I started using Stryvectin when it first became known for faces instead of stretch marks (10 years ago). I saw improvement within a few days and I haven't stopped using it since. I am 63, but my skin says 40 something. You might need additional moisturizer, but stick with this. No matter what any article says, this is the best thing out there, and though expensive - it's a big tube that lasts a long time. My husband uses it faithfully, too and he's 67! One hint (this goes for other "tube" products, too): when the tube seems empty, squeeze like a toothpaste tube, then cut in two at the middle. If any remains in the bottom half, just scoop it and move to top half. use the bottom half to fit over the top as closure until you've used every bit. You'll get at least an extra week from an expensive product! I do this with ALL pricey tubes. They really package things so you can't use it all without extra effort. Same thing with pump tops - when they seem empty, the little tube NEVER reaches to the bottom. Take it out, replace lid with a screw top and turn upside down - lots will be left.
