Acne affects the oil glands and hair follicles within the skin, usually on the face but sometimes on other areas of the body too such as the neck and back. The pores, which connect to oil glands produce sebum, a substance which carries dead skin cells to the skin’s surface, but sometimes the oil and skin cells plug the pore instead. The bacteria, which usually live harmlessly on the skin contaminate the plugged follicle and this can cause an infection which develops into acne. There are a number of different forms that this infection manifests itself as including papule, pustules, cysts and nodules but all fall under the term Acne.
Due to the infection being the main cause of acne, it is crucial you treat it as you would any other infection, with a medication such as Differin which works to clear the acne and stop further development of spots, whilst healing and decreasing any chance of scarring.
