Does this work? Nooooooooo! I LOVE Benefit's Skincare Collection (currently using and loving it), but I have NO LOVE for their Instant Comeback Facial Serum. It comes in a pretty bottle, applies beautifully, but that is where the magic stops. Once applied, it feels heavy & sticky on the skin. Not a good feeling. It doesn't blend or work well with makeup. So you can't use it during the day. It's suppose to plump, hydrate, firm, smooth and energize tired skin. It didn't for me! I've tried this both morning & night since December and nada (nothing). No miracles. No comeback. No bounce back. No fountain of youth. No genie in a bottle. Save your money. Do you use serums? Any recommendations?
