As you’ve read, acne light therapy is effective for about 86% of people.  Why wouldn’t it work for everyone?  There are several possible reasons.

1. Blue light is effective against the acne bacteria p. acnes, not all acne is caused by that specific bacteria.

2. Some things that look like acne are not acne at all, for example, a yeast infection can look like acne.  Shining blue light on that could actually make the condition worse, because the blue light may be killing some of the bacteria that is trying to keep the yeast under control.

3. Light therapy works on a cellular level.  You’ve heard the expression, “You are what you eat.”  Everything you put into your body effects your body chemistry, and therefore your individual reaction to light.   At the LLLT Symposium last weekend (Aug 7&8, 2009) it was brought out that the presence of NSAID medication (Advil, Alieve and others) decreased the effectiveness of light in one study.  Effects of different medications was given as a reason why light therapy may be effective for some and not for others.

Even though acne light therapy does not work for everyone for various, valid reasons, it is effective for most people and is certainly worth a try.    Most acne light companies offer a 12 week trial period and offer a 100% satisfaction guarantee.
