Nikki, I would suggest your client start using Hydropeptide's toner with skin brightners and lactic gel. It works! However takes awhile so in the meantime suggest a good cover up. They can go to a good make up counter and ask for help for a good product. I have read about a type of edible mushroom also can help with this problem. Do a google search on benefits of mushrooms for pigmentation problems. I have the information from a publication on skin problems some place on file but can't find it. Sorry! Sayra
