I am obsessed with this led body mask, I was using the face mask to do my whole body but it was taking forever so I invested in this, as it was of offer. It is easy to use, it bends and folds so you can bend it around shoulder, hips ect. It had a long battery life, I love the longer timed setting for pain, it seems to help my arthritic knee. This led light it has made my skin look better and I believe it has improved the appearance of a scar! It’s a very pampering at home treatment and I look forward to seeing long term results. It has a red light for anti aging, a blue light for acne and a third setting to use both lights together. It is on a timer too so you can just relax.
