What are the different types of acne lesions?

Yes. Dermatologists classify acne into three types: comedonal (black and whiteheads), inflammatory(pimples), and cystic (deep acne cysts). Comedonal acne responds well to topical treatments (benzoyl peroxide, retina, etc), while inflammatory acne may need a combination of topicals and oral medications. Most patients with cystic acne do best with oral antibiotics or accutane.
