can fall off naturally. It is useful for several different skin conditions, including acne, because of this action.
Use
Salicylic acid is used on pimples that have not become inflamed, notes the American Academy of Dermatology. It unplugs clogged pores and stops abnormal shedding of dead skin cells, which relieves existing pimples and prevents future pore blockages. It is not a comprehensive treatment because it does not affect excess skin oil production or bacteria, both of which also contribute to acne outbreaks.
Types
Several different types of over-the-counter acne-fighting products contain salicylic acid. AAD advises that it is commonly sold in medicated creams, lotions and saturated pads. Acne sufferers typically choose the form the product they find easiest to use, because salicylic acid must be applied daily or pimples will return.
Limitations
Salicylic acid is a reliable acne treatment for mild to moderate cases, but its usefulness is limited for severe outbreaks of inflamed pimples and cystic acne. Inflamed papules and pustules need more aggressive treatment before they develop into cysts. Otherwise, the ADA warns there is a high risk of scarring. A physician can prescribe appropriate treatments for cases that are too severe for salicylic acid products. MedlinePlus explains that salicylic acid must be used for several weeks to show its effectiveness, and use must continue to maintain the progress once the pimples have improved.
Alternatives
Other pimple treatments may work if salicylic acid does not control acne effectively for a particular person. Benzoyl peroxide acts on dead skin skills and also kills acne-causing bacteria, the AAD explains. Outbreaks can also be treated with products containing a combination of alcohol and acetone or resorcinol and sulfur. Extremely bad or stubborn pimples often need prescription creams or antibiotic pills.
Warning
MedlinePlus warns that salicylic acid sometimes irritates the skin when you first starts using it. The pimples may even seem worse for the first few days as the skin gets used to the treatment. MedlinePlus recommends cutting down on the amount of salicylic acid used or the frequency of application until the body adjusts and the irritation subsides.
Considerations
MayoClinic.com advises treating pimples carefully while using medications. Do not use harsh or abrasive soap while washing or scrub the affected skin. Refrain from scratching or popping pimples because this inflames them and leads to pustule and papule development.
