I started using this product in hopes it would help with the under eye puffiness and discoloration. While it did seem to tighten the skin after application, as soon as I applied the remainder of my skin products, the effects were significantly lessened. There also was a white coating on the skin that would flake and appear wrinkled under makeup, etc.
While I was willing for the time to put up with the above, the experience that totally turned me off was when I was using the plunger to squirt the product onto my fingers for application and it misfired and sprayed my mirror. To my horror, the product actually ate away the outside layer of the mirror, and it is now "pocked." I can actually feel the missing layer. If it eats away something like glass, I can't imagine what it will do to my face over time! I plan to return the last three tubes I purchased and hope the company will reimburse me.
Bottom Line: No, I would not recommend this to a friend
