Vitamin B5

Vitamin B5 is most often used in skincare as panthenol, a provitamin the skin converts to pantothenic acid. It acts as a humectant, replenishing moisture and supporting the skin's barrier, so skin feels softer, more supple and more comfortable. It is well tolerated by most skin types, including sensitive skin and skin prone to redness.

Vitamin B5 is a quiet constant across the iS Clinical range. In the Treat step it appears in Super Serum Advance+, Poly-Vitamin Serum, Hydra-Cool Serum, Youth Complex, Youth Eye Complex and NeckPerfect Complex. Moisturizing Complex and SHEALD Recovery Balm carry it into the Hydrate step, while Body Complex and Youth Body Serum extend it to the body. Whichever you choose, finish the morning with SPF.
