Panthenol
Provitamin B5 — humectant and comfort active
Function in skin biology
Panthenol (D-Panthenol, provitamin B5) is converted to pantothenic acid in skin tissue. In cosmetic research, it has been evaluated for its capacity to support hydration retention, help improve the sensation of skin comfort and contribute to formula tolerance in sensitive skin contexts. It is a well-characterised cosmetic active with a long safety record across skin types.
Why Ambernay uses it
Panthenol is selected for Ambernay formulas where the objective requires a combination of humectancy and comfort — particularly in formulas designed for daily use on reactive or barrier-compromised skin. It contributes to the feel of the formula and to the tolerance profile, not only to a single function claim.
Where concentration matters
Panthenol is effective across a moderate concentration range, typically 0.5–5% in leave-on cosmetic formulas. At functional concentrations it contributes to measurable water retention improvements. It does not require high concentrations to deliver cosmetic benefit and is one of the more forgiving actives in terms of formula compatibility.
What we do not claim
We do not claim that panthenol heals, treats or repairs skin. We do not claim it treats wounds, burns or skin conditions. Panthenol in a cosmetic formula is evaluated as a cosmetic humectant and comfort active — not as a pharmaceutical or medical-grade intervention.
Used in Ambernay products
- Hydra-Calm Moisturizer — comfort and hydration context
- Hydra-Rich Moisturizer — hydration architecture
Best paired with
Panthenol works well alongside glycerin (layered humectancy), ceramides (barrier context), niacinamide (tolerance context) and emollients such as squalane. It does not conflict with UV filters and is suitable for use in multi-active daily formulas.
Claim caution / regulatory note
Panthenol is a cosmetic ingredient. Claims must remain within cosmetic function: hydration, comfort, feel, visible improvement in appearance. Wound-healing, scar treatment or dermatological repair claims are not permissible in a cosmetic context and have not been substantiated to the standard required for a medicinal claim.
