5 Things You Need to Know About Phototherapy for Acne

1. Phototherapy for Acne: Green and Red Lights

Just about the time we realize that ultraviolet light is not good for the skin, along comes phototherapy for acne. Phototherapy outfitted with Light Heat Energy (LHE) technology works by exposing the affected skin to ultraviolet light B (UVB). Essentially, it's all about the green and red light that is present in UVB. The green lights are capable of reaching down deep, under the surface of the skin. This is where bacteria that are responsible for acne grow, and the green light kills them. Meanwhile, the red lights work by eliminating T cells, thereby decreasing inflammation. Heat is also a factor in phototherapy, as it opens and exfoliates pores, unclogging them.

2. Narrowband Versus Broadband Phototherapy

Broadband therapy has been around a long time, but not for acne treatment. It has been extremely effective for other skin conditions, such as psoriasis. The downside is that you will need to receive phototherapy three to five times per week for acne, so time and the expense of driving add up. Narrowband phototherapy is newer; only time will tell if it really is more effective than broadband. Narrowband phototherapy is capable of causing burns, sometimes severe. Experts do not know if UVB treatments can cause skin cancer in the long-term.

3. The Doctor Knows Best

Anyone considering phototherapy as an acne treatment should consult a dermatologist. You can expect each treatment to last about 30 minutes, but don't expect one acne treatment to be a magic wand. Generally, 8 treatments equal a cycle. Talk to your doctor about your goals compared to realistic expectations. Ask him about any side effects. Most importantly, ask him for his opinion as to whether phototherapy for acne is the right treatment for you.

4. The Pros, Cons and Unknowns of Phototherapy

Check with your insurance company because it may not cover phototherapy for acne as opposed to prescription acne medications, which generally are covered. The cost varies, but you can expect to pay $100 to $120 per treatment. Multiply that by eight treatments, and you get the picture. The good news is that most people see results with their first treatment. In addition, most people will see about a 90 percent improvement in their acne after one cycle (eight treatments). The bad news is that scientists cannot say how long the treatments will last or if follow-up maintenance is required.

5. Phototherapy for Acne at Home

You can purchase phototherapy lights for home. However, you should speak to your dermatologist about whether phototherapy for acne treatment, especially at home, is appropriate for you. The lights can be expensive, and your doctor can explain to you the difference between lights for home use and those in an office setting. Then you can make an educated decision.
