Panthenol (Vitamin B5): The Quiet Barrier and Hydration Helper
Share
Panthenol, the provitamin form of vitamin B5, shows up in moisturisers, serums and after-shave and after-sun products. It rarely gets attention, but it has a long track record.
What panthenol does
On the skin, panthenol converts to pantothenic acid (vitamin B5). It works as a humectant, drawing in water, and is associated with soothing and barrier support.
What the research says
A review marking the long history of topical dexpanthenol describes its use in skin care for decades, with evidence for supporting skin barrier repair and hydration and calming irritation (Proksch et al., 2017, PMID 28503966). More recent work has examined dexpanthenol as a helpful adjunct in dry, sensitive conditions such as atopic dermatitis (Gorski et al., 2022, PMID 35887707).
How to use it
- Look for panthenol in hydrating serums and moisturisers, often alongside hyaluronic acid.
- It suits sensitive and compromised skin thanks to its soothing profile.
- It layers well under a richer cream that seals hydration in.
