Acne is caused by bacteria that our skin comes into contact whenever we go out. The dirt, the grime and the very polluted air can cause acne breakouts. Sometimes, creams doesn’t get the job done. My dermatologist at one time treated my acne with the use of an acne light. Blue and red LED bulbs were used in combination to finally heal my acne. I must admit that I was very much impressed. So the next time you run into this problem, light therapy might just be what you need.
