Types of Acne and How to Treat Them (4 of 4)

Pustules

Pustules can also happen when walls of pores are broken down, but this type also forms pus. The pore is filled with pus, and forms a white or yellow head on top. The surrounding area is usually red in color.

Nodules

Nodules happen when the pores are swollen and clogged, but are further irritated and get even bigger. The nodules are rooted deep within the skin, unlike papules and pustules that rest on top of the skin. They cannot be treated as easily, and require the assistance of a dermatologist. They will likely prescribe an oral medication like isotretinoin. This will treat the problem with boosted levels of vitamin A, and is taken for up to six months.
