How to Handle It: Think of these as bigger, pissed-off whiteheads. Your best bet, says Zeichner, is to stock up on benzoyl peroxide, which kills the bacteria. A spot treatment like Murad Acne Spot Fast Fix ($22) should do the trick. Also, try not to pop them — as tempting as that may be. Since they're inflamed, they're more likely to scar if you go the DIY route.
Use a toner after cleansing. After you wash your face, exfoliate, or apply a face mask, apply a toner to the entirety of your face. Toners work to tighten pores making it less likely that dirt and oil will become trapped in them. Buy acne toners at a local drugstore, or use witch hazel or apple cider vinegar dabbed on with a cotton ball. Don’t rinse toners after application - allow them to stay on your skin.
The earliest pathologic change is the formation of a plug (a microcomedone), which is driven primarily by excessive growth, reproduction, and accumulation of skin cells in the hair follicle. In normal skin, the skin cells that have died come up to the surface and exit the pore of the hair follicle. However, increased production of oily sebum in those with acne causes the dead skin cells to stick together. The accumulation of dead skin cell debris and oily sebum blocks the pore of the hair follicle, thus forming the microcomedone. This is further exacerbated by the biofilm created by C. acnes within the hair follicle. If the microcomedone is superficial within the hair follicle, the skin pigment melanin is exposed to air, resulting in its oxidation and dark appearance (known as a blackhead or open comedo). In contrast, if the microcomedone occurs deep within the hair follicle, this causes the formation of a whitehead (known as a closed comedo).
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.
