Panthenol (Vitamin B5)
Panthenol
INCIPanthenol, D-Panthenol, DL-Panthenol, Calcium Pantothenate, Provitamin B5
The small molecule that quietly does three jobs: humectant, anti inflammatory, barrier supporter. The reason your favourite calming cream never irritates. Underrated even by the people who use it daily.
What you need to know
What it is
The alcohol form of pantothenic acid (vitamin B5). Once on the skin, it converts to pantothenic acid. Small molecule, penetrates easily, very well tolerated. Used in skincare, haircare, baby care, and prescription wound healing creams.
What it does
Three jobs in one molecule. Humectant: pulls water into the upper skin layers. Anti inflammatory: calms redness and itch. Barrier support: stimulates keratinocyte proliferation and skin repair signalling. Quietly effective without drama.
Best for
Dry, sensitive, irritated, or recovering skin. Post procedure use. Atopic dermatitis. Hair conditioning where it adds slip and temporary thickness. Universally compatible with other actives.
Time to results
Comfort and reduced itch: within hours. Visible calming of redness: a few days. Sustained barrier support: two to four weeks of consistent use.
How it actually works
Panthenol is unusual because it covers three distinct mechanisms in a single small molecule.
Humectant
Hygroscopic small molecule. Pulls water from the dermis and the air into the stratum corneum. Less heavy than glycerin, less sticky than HA, sits well in light formulas.
Anti inflammatory
Reduces inflammatory cytokine activity in the upper skin layers. The mechanism is not fully mapped but the effect is measurable in atopic and post procedure studies. Reduces itch, redness, and stinging.
Wound healing
Stimulates keratinocyte proliferation and supports skin repair signalling. The reason panthenol shows up in prescription wound healing creams (Bepanthen and equivalents) used after burns, tattoos, and surgical incisions.
Hair binding
Penetrates the hair shaft and binds keratin. Adds slip during combing, temporary visual thickness, and surface conditioning. The reason panthenol is in nearly every conditioner and leave on hair treatment.
What the clinical data shows
Panthenol has a long evidence base across atopic dermatitis, wound healing, post procedure recovery, and barrier support.
Reduced itch and dryness in pediatric and adult studies of 5% dexpanthenol creams (Camargo 2018 review)
Faster healing and reduced erythema after laser, microneedling and tattoo procedures in multiple controlled studies
Significant reduction in transepidermal water loss in 4 to 8 week studies of 5% panthenol formulations
Across all studied populations. Used in prescription wound care, baby creams, and nipple creams. Among the gentlest cosmetic actives.
Panthenol vs the alternatives
Both are humectants. HA gives more surface plumping. Panthenol penetrates more easily and adds anti inflammatory action. Layer them. They are not interchangeable.
Both calm reactive skin. Centella has stronger collagen building data. Panthenol acts faster on itch and tightness. They are often paired in post procedure creams for fast comfort and longer term rebuild.
Ceramides patch the lipid barrier from the structural side. Panthenol supports the cells building the barrier and adds humectant water binding. Different jobs, both belong in a barrier focused routine.
Both are humectants. Glycerin is cheaper and a more reliable surface humectant. Panthenol penetrates better and adds inflammation and wound healing effects. Well formulated products use both.
Both are gentle keratin softeners. Allantoin is cheaper and slightly milder. Panthenol does more (wound healing, humectant). For premium positioning, panthenol is the stronger pick.

Is panthenol the same as vitamin B5?
Almost. Panthenol is the stable alcohol form of pantothenic acid (vitamin B5). Once absorbed into the skin, it converts to pantothenic acid. The cosmetic form is panthenol because pantothenic acid is sticky and harder to formulate with.
What is dexpanthenol?
Same molecule, the d isomer specifically (the biologically active form). DL panthenol is a mix of d and l isomers. D panthenol is more active per gram. For cosmetic use the difference is small. Prescription wound healing products typically specify dexpanthenol.
Does panthenol grow hair?
It does not stimulate new hair growth. It binds to existing hair shafts, adds temporary visual thickness and shine, and conditions the cuticle. Marketing claims about hair growth from panthenol overstate the cosmetic effect.
Can I use panthenol on broken skin?
Yes, this is one of its strongest uses. Panthenol containing wound healing creams (Bepanthen and equivalents) are used after burns, tattoos, microneedling, and minor surgical procedures. The wound healing evidence is well established.
Why is panthenol in so many baby products?
Because it is unusually well tolerated by very young skin and helps with the typical issues (nappy rash, dryness, mild eczema). The same properties make it useful in adult products too.
How much panthenol should a product contain?
Cosmetic ranges from 1 to 5%. Above 5% you start to feel a slightly tacky surface. Prescription wound healing concentrations are typically 5%. Look for panthenol within the first half of the INCI for a formula that is doing real work.
