Abstract
A method of reducing sebum production in human skin, used primarily for cosmetic purposes, including the prevention of acne vulgaris, comprising the use of pulsed light having a wavelength, if monochromatic, or a wavelength range, if produced by a filtered non-monochromatic source, which targets the lipids contained within the sebaceous gland, thus destroying the differentiated and mature sebocytes by photothermolysis without damage to the surrounding and overlying tissue or to the basement membrane of the sebaceous gland.
