Pure. Natural. The Timeless Pure collection contains a high concentration of hyaluronic acid that you won't find anywhere else. All natural and paraben free, we don't use excess ingredients to make up for the lack of actives. We like to keep it simple and effective. Hyaluronic Acid - one of the most powerful hydrating and moisturizing ingredients on the market today. Holds up to 1000 times its weight in water! And as always, we use a higher concentration of HA than any other seller. This serum contains 1% HA, or about 2x the amount of HA contained in others 60% concoctions.
