SkinCeuticals HA Intensifier Multi-Glycan Hyaluronic Serum is formulated to target the visible effects of declining glycosaminoglycan levels in the skin, which naturally reduce with age and contribute to loss of volume, elasticity and hydration. Pure hyaluronic acid works to attract and bind water within the skin, helping to instantly improve plumpness and smoothness. Proxylane™ supports the skin’s structural network, helping to improve firmness and definition over time. A post-biotic ferment helps stimulate glycosaminoglycan production, including hyaluronic acid, to support long-term hydration and skin density. This multi-action hyaluronic acid serum helps improve overall skin quality by increasing moisture retention and reinforcing the skin’s support matrix. Clinically, it is shown to enhance visible fullness, improve radiance and soften the appearance of fine lines, while delivering up to 24-hour hydration. Skin appears smoother, more lifted and better balanced with continued use. Choose your FREE 15ml serum from C E Ferulic, P-TIOX or HA Multi Glycan to complete your routine.
