I must admit I was very skeptical about trying this product. I originally ordered this a few years ago when a little extra weight gain caused a few wrinkles around my eyes and the wrinkles in my forehead looked a little deeper. From the first time I used Serious Skin Care, I was amazed at how fast it worked, how my wrinkles literally disappeared and how smooth my skin looked after putting on my makeup. My face tightened up in every area where I used Serious Skin Care and it just worked fabulously. I will say that you need to be careful and not over apply it or put on too much product on or it will leave a white residue. Don't worry though if you put too much on, it's easy to fix - just gently blot the area with a lightly damp q- tip or your finger and the residue will go away. If you get the area too wet though, you will remove the product. In summary, as long as you apply it properly, it works great and that is true with any makeup product so this should be nothing new to those of you who use makeup. I have now been a Serious Skin Care user for several years and I LOVE it! I think it is a great product and I wouldn't do without it !
