I have dermal melasma from hypothyroid disease. I have had some success with having QSwitch laser treatments in the past. I also use lightening products, Vitamin C , Vitamin A and tretinoin creams. I wanted to see if either one of OTC products (LED or DermaWand) would help with my at home treatment. This condition is causing me to feel very down. Any suggestions I would be very grateful. Thank you in advance for your help.
