What is it doing: It is pantothenic acid, the alcohol form of vitamin B. It is also sometimes called pro-vitamin B5 or D-Panthenol. It is used in premium skincare like Pour Moi, as a humectant because of its ability to attract and retain water by building a thin moisture film on the surface of skin. Studies have shown its moisturizing properties improve stratum corneum hydration, reducing Transepidermal Water Loss (TEWL) and maintaining skin elasticity and softness.
