Hyaluronic acid & radish root create a deeply hydrating serum to boost, plump & REJUVENATE skin with the ability to scientifically hold 1000 times its weight in water. Hyaluronic acid is a naturally occurring sugar found in our skin but just like collagen and elastin, the amount of naturally occurring hyaluronic acid in our bodies decreases as we get older. Eating fruits and veggies with lots of antioxidants helps retain it but for an extra boost, REJUVENATE is here to help! This is a wonderful little number to incorporate into your routine for dry or mature skin. NOTE - Most commonly Hyaluronic acid is animal-extracted (typically rooster combs) but the Hyaluronic acid in this serum is created from a fermentation process using glucose produced from corn.
