SkinMedica HA5 Rejuvenating Hydrator, 2 oz – 5 Types of Hyaluronic Acid Serum, Authentic

Smooth, hydrated skin depends on hyaluronic acid (HA) — a natural, "water-loving" molecule found in the skin that holds in moisture, keeping it healthy, resilient, and supple. As skin ages, its natural HA levels decline, diminishing its ability to stay hydrated. HA5 Rejuvenating Hydrator was the first hydrator of its kind designed to go beyond surface-level hydration to support overall epidermal health.

Unlike many topical HA serums that only temporarily hydrate the skin's surface, HA5 is powered by SkinMedica's exclusive VITISENSCE Technology — a proprietary formulation harnessing potent antioxidants found in Vitis (grape) flower stem cells and algae extracts to support the skin's own ability to replenish its natural hyaluronic acid. At the core of the formula is a proprietary blend of five distinct forms of hyaluronic acid, working synergistically to provide immediate smoothing alongside continuous, long-lasting hydration throughout the day — up to 8 hours, according to the brand.

HA5 provides immediate smoothing in the appearance of fine lines and wrinkles while improving overall skin quality, tone, and texture for a more hydrated, radiant, rejuvenated complexion. It's fragrance-free, suitable for all skin types, and designed to complement any existing skincare regimen focused on preventing and addressing visible signs of aging.
