2PK Peter Thomas Roth Instant FIRMx Temp Face Tightener

USED ONCE. I AM RETURNING THIS. HERE'S WHAT YOU NEED TO KNOW. FOLLOW THE DIRECTIONS! Use a minimal amount. Allow it to dry 3-7 minutes. It takes up to 7 minutes to see the desired effect. Those stating here that it leaves a white residue have applied too much of the product. A tiny bit of this goes a long way. I had NO white residue. PROS: It does what it promises. While it doesn't get rid of dark circles under the eye, it DOES tighten the skin. When I put it around my "crow's feet", after about 6 minutes - those little lines disappeared. The skin under my eye became taught and smooth. HUGE CON (WHICH OVER TIME WILL AGE THE SKIN AROUND YOUR EYES): The delicate skin under my eye became INCREDIBLY, HUGELY, MONUMENTALLY - VISIBLY - DRY. This skin tightener works well, so long as you NEVER move your facial muscles. About a half hour after applying a tiny amount, my skin had indeed tightened. I held a mirror up to my face and smiled, and all of a sudden ALL OF THE SKIN UNDER MY EYES WAS NOTHING BUT TINY WRINKLES. That area of my face suddenly looked incredibly old and aged. I was about to go meet friends, so I tried to get rid of the dryness by applying a thin coating of under-eye moisturizing cream. Waited for that to sink in a bit, then did a tiny bit of powder to hide the blotches caused by the removal of the skin tightener. I cannot NOT recommend this enough. If you use it, just do not ever smile or move your facial muscles, and you'll do fine. It arrived yesterday. It is being sent back tomorrow. Bad, bad, bad. Please save your money.
