With the popularity of using controlled light therapy for acne on the rise as a safe and effective alternative to costly and painful procedures, many companies are coming out with handheld light devices in red or blue, about the size of a lipstick case.

A way to speedily boost acne healing is to supplement vitamin D and A (Accutane is concentrated vitamin A after all)!
