Botox. Botox is being used by dermatologists to both help prevent acne breakouts and scarring and to help relax the puckered skin around an already existing acne scar. Some dermatologists are treating acne with Botox by injecting the areas on the face where more oil is produced.

Why does Botox help acne?

A typical Botox treatment that targets acne involves injecting a small amount of the neurotoxin into key muscles of the face. It minimizes blemishes by blocking and paralyzing acetylcholine, which is released by nerves into the muscle.

How long does Botox for acne last?

Botox is temporary, lasting about four to six months. If you like the results, you may decide to continue with several treatments a year.
