Aquaphor is not petroleum jelly, but petroleum jelly is its main ingredient. Aquaphor Healing Ointment contains 41% petrolatum (the pharmaceutical name for petroleum jelly), blended with several other ingredients that give it different properties. Vaseline, by comparison, is 100% petroleum jelly. The two products look similar and serve overlapping purposes, but they’re formulated differently and work on skin in distinct ways.
What’s Actually in Aquaphor
Petrolatum makes up 41% of Aquaphor’s formula and is listed as its only active ingredient. The remaining 59% is a blend of six inactive ingredients: mineral oil, ceresin (a mineral wax), lanolin alcohol (derived from sheep’s wool), glycerin, panthenol (a form of vitamin B5), and bisabolol (derived from chamomile). Each of these plays a specific role in how the product feels and performs on skin.
Glycerin is the most functionally important addition. It’s a humectant, meaning it pulls water into the skin rather than just sitting on top. Petroleum jelly alone only seals moisture in. Glycerin actively draws moisture toward the skin’s surface, which makes a meaningful difference for very dry or cracked skin. Panthenol adds softening and smoothing effects, while lanolin alcohol is a natural emollient that reinforces the moisture barrier. Bisabolol, from chamomile, has mild soothing properties.
How Both Products Work on Skin
Pure petroleum jelly and Aquaphor share one core function: they’re both occlusive moisturizers. That means they coat the skin’s surface with a water-repellent layer that prevents moisture from evaporating. This traps water in the outermost layer of skin, temporarily improving hydration and reducing dryness. For people with eczema or other conditions where the skin barrier is compromised, this sealing effect can also help calm inflammation by keeping the skin hydrated.
Where they diverge is in the second layer of benefit. Aquaphor’s glycerin component means it works as both an occlusive and a humectant. It doesn’t just lock in existing moisture; it helps hydrate skin that has already lost water. This dual mechanism is why dermatologists often describe Aquaphor as the better moisturizer of the two, particularly for extremely dry or damaged skin.
The texture difference follows from the formulation. Vaseline feels thicker and greasier because it’s pure petrolatum. Aquaphor has a slightly softer, more spreadable consistency thanks to the mineral oil, ceresin wax, and other additives.
When Each One Makes More Sense
For basic skin protection where you just need a barrier, either product works. Dermatology departments at major medical centers list Aquaphor and Vaseline interchangeably for post-surgical wound care, recommending either one be applied to sutured wounds or healing skin under a bandage. In clinical settings, Aquaphor has shown some advantages: one study comparing it against another topical emulsion after laser skin resurfacing found that Aquaphor produced significantly less redness and crusting at days two and seven, faster skin regrowth by day four, and less stinging, itching, and tightness overall.
For everyday dry skin or cracked lips, Aquaphor’s humectant ingredients give it an edge. If you’re dealing with eczema or seasonal dryness, the glycerin in Aquaphor provides hydration that pure petroleum jelly can’t match on its own. On the other hand, Vaseline’s simplicity is an advantage for people with sensitive skin or ingredient allergies, since there are fewer components that could cause a reaction.
Potential Drawbacks of Aquaphor
The lanolin alcohol in Aquaphor is a known allergen for a small percentage of people. Patch testing studies place the prevalence of lanolin allergy between roughly 1% and 6% of patients tested, depending on the specific testing method used. If you notice redness, itching, or irritation after applying Aquaphor, lanolin sensitivity is the most likely culprit. Vaseline, being pure petrolatum with no additives, carries virtually no allergy risk.
For acne-prone skin, Aquaphor requires some caution. The manufacturer states it’s noncomedogenic (won’t clog pores), and for people with dry to normal skin, that generally holds true. But if you have naturally oily skin, applying Aquaphor to your face can trap too much moisture and prevent pores from breathing. Applying it over unwashed skin can also seal in dirt and oil. Both scenarios can trigger breakouts. If you’re acne-prone, using Aquaphor on the face is best avoided or limited to small, dry patches rather than broad application.
The Bottom Line on Classification
Aquaphor is an ointment that contains petroleum jelly. It is not petroleum jelly itself. The distinction matters because Aquaphor’s additional ingredients change how it interacts with skin, making it a more active moisturizer rather than a simple barrier. If a product recommendation calls for “petroleum jelly” specifically, Vaseline or any store-brand 100% petrolatum product is the accurate match. If it calls for “Aquaphor or similar healing ointment,” you’re looking at a different category of product, one that petroleum jelly alone won’t fully replicate.
