@nony - Light therapy is not that new. I know a teenager who had a horrendous breakout of acne on her skin.
She didn’t want to see a doctor but a friend bought her this acne blue light therapy device. She was told to use it for at least ten to twenty minutes a day.
Getting a teenager to sit still for twenty minutes is tough in itself, but she managed. After about a week the results were incredible.
A good deal of the acne had started to fade away. The device works by killing the bacteria which cause the acne. I think it opens up pores too so that your skin can breathe.
She never had to use another cream or ointment again. Within a few months her skin was totally clear.
