Like the well-known and well-dispised acne, backne is a skin condition in which pores become clogged and infected easily, due to massive oil production, hormones, and/or poor hygiene. It generally plagues young women with long hair, but can effect almost anyone. the worst part is, 50% of all sufferers aren't aware that they have it.
