With a silky consistency and a dewy, plumping finish, the ever-so-lightweight Hy-Gen Skin Glass Primer Serum nourishes skin with 72 hours (!) of hydration and softness, while bestowing a gorgeous gleam that leaves skin luminous, under make up or when worn alone. That's thanks to crystal-like ultra-fine reflecting pigments which give a 'lit-from-within' glow. And for the hydration, you can thank the 'Skin Thirst Relief Complex' which uses a blend of hyaluronic acid, natural moisturising sugars, and powerful humectants to not only offer short-term moisture, but also strengthens your skin's natural ability to regulate its own hydration levels over time. And for a stronger, healthier moisture barrier, there's also Mediterranean microalgae.
