“I have used this product twice. the first time I left it on for 5 minutes. Did not feel any kind of tingling. Second time, a week later, I left it on about 30 minutes. Still no tingling. I do not have any skin problems, just a couple brown spots. I will say that my skin has never felt so soft. Will keep using to see if brown spots disappear. Might work up to leaving on overnight.”
“I bought for clearing some dark spots. It is great and dried any pimple . Next day I used repair night cream, which is absolutely the best. My only complaint is price and very small amount. I have already recommended this product”
