Panthenol
INCI · Panthenol · also pro-vitamin B5, dexpanthenol
How it works
Panthenol is a provitamin that converts to pantothenic acid, or vitamin B5, once absorbed into the skin. It acts as a humectant, drawing and holding water in the stratum corneum, while also supporting the skin's natural lipid synthesis and reducing transepidermal water loss. Its dual hydrating and repairing action is why it appears in everything from lip balms to post-sun recovery creams, and why it is a near-universal supporting ingredient across cosmetic categories rather than a niche specialty active.
The evidence
Panthenol has a long-standing, well-documented record for improving skin hydration, reducing irritation, and supporting wound healing, both in dermatologic and cosmetic research. It is one of the ingredients I feel most confident recommending broadly — the safety and efficacy data are consistent and span decades of clinical and consumer use, with dexpanthenol specifically used in medical settings for burns and post-surgical skin care long before it became a skincare marketing term.
Suitability
- Suitable for every skin type, including acne-prone and sensitive skin
- Especially valuable for dry, dehydrated, or barrier-compromised skin
- Frequently used in soothing formulas after sun exposure or in-office procedures
- Considered safe during pregnancy and breastfeeding
Concentration
Panthenol is typically formulated between 1% and 5%, with 2-5% common in dedicated barrier-repair creams and moisturizers. It remains gentle and effective across this entire range, with no notable irritation risk at the higher end, which makes it one of the few actives where formulators have real flexibility.
Conflicts & combinations
- Pairs naturally with allantoin and beta-glucan for a calming, barrier-support stack
- Complements hyaluronic acid and ceramides in hydrating moisturizers
- No known conflicts with acids, retinoids, or vitamin C — commonly included specifically to buffer their irritation
- A safe daily-use ingredient for essentially any routine, at any stage of active introduction
- dryness
- redness
- uneven texture
