Blue Light
What is acne? Acne is a skin disease characterized by areas of scaly red skin. The area affected will show signs of blackheads, whiteheads,
pinheads, pimples, nodules and scarring. Acne affects the part of the skin with the densest population of sebaceous follicles which
include the face, the chest and the back. Acne occurs as a result of blockages in follicles. Hyperkeratinization and formation of
a plug of keratin and sebum is the earliest change. Enlargement of sebaceous glands and an increase in sebum production occur with
increased androgen production at adrenarche. The microcomedo may enlarge to form an open blackhead or closed comedone.
Blue Light Treatment - Blue light therapy for acne is done by applying a photosensitizing agent to the surface of the skin, then
the skin is exposed to a narrow band, high intensity blue light. The blue light is the most used light therapy for acne treatment.
Blue light works by killing the acne causing bacteria P. acnes.
