In Victorian times, pretty, unwed girls were encouraged to never smile: for fear of causing wrinkles. Thankfully, we’ve since progressed and now have ample access to good skin care, like RoC’s Retin-Ox Correxion Daily Anti-Wrinkle Moisturizer, to help fight the aging battle for us. (Feel free to smile about this fact all you like.) According to the scientists at RoC, this facial moisturizer is a killer combination of retinol, to accelerate cell renewal; hyaluronic acid, to help retain water; and biopeptide, to stimulate your skin’s tissue repair. In fact, these brainy experts are so confident about the efficacy of their product, they’ll even tell you that if you use it, your skin will look ten years younger. And that is definitely something to grin about.
