Brand new, unopened. During the course of your lifetime, 25 types of collagen work with elastin to give your skin its youthful appearance. Collagen holds many times its weight in moisture, which is why younger skin looks firm and smooth. As we age, the body stops producing collagen and elastin. Pollution, smoking, and over exposure to the sun produce free radicals, or unstable molecules that cause damage to the skin, accelerating the aging process. The aging process only slows the production of collagen, but free radicals actively destroy it. Face products such as Dynamic Collagen Cream contains ingredients that speed up collagen production and fight free radicals. Dynamic Collagen Cream penetrates deeply to rebuild damaged cells, reconstructs the skin to make it smooth, supple, and clear. Crossposted to Mercari.
