I have been using this products for more than 3 months and my skin changed completely to the better. I have hyper sensitive skinnand get irritation even from baby products or pharmaceutical products but perricone is the only brand that i do not get any irritations on my skin. It actually helpy skin barrier and helps with over all skin problems. I look younger more fresh my pores are not there anymore snd my discolorstion is better! I really recommend these products ive tried every brand on the market prom most expensive to cheap and this one rly is the best! Its the only vrand im buying second time the products.
