The major bacterial cause of acne, Propionibacterium Acnes, can be destroyed by the application of light. n addition, infrared wavelengths (greater than ~750nm) penetrate more deeply into the skin, heating the overactive sebaceous glands and reducing sebum output. It is thought that reversible thermal damage to sebaceous glands can result in long term remission from acne. Gentle heating of the skin promotes fibroblast activity and stimulates collagen which may reduce mild acne scarring and accelerate the healing process. Broadband light sources such as the LUMINA are the only systems that can offer shorter wavelengths for optimum surface bacterial destruction, whilst also getting to the deep- seated bacteria existing in pustules and papules and targeting the sebaceous glands themselves.
