Acne plagues many of us from our early teenage years to late adulthood. Now there is a new treatment that can truly shine light and clear your skin. The AC Dual treatment from the Venus Versa (Venus Concepts) uses a combined red light and blue light wavelength to treat active acne. It is a non-invasive procedure that uses light in the blue wavelength range of 405-420 nm to kill the Propionibacterium acnes or P. acnes bacteria in the skin.
WHAT DOES THE RED LIGHT DO?
The red light treatment penetrates deeper (630-940 nm) but is less effective at killing bacteria. Red light also causes the release of molecules that produce new blood vessels and collagen, which aid in healing.
WHAT DOES THE BLUE LIGHT DO?
The bacteria in acne release porphyrins. These are naturally occurring substances in the body (They also arise during the synthesis of hemoglobin in red blood cells). When porphyrins absorb light of certain wavelengths, free radical damage is produced, and this destroys the bacteria. The blue light acne treatment uses a narrow-band, high-intensity blue light source that is readily absorbed by porphyrins released by the bacteria causing acne. This improves epidermal turnover and sebum outflow. Several small studies have shown that blue light acne treatment appears to improve acne vulgaris with a reduction in inflammation and the number of pustules and papules in some individuals.
IS IT FDA-APPROVED?
This photodynamic therapy is FDA-approved for the treatment of moderate acne vulgaris or acne vulgaris that has not responded to other acne therapies.
WHERE CAN I GET THIS TREATMENT?
Dr. Rosenberg can administer the light acne treatment in his Beverly Hills office. The procedure takes about 10 minutes. Generally, 2 sessions per week over a 4-week period is all that is required. Some light delivery systems can be purchased and self-administered at home, but they are often not very powerful, and a physician should oversee their use.
ARE THERE ANY SIDE EFFECTS?
Side effects are generally minor and include:
• Swelling of the treated areas and dryness
• Temporary pigment changes
