Acne is an inflammatory skin problem seen usually over the face in young patients.
During the rapidly growing teenage years sebaceous glands over the face and scalp become very active under hormonal influence and discharge excessive oily secretions. Compounded by hormonal and genetic induced narrowing of the skin pores into which these glands open, oil accumulates as solid fat. Bacteria and yeasts break fat into fatty acids which produces inflammation and pus. Left untreated this can lead to scarring and pigmentation.
