Let's face it. As we age, we lose the ability to produce all the collagen our bodies need function well and retain youthfulness. We can't turn back the hands of time, but with this product one can put will look more youthful trying. I've used this product for several years and I'm never disappointed. True to its label, it actually replenishes collagen anywhere in the body where it's needed. In our face, hair and other areas where it's needed. Try as I might, I have never over dosed. I highly recommend to anyone who could use that extra touch of inner “plumpness” to counteract normal aging.
