Panthenol (Pro-Vitamin B5)

aka pro-vitamin b5 · d-panthenol · dexpanthenol · vitamin b5

Vitamin B5 in its skin-penetrating alcohol form — converts to pantothenic acid in the stratum corneum. The barrier-repair and humectant defaults of dermatology, anchoring everything from Bepanthen (the Bayer wound cream) to La Roche-Posay Cicaplast B5 to virtually every K-beauty 'B5' product (Some By Mi B5, Numbuzin, Torriden DIVE-IN). 2024–2025 saw 'B5' become the calmest possible marketing claim — universally readable as 'this won't hurt'.

Benefits
  • humectant — binds water in the stratum corneum
  • supports barrier repair and re-epithelialization
  • soothes redness and sensitivity
Example uses
  • barrier-repair creams (LRP Cicaplast)
  • post-procedure care
  • scalp and hair leave-ins
Formulation notes

Effective at 1–5% in leave-on; 5% is the LRP Cicaplast hero dose. Stable across pH and temperature, compatible with everything. Use D-panthenol (the active enantiomer) not racemic DL-panthenol.

Watchouts

Allergic contact dermatitis is rare but documented.
