Salicylic acid is a topically applied beta-hydroxy acid that stops bacteria from reproducing and has keratolytic properties.[131][132] It opens obstructed skin pores and promotes shedding of epithelial skin cells.[131] Salicylic acid is known to be less effective than retinoid therapy.[20] Dry skin is the most commonly seen side effect with topical application, though darkening of the skin has been observed in individuals with darker skin types.[1]

All acne is not, actually, created equal. This makes perfect sense, seeing as there are so many factors — i.e. hygiene, hormones, and genetics — that can both lead to and exacerbate your breakouts. But knowledge is power, and just knowing that there are different types, and that each kind requires its own plan of attack, puts you ahead of the clear-skin curve. Once you figure out what you're working with, it gets far easier to treat. Here, your ultimate guide to identifying, and then taking down, every type of acne out there, according to dermatologists. Find out how to identify and deal with the different kinds of acne, including blackheads, whiteheads, blind pimples, and cystic zits.


Misperceptions about acne's causative and aggravating factors are common, and those affected by it are often blamed for their condition.[176] Such blame can worsen the affected person's sense of self-esteem.[176] Until the 20th century, even among dermatologists, the list of causes was believed to include excessive sexual thoughts and masturbation.[165] Dermatology's association with sexually transmitted infections, especially syphilis, contributed to the stigma.[165]
The treatment regimen your doctor recommends depends on your age, the type and severity of your acne, and what you are willing to commit to. For example, you may need to wash and apply medications to the affected skin twice a day for several weeks. Often topical medications and drugs you take by mouth (oral medication) are used in combination. Pregnant women will not be able to use oral prescription medications for acne.
