When sebum, dead skin cells, and bacteria build up in hair follicles, acne and other blemishes are often the result. IPL’s heat and light energy help to clear and balance blemished skin by destroying the bacteria that collects in the follicles. In addition, it is thought that IPL therapy helps to lessen the production of oil by the sebaceous glands, which can further help to diminish the excessive buildup of debris in the follicles.
