In the mild stage, minor pimples, blackheads and whiteheads can be observed. In the moderate stage a greater amount of blackheads, pimples and a few pustules can be seen. In the severe acne stage, a larger amount of pustules and papules along with significant inflammation (leading to high risk of scarring) is visible.
