Ive been using this product every day for the last two weeks both morning and night and I am definitely seeing an improvement in color and tone as well as with my monthly hormonal breakouts of cystic acne in my chin. The month prior to buying this product I had 4 cystic pimples on my chin. This month I had just 1 and in using this device it shrunk down and dissipated within a weeks time which is nothing compared to my prior breakouts that would last weeks and weeks. I have a lot of scars on my chin and elsewhere on my face so I know it will take awhile for those discolored areas to even out a bit more but this product has truly given me so much hope. I used to get light treatments when I would go to get facials but cant afford facials as much as I would like. This device is well worth the money and it has truly become a relaxing ritual that Ive made part of my day. Highly recommend!
