The Innovation Behind Saro De Rúe Our freeze-dried technology removes all moisture in the process, eliminating the need for any preservatives or additives. The result, a single-use tablet that is 98.5% highly concentrated hyaluronic acid with a touch of squalene and Vitamin E for moisturizing effects. Pure and potent, these ingredients are preserved so that each waterless tablet is in its freshest form until re-activated with use by the Pure Activator. - Long-lasting Hydration- A one-time application provides long-lasting hydration for over 72 hours and does not wash off, giving your clients real results that last. - Medical Grade Hyaluronic Acid- Originally patented to reduce healing time in surgical procedures, application ensures your patients’ recovery time will be cut in half. - Low Molecular Weight- Our molecular weight is small enough to penetrate deeply into the epidermis, yet large enough to still attract 1,000 times its weight in water for an immediate plumping effect.
