I'm over 40 and have taken great care of my face/neck skin, so a lot of these miracle wrinkle products have not impressed me. Purchased Strivectin after two separate cosmeticians recommended it for my eye area. After using per instructions for 4 months, some areas of my neck and face actually begain to experience minor sagging. Body stretch marks had no noticeable improvement. Because of the sagging, I switched to L'Oreal Age Perfect creams for one month now and the sagging has noticeably improved. The remaining Strivectin went into the garbage as it only had a one month guarantee.
