Dexpanthenol (D-panthenol) converts into vitamin B5 (pantothenic acid) once absorbed - a vitamin essential to cell renewal and maintaining the skin barrier. But the same ingredient behaves very differently depending on the format it comes in. Ointment, cream, and serum differ in legal classification, permitted claims, and how you should actually use them.
The Core Split: Drug vs. Cosmetic
Ointment is a drug. A representative example is Bepanthen ointment, containing 50 mg of dexpanthenol per gram (5%) - a fixed concentration set by pharmaceutical standards. Per its product labeling, it's indicated for small, shallow wounds and minor burns, diaper rash, cracked nipples during breastfeeding, and supportive care for acute and chronic dermatitis. Follow the dosing on the label (1-2 times daily, applied thinly to clean skin). Do not use on infected skin conditions - anything oozing or weeping.
Note for U.S. readers: product names, availability, and regulatory classification for panthenol ointments vary by market. What stays constant is the principle below - an ointment indicated for wound and rash care is a different category of product from a daily-use cosmetic, whatever the label on your shelf says.
Cream and serum are cosmetics. Cosmetics legally cannot claim therapeutic effects. They can only make claims like "hydrates skin" or, where a market has a reviewed functional-cosmetic category, "supports barrier recovery." The simplest way to hold the distinction: an ointment is supportive care for a specific problem. A serum or cream is daily skin management.
How Each Format Behaves on Skin
Ointment. Heavy on oil-phase ingredients like paraffin and lanolin - occlusives, which block water from evaporating. It builds a strong protective film on the skin that shields against external stressors and reduces TEWL (transepidermal water loss), creating conditions for the skin to recover on its own. That's why it works on cracked skin.
Cream. An oil-and-water emulsion. Absorbs more readily, feels less tacky, and covers larger areas well. Practical for daytime and while you're active.
Serum / ampoule. A lightweight format built on water, glycerin, and humectants. Dexpanthenol concentration varies by product, but typically sits in the 1-5% range. Easy to layer, which makes it a good first hydration step right after cleansing.
Which Format for Which Situation
Reach for an ointment for small cuts, abrasions, and minor burns; infant diaper rash; cracked nipples while breastfeeding (wipe clean before feeding); or severely cracked hands and feet.
Reach for a cream to hydrate and calm large areas of face or body, on sweaty or hair-bearing areas like the groin or underarms, or during the day when shine is a concern.
Reach for a serum to start barrier care with hydration as the first post-cleanse step, during seasonal transitions or heated indoor air that leaves skin tight and red, or after exfoliating care like retinol or AHA when skin is reactive.
Important: if there's weeping or pus, that can indicate infection - see a doctor before self-treating.
How to Use Each One
Ointment: 1-2 times daily, applied thinly to clean skin. Localized areas only (cracks, rash). If symptoms don't improve or get worse, seek care immediately.
Cream: cleanse, then serum, then cream, then sunscreen. Dispense into your hand and apply in several thin passes to reduce patchiness.
Serum: 1-2 pumps right after cleansing, let it absorb, then seal with cream. On dry days, two layers works well.

Precautions and Side Effects
Watch for allergic contact dermatitis (delayed-type hypersensitivity) - if you develop itching, redness, or small blisters, stop use immediately. Do not apply to eyes or mucous membranes. For deep wounds or suspected infection, see a doctor rather than self-treating. An ointment is a drug, so follow the label instructions.
Quick Comparison
Ointment is classified as a drug, with a high-oil base that feels slick and noticeably shiny. Occlusivity is very high, and it's best for very dry, cracked skin, protecting small wounds, and supportive care for diaper rash.
Cream is classified as a drug or cosmetic depending on the formula, with an oil-and-water blend that's easy to apply and remove. Occlusivity is moderate, and it's best for daily hydration and calming over large areas, sweaty or hair-bearing areas, and daytime use.
Serum / ampoule is classified as a cosmetic, with a water-phase and humectant-led base that's light and easy to layer. Occlusivity is low, and it's best as the first hydration layer in daily barrier care and for layering with other actives.
Putting it together: whole-face hydration and calming calls for serum plus cream. Localized cracking or rash calls for ointment as spot care. If needed, layering serum, then cream, then ointment (on the specific areas only) is the most effective sequence.
The 75% Serum: What "Ultra-High Concentration" Means Here
Since serums typically sit in the 1-5% range, it's worth being specific about what sits above it. SkinStandard's 75% Dexpanthenol Add-on Serum is the product referenced above, and here is the evidence behind the number.
Concentration. 75% (750,000 ppm) - roughly 15x the ~5% in a pharmacy panthenol ointment, using only the active D-form rather than a diluted D/L mix. Dexpanthenol is the formula's core active, not a supporting ingredient.
Ointment-style occlusives deliberately left out. The occlusives that make an ointment effective on cracked skin - paraffin, white petrolatum, lanolin - are also what make it unsuitable for whole-face daily use, per the FAQ below. This formula excludes them entirely. Nano-emulsified squalane handles absorption in both the oil and water phases so a high concentration doesn't sit on the surface, and citric acid holds pH at 5.5±0.5. Total formula: 7 ingredients, with every raw material's amount disclosed to 0.001%.
Clinical results (independent clinical research institute, 22 adult women, individual results vary): a single application raised hydration by 122.3% at 24 hours and cut TEWL by 30.1% by the next morning. After 14 days of continued use, deep hydration rose 8.8% and barrier recovery rose 23.1%. On freshly irritated skin, the formula showed a 78.4% immediate soothing-recovery rate versus 18.3% natural recovery on untreated skin, with no adverse reactions reported. A separate primary irritation test on sensitive skin scored 0.00 (the lowest possible), with no added fragrance, dye, or alcohol.
Format logic. It's built as an add-on - one pump mixed into your existing moisturizer, serum, or foundation, with the amount adjusted to your skin. That's what makes a concentration this high practical for daily use rather than occasional spot treatment, and it fits the serum-layer role described above.

Frequently Asked Questions
Can I use panthenol ointment in the morning?
Yes. The "vitamins shouldn't be exposed to sunlight" advice applies mainly to vitamin C and vitamin A forms. Dexpanthenol (vitamin B5) is stable in sunlight. That said, if you have a recurring skin issue, see a dermatologist.
Can I use ointment as my everyday moisturizer?
Not recommended. Panthenol ointment is a drug for supportive care - localized treatment for wounds, rashes, and inflammation. For everyday hydration over larger areas, a cosmetic serum or cream is the better fit.
Is it safe during early pregnancy?
Generally yes. Dexpanthenol is a precursor to vitamin B5, which is present in food, and is regarded as benign. Individual responses vary, so if a skin issue persists during pregnancy, consult a physician.
Can I use it after a tattoo?
Yes - panthenol ointment is often recommended after tattooing for its low irritation and protective function. Avoid ointments formulated for different purposes (those containing antibiotics or steroids), and use verified tattoo aftercare or known-safe products.
Can I apply ointment over my whole face?
Not recommended. The high oil content can clog pores and look shiny, and for oily or breakout-prone skin, it can trigger breakouts. Use a serum or an easily absorbed cream for the full face.
How much dexpanthenol is actually in a cosmetic product?
It varies. Most sit in the 1-5% range, and a "10" in the product name doesn't necessarily mean 10% concentration. Always check the ingredient list and whether the brand publishes the actual figure. In the U.S., cosmetic labels aren't required to disclose percentages at all - only INCI order - so a stated number is a voluntary disclosure.
