Acne is caused by the presence of bacteria under the skin, and although there is no cure for acne; the use of phototherapy can considerably reduce the symptoms and provide you with a clearer skin. In most phototherapy treatments; blue, red, or a combination of both lights; is used to treat acne.
Why Is Blue Light Used For Acne Treatments?
The bacteria that cause acne, contains a substance that can easily absorb blue light. Once it has absorbed the light, it reacts with oxygen to reduce acne on the skin.
Why Is Red Light Used For Acne Treatments?
Red light penetrates deeper into the skin as compared to blue light, even though is it 10 times less effective. Red light is perfect for healing deep tissues and also contains anti-inflammatory properties that allow it to reduce swelling and redness of acne. Red light can boost the body’s healing processes, and is ideal for repairing wounds as well.
Why Should You Use Alternating Blue and Red Lights for the Treatment?
Blue light can kill bacteria, and red light can heal the skin. Thus, combining them together allows for a perfect treatment of acne, where both, surface, as well as deep skin tissues are healed and treated within a single session. VersaClear has easily changeable light modules, using alternating red and blue light therapies for acne is also quite simple and convenient.
Phototherapy Treatment Protocols for Acne
Light therapies are a long and ongoing process, requiring prep and care, before and after the therapy. The process includes:
2 Weeks Before: Application of topical ointments or skin peels to remove the top layer of the skin for better absorption of the light.
Immediately Before the Therapy: Skin cleansing to ensure that it is free from all makeup, pollutants, creams, and dead skin. A quick skin peel is also often performed.
During Therapy: For blue light alone; a 20-minute session; conducted twice per week, for 4 week to 6 weeks. For alternating red and blue lights; a 20-minute session of blue light, followed by a similar session of red light, twice per week, for 4 weeks to 6 weeks.
In Between Sessions: Use of topical solutions and skin cleansers to keep the skin free from bacteria and pollutants.
Effectiveness of Phototherapy for Acne
In most cases, the treatment shows an average of 60 to 80% improvement in acne, with the alternating treatment of blue and red lights being more effective than the treatment containing only blue lights.
