It really works! It is simple to use - just plug it in, hold it over your skin, feel the gentle warmth for a few minutes and within days you will begin to notice a difference. No complicated instructions. Light covers a 2 and a half inch area at a time. I have large forehead 'worry' lines and large pores, this light helped diminish both and firm my skin within a week of daily use. No creams, conductive gels or toners required. It is quite bright - takes some getting used to if you are light sensitive. I also have the Acne Light and love them both.
