Sebaceous glands produce an oily substance called sebum. Breakouts occur when sebum gets trapped inside your hair follicles, usually with dead skin cells and bacteria. NeoClear’s powerful, deep-heating laser works by targeting the sebaceous glands, reducing their size as well as their sebum output. The laser also reduces inflammation and redness and encourages the production of collagen which will help diminish existing breakouts as well as acne scarring.
