Nu Skin reviews and discussion

I bought the Nu Skin toothpaste called AP24 based on a friend’s recommendation. I bought it off Amazon because they have free returns. I have seen no difference in the appearance of my teeth and I’ve been using it for 25 days. I tried to return it to Amazon and it said I had to contact the company. I called the company and the number was changed. I tried live chat and they refused to give me a refund because they don’t honor third party sellers. Scam! Don’t waste your money! One tube costs $25!
