This serum helped to firm up my skin. I was beginning to have very slight sagging at the jaw line. It is obviously not a face lift, but it firmed up my jaw enough that I noticed. It also has soothing qualities. I use at night w/ Retin-A and it helps to calm the irritation. When I use the serum w/ my Retin-A I don't get quite so red anymore. No fragrance too! I don't use in the morning as I've read copper and vitamin C when used together, cancel each other out. I was very pleased to get results with just once a day application.
