Aquaphor Healing Ointment contains 41% petrolatum as its active ingredient, combined with a short list of inactive ingredients: mineral oil, ceresin (a mineral wax), lanolin alcohol, panthenol, glycerin, and bisabolol. The formula is fragrance-free and preservative-free, with each ingredient serving a specific role in skin protection and moisture retention.
The Active Ingredient: Petrolatum
Petrolatum makes up 41% of Aquaphor’s formula and does the primary work. It sits on top of the skin and forms a physical barrier that prevents water from evaporating. This is what makes it an “occlusive” moisturizer: it doesn’t add moisture so much as it locks in the moisture your skin already has. Petrolatum has decades of use in wound care and skin protection, and it remains one of the most effective barrier ingredients available over the counter.
For comparison, Vaseline is 100% petrolatum. Aquaphor uses that same base at a lower concentration, leaving room for additional ingredients that actively hydrate and soothe the skin rather than just sealing it.
What the Other Ingredients Do
The remaining 59% of Aquaphor’s formula is a mix of emollients, humectants, and plant-derived soothers. Each one plays a distinct role:
- Mineral oil softens the texture of the ointment and helps it spread easily. It also adds a layer of emollient protection.
- Ceresin is a mineral wax derived from shale rock. It gives Aquaphor its thick, ointment-like consistency and helps stabilize the formula.
- Lanolin alcohol is a natural fat derived from sheep’s wool. It acts as an emollient and helps the ointment blend with the skin’s own oils, improving absorption.
- Glycerin is a humectant, meaning it pulls water toward itself. While petrolatum stops moisture from leaving, glycerin actively draws hydration into the upper layers of skin. This combination of locking in and pulling in moisture is what makes Aquaphor more hydrating than plain petroleum jelly.
- Panthenol is a form of vitamin B5. It holds moisture in the skin while softening and smoothing the surface. It also supports the skin’s natural repair process.
- Bisabolol is extracted from chamomile. It has mild anti-inflammatory and soothing properties, which help calm irritated or damaged skin.
How It Works on Skin
Aquaphor is classified as a semi-occlusive barrier. Unlike pure petrolatum, which creates a nearly airtight seal, Aquaphor’s blend of ingredients allows some air and moisture exchange while still preventing significant water loss. This matters for healing skin, where some breathability is helpful.
The formula works in layers. Glycerin and panthenol hydrate the skin directly. Lanolin alcohol helps these ingredients absorb rather than just sitting on the surface. Then petrolatum, mineral oil, and ceresin form a protective coat over everything, keeping that hydration in place. The result is both immediate softening and longer-term moisture retention.
The Lanolin Sensitivity Question
Lanolin alcohol is the one ingredient in Aquaphor that causes problems for a small number of people. Among the general population, fewer than 0.5% have a true contact allergy to lanolin. That number rises to between 1.7% and 3.3% in people who already have dermatitis and are undergoing patch testing for allergies.
The free alcohols in lanolin are considered the main sensitizers. People with compromised or broken skin are at higher risk, which includes those with eczema, venous leg ulcers, or chronic wounds. Children and older adults tend to have slightly higher rates of lanolin sensitivity, largely because both groups have higher rates of conditions that disrupt the skin barrier. If Aquaphor causes redness, itching, or worsening irritation, lanolin allergy is the most likely culprit.
What It Doesn’t Contain
Aquaphor’s formula is notable for what it leaves out. There are no fragrances, no dyes, and no preservatives. This minimal approach is one reason dermatologists frequently recommend it for sensitive or post-procedure skin. The ingredient list is short enough that if you do react to it, the cause is relatively easy to identify (usually the lanolin).
Common Uses and One Caveat
Dermatologists commonly recommend Aquaphor for dry, cracked skin, chapped lips, minor cuts and scrapes, and post-procedure wound care after skin surgeries or laser treatments. Its combination of occlusive and humectant properties makes it more versatile than plain petroleum jelly for these purposes.
One thing worth knowing: a study published in the Journal of Drugs in Dermatology comparing Aquaphor to plain white petrolatum on surgical wounds found that Aquaphor resulted in significantly more redness and swelling than white petrolatum alone. The study looked at patients recovering from Mohs surgery on the head and neck, and 52% of those using Aquaphor showed redness at the wound site, with 33% showing both redness and swelling. This may be related to the lanolin content or other additives. For fresh surgical wounds specifically, plain petrolatum may sometimes be the simpler choice.
For everyday dry skin, minor irritation, and general skin protection, Aquaphor’s fuller ingredient list works in its favor. The humectants and soothing agents give it a meaningful advantage over petroleum jelly alone for restoring and maintaining skin hydration.
