Hyaluronic Acid 2% + B5

As listed: Sodium Hyaluronate

A glycosaminoglycan humectant that binds large amounts of water; high-molecular-weight forms sit on the surface as a hydrating film, low-molecular-weight forms penetrate the stratum corneum. Because it is a humectant, in dry air it can pull water from deeper skin — so apply to damp skin and seal it.

A small humectant that attracts and holds water in the stratum corneum, delivered into the epidermis partly via aquaporin-3. It raises hydration, improves plasticity and desquamation, and supports barrier recovery — one of the best-evidenced moisturizing agents.

As listed: Panthenol

The stable analog of vitamin B5, converted in skin to pantothenic acid. As a humectant it improves hydration and lowers water loss, while soothing irritation, reducing erythema, and supporting barrier repair and re-epithelialization.
