Reverse by CSM is a unique facial serum packed with natural ingredients and a citrusy scent. It's designed as an anti-wrinkle, anti-aging serum that tightens, tones, and evens out skin tone. So far, the serum has lived up to that claim on my skin, but please be aware that the heading on this item's description page misstates that it is an eye serum. This bottle is the face serum, NOT the eye serum so do not buy it to use as an eye serum! In other places on the page, the ingredients and description accurately refer to the skin serum, and the actual bottle indicates that it's a face serum. If CMS offers an eye serum, which it undoubtedly does, this is not it. Anyway, I'm quite happy with the serum and other reviewers, even long-time users, seem to agree. Serums are really invaluable in treating wrinkles and smoothing skin quite well, but continued results require ongoing use..
