I have tried many products within the last four years, mostly with DMAE and vitamin C (ester-c). I recently bought Reviva's Peptides & More Anti-Wrinkle Cream. Within 2 days I noticed a difference in the smoothness of my skin, and also many fine wrinkle lines disappeared. I applied it at night, and when I woke up, my face felt incredibly different and smooth. I highly recommend this product. I feel it is the best anti-wrinkle cream on the market today, without reservations!
