I've been using Plexaderm for almost two years. I don't use it every day, but mostly when we go out to eat, attend church, etc. My eye bags are present under both eyes, but more so under the left eye. I thought maybe I'd get different results between the right and left, but that was not true. Plexaderm works equally well for the left eye bag, even though it is much more pronounced. I do follow the application instructions concerning the amount to be used for each eye. But another helpful lesson I learned is that I do not rub it "into" the skin like I would rub in a lotion. I simply spread the application evenly across the entire area of the eye bag, using soft pressure, and making sure I cover the area completely all the way down to skin crease where the eye bag meets the upper cheek. If I have applied the correct amount, there will be no visible residue when I have finished the application process. Then I refrain from smiling, speaking, etc while the application dries. That's it. My eye bags disappear completely. In most cases, Plexaderm holds for me at least five hours, longer if I'm not real active. The main thing to remember, I believe, is to spread the application softly and evenly, all the way down to the crease at the upper cheek, and refrain from trying to rub it "into" the skin as you would a skin lotion. Then allow it to dry undisturbed. Works for me, and it works very well.
