I have used Plexaderm for over a year now. I have also used other products costing as much as $200 and Plexaderm works as well or better. I especially like the new serum version. Plexaderm works so well it can actually pull your lower eyelid down if applied to heavily. Of course you don't want to have that happen. To ease the tightness I have found moistening my finger or a Q-Tip with baby oil will lessen it without taking all of it away. You then dab the lower eye area with a tissue. It also works for removing white residue that can occur. I find this better than the recommended water. The real trick is making sure your eye area is clean and dry. I use Plexaderm every day and love it.
