HOW DOES ACNE HAPPEN?
Acne occurs when hair follicles become clogged by skin cells that block the opening of pores. Simplified, if the blocked pore is not visible, it forms a whitehead or pustule; if the pore is open and visible, it forms a blackhead. The most common form of acne, acne vulgaris, is a combination of whiteheads, blackhead, papules and pustules. Very difficult cases of acne may require prescription antibiotics, both topical and oral. Unfortunately, strains of acne-associated bacteria have grown resistant to many of the antibiotics which have been used to treat acne.
