Understanding the Core Ingredient: Petrolatum
Both Aquaphor and Vaseline belong to a class of topical products known as occlusive moisturizers, which means they form a thick, protective layer on the skin's surface. This layer's primary function is to prevent transepidermal water loss (TEWL), effectively sealing in existing moisture to keep the skin hydrated. This ability to create a barrier is what makes both products so effective for treating and protecting dry or irritated skin.
The active ingredient responsible for this powerful occlusive effect is petrolatum, also known as petroleum jelly. Vaseline's formula is famously simple, consisting of 100% pure white petrolatum, a formulation that has made it a household name for over a century. In contrast, Aquaphor Healing Ointment contains a lower percentage of petrolatum, around 41%, and supplements this with a range of additional moisturizing and healing agents.
The Crucial Differences: Additives and Their Impact
Aquaphor's multi-ingredient formula is the key differentiator. Beyond its petrolatum base, it contains several inactive but beneficial ingredients that change its properties and functionality compared to pure Vaseline. These additives include:
- Glycerin: A humectant, meaning it actively draws moisture into the skin, providing a deeper level of hydration.
- Lanolin Alcohol: An emollient derived from sheep's wool that helps soften and smooth the skin.
- Panthenol: A form of Vitamin B5 known for its skin-soothing and healing properties.
- Bisabolol: An anti-inflammatory agent derived from chamomile that helps soothe irritated skin.
- Mineral Oil and Ceresin: These add to the ointment's texture and help create the protective barrier.
Because of these additional components, Aquaphor is often considered a more comprehensive skin treatment, especially for conditions where deep hydration is needed. Its complex formula provides both occlusive and humectant benefits, making it particularly effective for very dry, cracked skin and eczema. Vaseline, with its singular ingredient, is purely an occlusive sealant, relying on moisture already present in the skin rather than actively drawing more in.
Comparison Table: Aquaphor vs. Vaseline
To help illustrate the key distinctions, here is a breakdown of how Aquaphor and Vaseline compare across several categories:
| Feature | Aquaphor Healing Ointment | Vaseline Original Petroleum Jelly |
|---|---|---|
| Active Ingredient | 41% Petrolatum | 100% White Petrolatum |
| Additional Ingredients | Lanolin Alcohol, Glycerin, Panthenol, Bisabolol, Mineral Oil, Ceresin | None |
| Primary Function | Provides both hydration (humectant) and moisture retention (occlusive) | Creates a strong occlusive barrier to prevent moisture loss |
| Best For | Eczema, severely dry/cracked skin, chapped lips, tattoo aftercare | Simple wound protection, preventing chafing, slugging on non-acne-prone skin |
| Texture/Feel | Lighter, spreads more easily, and less greasy | Thicker, greasier, and heavier |
| Risk of Allergic Reaction | Higher due to ingredients like lanolin | Very low, as it contains only one purified ingredient |
| Cost | Tends to be more expensive due to complex formula | Generally more affordable |
| Tattoo Aftercare | Widely recommended due to breathable properties | Generally not recommended as it may hinder healing |
Deciding Which One to Use: A Guide to Best Practices
Making the right choice between Aquaphor and Vaseline often comes down to your specific skin needs and sensitivities. Dermatologists agree that both are safe and effective, but their subtle differences make one more suitable for certain situations.
For Dry and Cracked Skin
If your skin is extremely dry or cracked, Aquaphor's blend of humectants and emollients provides a more active moisturizing effect than Vaseline alone. The glycerin and lanolin attract and lock in moisture more effectively, making it a powerful choice for conditions like eczema and severely chapped lips.
For Wound Healing
For treating minor cuts, scrapes, and post-surgical wounds, Vaseline is often preferred by healthcare providers. Its simple, pure formula minimizes the risk of irritation or allergic reaction, which can be a concern with Aquaphor's lanolin content. A study on post-surgical wounds even found that Vaseline caused less redness and swelling compared to Aquaphor. For this reason, those with sensitive or compromised skin may benefit from Vaseline's straightforward, gentle protection.
For Face and 'Slugging'
The skincare practice of 'slugging,' where a thick occlusive is applied to the face overnight, can be done with either product. However, those with oily or acne-prone skin may find Aquaphor more suitable. Its lighter, less greasy texture feels less heavy on the face and can be more breathable. While both are considered non-comedogenic, they can still trap dirt and oil if the skin is not properly cleansed beforehand, potentially causing breakouts.
For Allergies and Sensitivity
Approximately 5% of people have an allergy to lanolin. Since Aquaphor contains lanolin, it poses a small risk of contact dermatitis for those individuals. Vaseline, containing only one highly purified ingredient, is a safer option for those with sensitive skin or known lanolin allergies.
Other Uses
Both products are versatile and have numerous other applications, such as preventing chafing during exercise or softening cuticles. Some users prefer the feel of Aquaphor for daily cosmetic purposes, like as a lip balm or makeup primer, while Vaseline is often a more budget-friendly option for widespread application. Ultimately, having both on hand can be beneficial, as they serve different but equally valuable purposes in a skincare regimen.

Conclusion
In summary, the notion that is Aquaphor basically Vaseline is a common misconception. While both use a petrolatum base to create an occlusive barrier for the skin, their added ingredients create a fundamental difference in how they function. Vaseline's 100% petrolatum formula is a pure occlusive, ideal for simple barrier protection and wound care due to its minimal risk of irritation. Aquaphor, with its blend of humectants and emollients, offers a more comprehensive healing and hydrating treatment, making it better for severely dry skin and eczema. Your choice depends on your specific skin needs, sensitivity, and texture preference. When in doubt, a patch test is always recommended, especially if you have allergies or very sensitive skin.
