Blue and red light have been found to have a positive effect on many skin conditions, but now attention is focusing on the role green wavelengths of light can play in treating mild to severe acne. A recent report in the Cosmetic Dermatology journal examines the use of photodynamic therapy using a green light laser, which involves the application of a light-sensitive agent before the treatment. Green light has already proven effective for treating spider veins and pigmented lesions.

The bottom line: Acne is often resistant to treatment; and the success of most over-the-counter and prescription treatments depend on regular and consistent use. Light and photodynamic therapies are attractive options because they are noninvasive, usually well tolerated and can treat many lesions in short sessions. While questions remain about the optimal light source, photodynamic therapy agent, number of treatments and other factors, green light is poised to present yet another acne treatment option. Initial findings show that green light has a positive effect for regulating bacterial and sebaceous gland activity that lead to acne, yet more studies are necessary to set the specific treatment guidelines.
