Do they work? Are they harmful?
Am thinking of getting one for DS who has acne and a,though it’s better than it was using something called “SkinKissed Serum” he does have some scarring.
I’ve read that Blue LED works on reducing the actual acne whilst one of the other mask colours built in, works in the healing and scarring aspect.
Anyone have any experience of these things? When I go online there’s so many of them but...I’m dubious 😐
