Panthenol is a good fit for most skin types. It is a provitamin of B5 that hydrates, softens and helps support the skin barrier. It turns into vitamin B5 (pantothenic acid) once it is on the skin, and it works as both a humectant and an emollient, according to Cleveland Clinic. It shows up in serums, moisturizers, masks and toners. This guide covers what it does, what studies show, how it compares with hyaluronic acid, and how to use it.
TL;DR
- Panthenol converts to vitamin B5 on the skin. It draws water into the surface layer and softens dry patches.
- Studies point to better hydration, lower transepidermal water loss and calmer irritated skin.
- Panthenol and hyaluronic acid are both humectants. They can be used together.
- Panthenol is generally well tolerated. Patch test any new product.
- Use it in a serum under a richer moisturizer, or in the moisturizer itself.

What panthenol is and how it works
Panthenol is the alcohol form of vitamin B5. Formulators use it because it is stable and mixes well into water-based products. You may also see it listed as dexpanthenol, D-panthenol or provitamin B5 on an ingredient label.
On the skin it does two jobs, as Cleveland Clinic describes:
- Humectant: it draws water up from lower levels of the skin to hydrate the epidermis.
- Emollient: it fills in dry patches so skin and hair feel smoother and softer.
This dual action is why panthenol appears in so many different product types. It adds water and it helps keep skin feeling supple.
Humectants, emollients and occlusives
Skincare ingredients that hydrate fall into three groups. Humectants pull in water. Emollients smooth and soften. Occlusives seal the surface. Dr. Taylor Bullock, quoted by Cleveland Clinic, says these groups usually work best together, and that a product or routine should contain ingredients from all three (source). Panthenol covers the first two. Pairing it with an oil or butter-based step covers the third.
Our guide to moisturizing versus hydrating explains the difference in more detail.
Benefits of panthenol for skin
Hydration
Hydration is the best-supported benefit. A 2019 study of semisolid formulations containing 7 to 11 wt% panthenol found significantly higher skin hydration and lower transepidermal water loss over 48 hours in 40 women. The authors concluded that panthenol supports barrier repair and hydration of the stratum corneum (PubMed).
A 2026 randomized split-leg trial tested a formula with panthenol, niacinamide and dipotassium glycyrrhizate on people with xerosis (very dry skin). Applied twice daily for 28 days, it raised corneometric hydration by 74.1% and lowered transepidermal water loss by 13.5% against baseline and untreated control (PubMed). The result applies to that full formula, not to panthenol alone.
Barrier support
The skin barrier is the outer layer that holds water in and keeps irritants out. Panthenol is studied for this role. A review of topical dexpanthenol in skin disorders reports effects on wound healing, inflammation and barrier function (PubMed).
Cosmetic Science rates the overall evidence confidence for panthenol as moderate, with hydration and barrier outcomes the strongest categories. It cites a controlled trial in which formulas with 1.0% and 5.0% panthenol produced significant drops in transepidermal water loss after 30 days (Cosmetic Science).
Soothing
The same dexpanthenol review notes an anti-inflammatory effect on experimental UV-induced redness and an improvement in symptoms of skin irritation (PubMed). This is why panthenol is common in products made for dry, tight or reactive skin, and in after-sun and after-exfoliation formulas.
Texture
Because it softens dry patches, panthenol makes skin feel smoother. Rough texture often comes from dehydration, so keeping the surface layer hydrated helps. See our guide to skin hydration for the wider picture.
Panthenol serum benefits
A serum is a light, water-based step. It suits humectants such as panthenol because the water-binding ingredient sits close to the skin and a moisturizer can follow on top.
What a panthenol serum offers:
- A lightweight layer of hydration that fits under makeup and sunscreen.
- A soothing step after cleansing, exfoliating or sun exposure.
- An easy way to add humectants without changing your moisturizer.
A dermatologist quoted by Alamo Heights Dermatology says dehydrated skin benefits from humectants such as hyaluronic acid, glycerin and panthenol. Layering a hydrating serum under a richer moisturizer often works best when concerns overlap (Alamo Heights Dermatology).
Apply serums to slightly damp skin. Water on the surface gives a humectant something to draw in. Our winter routine guide walks through applying humectants to damp skin.
Panthenol moisturizer benefits
A moisturizer is where panthenol's emollient side matters most. In a cream, it sits alongside oils, butters and lipids. The humectant draws water in, the emollient smooths, and the richer base slows water from leaving.
For dry skin, that combination is useful. The Alamo Heights dermatologist describes dry skin as a skin type that makes less oil, and says it needs emollients and occlusives, such as ceramides, squalane and shea butter, to restore the lipid barrier (source). A panthenol moisturizer adds humectant support on top of that. Ceramides are covered in our ceramides guide.

