Panthenol (Provitamin B5)
INCI · Panthenol
Related names and forms: D-Panthenol · Pro-vitamin B5. This list does not indicate synonyms or exact ingredient matches.
Panthenol is a provitamin B5 ingredient used for moisture support. D-panthenol is also called dexpanthenol, and raw materials containing DL-panthenol also exist. Panthenol alone on a label does not confirm the isomer form or raw-material purity. Its role in skin and hair care needs product context. The glycerin and barrier-function pages below complement the distinction between humectancy and barrier measurements.
i. Cosmetic Functions
Frequently Discussed Effects
The following headings summarise areas of effect frequently discussed in the literature; visible results in each area require regular use and a suitable formula.
Moisture Support
It is used as a humectant in skin care.
Barrier Measurements
A controlled study of dexpanthenol formulas found increased hydration and reduced water loss.
Hair Care
Hair products also use it as a humectant care ingredient.
Mechanism
What Happens Within the Skin?
The following points summarise mechanisms from dermocosmetic literature in plain English. Klaris presents them as background information to help readers understand the context, not as medical claims.
Step 1
Provitamin Definition
D-panthenol is a precursor of pantothenic acid, or vitamin B5.
Step 2
Hydration and Water Loss
Water held in skin and water lost through it are measured separately.
Step 3
Form Distinction
Results obtained with dexpanthenol are not assumed identical for every raw-material form.
ii. Role in the Formula
How Is It Read on a Label?
A leave-on cream and a rinse-off hair product are different formulas. Skin studies do not establish hair growth or prevention of hair loss; product type and the measured outcome matter.
A Closer Look · pH, Stability, Synergy
Gehring and Gloor evaluated dexpanthenol in two lipophilic vehicles in a randomised, double-blind, placebo-controlled human study. After 7 days, hydration increased and transepidermal water loss decreased. These hydration and barrier findings concern specific vehicles, not all creams, shampoos or skin conditions. Supplier information on hair-care use should not be read as evidence of hair growth.
Typical Concentration Range
Varies with raw-material form and the finished product

iii. Sensitivity Advisory
A Note on Extra Care in Context
Do not equate cosmetic moisture support with treating wounds or skin disease. Stop use and consult a health professional if persistent irritation develops.
A sensitivity advisory is not an instruction for use; where individual health circumstances, pregnancy or known sensitivities are involved, discussing the decision with your doctor may be a more contextual approach.
Common Misconceptions
Frequently Confused Points
Common Belief
Panthenol cannot provide any moisture support itself.
A More Contextual Reading
Controlled dexpanthenol-formula studies have shown hydration support, interpreted with the formula.
Common Belief
Panthenol always means the pure D-form.
A More Contextual Reading
D and DL raw materials exist; the INCI name alone does not provide that detail.
Common Belief
A provitamin cosmetic corrects vitamin deficiency.
A More Contextual Reading
Cosmetic care is neither vitamin-deficiency treatment nor a nutritional supplement.
