Adult acne is multifactorial and is due to a combination of genetics, hormones, foods and stress. Unlike teenage acne, adult acne is more persistent and much more resistant to treatment. Adult acne favors areas such as the chin, jawline and cheek area, and can present as deep lying pimples and blind ended cysts. Most patients tend to pick their acne lesions, and the tendency to pick is compounded by stress and hormonal factors.
