I started using the Dermalogica Lip Renewal Complex about three years ago. My lips were always chapped and dry. After the first week of using this product my lips felt young and rejuvinated. I don't ever need to use anything else for my lips again. It filled in the lines and keeps them plump and juicy. When I go out, I wear it under my favorite lip gloss and I am ready to go! I will never leave the house with out it, even when I go to the beach!!!!!
