About

Panthenol, also known as Pro-Vitamin B5, is a moisture-binding and conditioning ingredient used across skincare and haircare. It is valued for its ability to improve softness, comfort and resilience without leaving skin or hair feeling heavy.

Science

Panthenol acts as a humectant, attracting water into the skin's outer layer to improve hydration. It also helps organize and support the moisture barrier, reducing the amount of water that escapes from the skin and helping preserve softness and elasticity. In hair, its small molecules can penetrate the fiber and form hydrogen bonds with hair proteins, helping increase tensile strength while leaving strands smoother and more flexible.

History

Panthenol has been used in topical skin preparations for more than 70 years. Over time, its established moisturizing and barrier-supporting properties made it a widely used ingredient in modern skincare, scalp care and conditioning hair treatments.

Origin

Panthenol is the lab-crafted provitamin form of pantothenic acid, or Vitamin B5. Its structure allows it to be incorporated into cosmetic formulas as a stable, water-compatible ingredient selected for skin hydration and hair conditioning.

Did You Know?

Panthenol does more than coat the outside of the hair. Research has shown that it can penetrate into the hair's inner cortical protein regions, where it forms interactions with hair proteins that help improve the strand's resistance to breakage.
