KEY INGREDIENTS

Multi-Weight Hyaluronic Acid

Unlike many other hyaluronic acid serums, Hydr8 B5 uses multiple molecular weights of hyaluronic acid (small, medium and large), to distribute deep hydration evenly throughout the skin's many layers. This leaves the complexion visibly nourished and supple.
Vitamin B5

Also known as panthenol, vitamin B5 helps the skin to retain and regenerate moisture for visibly plumper skin.