Panthenol vs hyaluronic acid
Both are humectants, and both help the skin hold water. They are not rivals. They have different strengths.
| Panthenol | Hyaluronic acid | |
|---|---|---|
| Type | Humectant and emollient | Humectant |
| Form on skin | Converts to vitamin B5 | Stays as a water-binding molecule |
| Best known for | Hydration, softening, soothing | Surface hydration, plumper feel |
| Common products | Serums, creams, masks, toners | Serums, essences, creams |
| Works with the other | Yes | Yes |
The comparison comes down to what you need. Hyaluronic acid is the straightforward choice for a hit of water. Panthenol adds softening and soothing on top of hydration, and has human data on hydration and barrier outcomes from the studies above. Dermatologists name both among the humectants that help dehydrated skin (Alamo Heights Dermatology).
If you already use hyaluronic acid and your skin still feels rough or tight, a panthenol product is a sensible addition. If you use hyaluronic acid on dry air days, seal it with an oil or cream. We explain how in layering hyaluronic acid with oil.
How to use panthenol in your routine
- Cleanse. Use a gentle cleanser that does not strip skin. See our double cleansing guide for oil and water cleansing.
- Tone or apply an essence. A hydrating toner can prepare skin. Leave it slightly damp.
- Apply a panthenol serum. A few drops over the face and neck.
- Moisturize. A cream with emollients and occlusives holds the water in.
- Use sunscreen in the morning. It is the final step of a morning routine. Our morning routine guide has the order.

Using panthenol with retinol or exfoliants
Panthenol is a gentle ingredient, and the soothing research above is the reason it is often placed in routines with stronger actives. A practical approach:
- Introduce one new active at a time.
- Use retinol or exfoliating acids on alternate evenings at first.
- Apply a hydrating and soothing step, such as a panthenol serum or moisturizer, on the same evening or on off nights.
- If your skin stings or turns red, stop the active and see a board-certified dermatologist.
There is no need to separate panthenol from most other skincare ingredients. The best proof is how your own skin responds, which is why a patch test is useful.
Side effects and safety
Panthenol is generally well tolerated. Allergic contact dermatitis is rare, and people who worry about irritation can patch test before using a product on the face or body (Medical News Today).
On regulation, Healthline reports that the FDA and the European Commission have approved panthenol for use in cosmetics. It also reports that the National Institutes of Health classifies it as possibly safe for general topical use and likely safe for topical use by children (Healthline).
How to patch test
- Apply a small amount of the product to the inner forearm or behind the ear.
- Leave it for 24 hours without washing the area.
- Check for redness, itching, swelling or bumps.
- If any appear, rinse the area and do not use the product.
Our patch test guide covers where to test and for how long. If you have eczema, a skin condition, or a known reaction to cosmetic ingredients, ask a dermatologist before adding a new product.
Who benefits most
- Dry skin: panthenol hydrates and softens.
- Dehydrated skin: oily skin can lack water too. Humectants help without heavy oils.
- Sensitive skin: the soothing action suits reactive skin, and patch testing keeps new products safe.
- Mature skin: well-hydrated skin looks smoother and fine lines look less pronounced.
- Skin in dry or cold weather: see our guide to winter hydration.
Our perspective
We formulate for sensitive, dry and reactive skin, and our approach is simple: short ingredient lists, plant-based formulas, and routines that hold up day after day.
Humectants matter in that approach. Hydration is the base of a healthy barrier, and we build routines around layers: water-binding steps first, then emollients and oils to seal. Panthenol fits the first two layers well, which is why it is worth knowing.
Our line is vegan and cruelty-free, and we hold Leaping Bunny certification. We believe skin does best with fewer, well-chosen products that work together. Read the ingredient list on any product you buy, and build your routine one step at a time.

FAQ
Is panthenol good for the skin?
Yes. Panthenol hydrates, softens and soothes, and studies link it to better hydration and lower transepidermal water loss (PubMed). It suits most skin types. As with any new product, patch test first.
What are the side effects of panthenol?
Side effects are uncommon. Allergic contact dermatitis is rare (Medical News Today). If you notice redness, itching or swelling, stop using the product and see a dermatologist.
Can I use panthenol with retinol?
Most people can use them in the same routine. Start retinol slowly, and use a hydrating step to support skin on the same night or on off nights. If irritation develops, pause the retinol and ask a dermatologist.
Is panthenol better than hyaluronic acid?
Neither is better across the board. Both are humectants that dermatologists recommend for dehydrated skin (Alamo Heights Dermatology). Panthenol also acts as an emollient, and the two can be layered.
Should I choose a panthenol serum or a moisturizer?
Choose a serum for lightweight hydration, and a moisturizer for softening and sealing. Many routines use both: serum first on damp skin, moisturizer after.
