Panthenol (Pro-Vitamin B5)

Panthenol is the alcohol analogue of pantothenic acid (vitamin B5) and converts to it within the skin. As a humectant it binds water and improves hydration, while its documented wound-healing properties stimulate epithelialisation and fibroblast activity. Panthenol reduces transepidermal water loss, calms redness and irritation, and increases skin suppleness within days of use. At 2–5% it strengthens the barrier; at 5%+ in after-sun or post-procedure products it meaningfully accelerates recovery. It is non-irritating, pairs with every active, and is one of the few ingredients genuinely recommended for compromised, sensitive, or freshly exfoliated skin — a universal soothing booster.
