What it is

Panthenol is a pro-vitamin form of vitamin B5. In Korean skincare it often appears in "barrier," "cica," and "derma" formulas because it hydrates without feeling aggressive.

What it does

It acts as a humectant while also helping skin feel calmer and more resilient. That makes it useful after over-cleansing, exfoliation, retinoids, cold weather, or any stretch where the skin barrier feels thin and fussy.

How to use it

Use panthenol in a toner, serum, cream, or sleeping mask. It pairs beautifully with ceramides, glycerin, centella, madecassoside, and niacinamide.

Good to know

Generally gentle and beginner-friendly. If a panthenol product stings, the issue is more likely the overall formula or a compromised barrier.
