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.
How to Handle It: If you've tried the usual anti-acne ingredients, like salicylic acid and benzoyl peroxide (which, we should warn you, rarely work for this), you should consider paying your dermatologist a visit. "You may need a cortisone injection or an oral medication, like an antibiotic, in addition to topical formulas," says Zeichner. He's also a fan of a prescription topical medication called Epiduo Forte Gel, since, he says, it's been shown to be effective at controlling severe acne without the help of oral treatments.
What's Going On: If it's big, red, and painful, you're probably experiencing cystic acne, one of the more severe types. "Cystic pimples are caused by genetics and hormonal stimulation of oil glands," says Zeichner. Not only are they large, but they're also notoriously tough to treat. They often recur in the same place, because even if you manage to get rid of one, it can keep filling up with oil again and again, like an immortal pimple.
Scars (permanent): People who get acne cysts and nodules often see scars when the acne clears. You can prevent these scars. Be sure to see a dermatologist for treatment if you get acne early — between 8 and 12 years old. If someone in your family had acne cysts and nodules, you also should see a dermatologist if you get acne. Treating acne before cysts and nodules appear can prevent scars.
