HA5 Rejuvenating Hydrator

The SkinMedica HA5 Rejuvenating Hydrator is a top selling, luxury, medical-grade hyaluronic acid serum that delivers oil-free hydration, smooths fine lines, and boosts your routine's effectiveness. Its advanced formula features five distinct forms of hyaluronic acid (HA), each imparting multiple benefits. The tiniest HA molecules penetrate the skin and bind water, restoring plumpness and volume from within, while larger HA particles sit on the skin’s surface, acting as a humectant to attract moisture to the skin's surface and visibly reduce the appearance of fine lines. This gives your skin the dewy, "glass skin" finish that is all the rage right now. This multi-level hydration keeps skin smooth, soft, glowing and radiant all day long.

With a combination of time-released and fast-acting HA forms, this hydrator offers both immediate skin benefits. It improves moisture retention and enhances the absorption and performance of other products in your skincare routine when used in the correct routine step. By maintaining optimal hydration levels, the SkinMedica HA5 Rejuvenating Hydrator prepares your skin to absorb serums and creams more effectively, boosting their overall results.

This lightweight, silky formula is suitable for all skin types, including sensitive, dry, oily, and acne-prone skin. If you have dry skin, this should be used in combination with a barrier repair moisturizer. Oily skin types can use this under sunscreen.

This product is paraben-free, fragrance-free, and oil-free but contains dimethicone.
