"Acne is the result of an overproduction of sebum - an oily material that prevents the skin from drying out. The skin becomes oilier, shinier and thicker on the surface. This excessive secretion, when located at the level of the hair follicles, causes them to block. Bacterial growth is then encouraged resulting in the formation of blackheads, inflammations and acne pimples. Labelist Pure Shine Control Range helps you regulate excess sebum. Try it!
