In my search for an LED light therapy mask, I landed on this one! I compared the big brands light output (and color light variety) and coverage and this one checks all the boxes. I use it for my hyperpigmentation/melasma and to increase collagen and fight all the nasty signs of aging. My teen even uses it to treat breakouts. This mask does it all!
