Yes, I believe in StriVectin. Where I've seen the most improvement is in my 79-year-old mother-in-law who was such a sun worshipper. She's not wrinkle free, but her skin is much, much better. She and I have used it for several years. I won't be without it.
I used their products ( ones like them from another company ) on a couple of stretch marks I had on my upper thigh. I loved the results. If they weren't so expensive, I've have all their products and I'd use them daily.
