Hyaluronic Acid 2% + B5 (with Ceramides) serum is an updated version of our original formulation. This second-generation formulation combines ingredients for enhanced hydration, barrier support, and smoother skin. The addition of ceramides provides barrier support while retaining multi-depth hydration benefits. Key Features Advanced, multi-layer hydration: This hyaluronic acid serum features low-, medium-, and high-molecular-weight hyaluronic acid, a hyaluronic acid crosspolymer, and hydrolyzed hyaluronic acid. These 5 types of hyaluronic acid work together to hydrate the surface of the skin at multiple levels, re-plumping dry, dehydrated areas and improving suppleness. Barrier support with ceramides: Ceramides, a natural lipid found in the skin, lock in water while strengthening the skin’s moisture barrier. This formulation includes ceramides to ensure long-term hydration and help protect the skin from environmental stressors. Pro-vitamin B5 (panthenol): Supports the production of ceramides and fatty acids to further support the skin barrier. Panthenol also enhances the skin’s ability to retain moisture. Lightweight, non-tacky texture: This second-generation hyaluronic acid serum absorbs quickly and dries to a non-tacky finish, making it suitable for layering with other skincare products.
