Petrolatum: When Your Skin Needs Extra Protection
If your skin feels very dry, tight, rough, or uncomfortable, especially around your nose, mouth, hands, or lips, petrolatum can be a helpful ingredient to look for.
As a skincare-store employee, I would explain petrolatum in a very simple way: it is an ingredient that helps keep moisture from leaving your skin.
It does not add water to your skin by itself. Instead, it forms a thin protective layer on top of the skin, like putting a lid on a pot. The lid does not create steam, but it helps keep the steam from escaping. Petrolatum works in a similar way by helping keep existing moisture from evaporating too quickly.
What Is Petrolatum?
Petrolatum is also called petroleum jelly. You may know it from products such as Vaseline.
On an ingredient list, you will usually see the word “petrolatum.” It is often found in thick creams, ointments, lip balms, diaper creams, hand balms, and products made for very dry skin.
Petrolatum is an occlusive ingredient. That means it sits on the surface of the skin and helps create a protective layer.
It is not glamorous, and it is not usually the ingredient that makes a product feel light or luxurious. But when skin is dry and stressed, it can be very useful.
Petroleum jelly is a highly occlusive ointment that forms a protective layer, helping seal in hydration and reduce moisture loss from the skin.
When I Would Recommend It
I would suggest petrolatum when your skin feels more than just a little dry.
It can be especially helpful when cold winter air, dry indoor heat, air conditioning, frequent handwashing, or strong skincare products make your skin feel tight and uncomfortable.
I would also consider it when your lips are cracked, your hands feel dry after washing them, your elbows or heels feel rough, or the skin around your nose becomes dry after a cold or allergies.
At night, it can be useful on small dry areas of the face. For example, a tiny amount over moisturizer around the nose, mouth, or cheeks can help keep those areas from drying out overnight.
Petrolatum is often most useful during cold, dry weather or when the skin barrier is dehydrated and needs help holding onto moisture.
How to Use It
The easiest way to use petrolatum is to apply it after a moisturizer.
First, use a hydrating lotion, cream, or serum. Then apply a very small amount of petrolatum over the driest areas.
This order makes sense because your moisturizer gives the skin hydration, while petrolatum helps keep that hydration from escaping.
For lips, hands, elbows, heels, or dry patches around the nose, you can apply a small amount directly to clean skin.
At night, some people apply a thin layer over their moisturizer as the final step. This is sometimes called “slugging.” It can be helpful for very dry skin, especially during winter.
You do not need a thick layer. A little goes a long way.
When petrolatum is layered over a moisturizer, it can help lock in hydration and protect the skin from further water loss.
Who May Like It Most
Petrolatum may be a good choice if you have dry skin, sensitive-feeling skin, mature skin, or skin that becomes dry during winter.
It can also be helpful for people who use retinol, exfoliating acids, or acne treatments and notice dry areas around the nose, mouth, or cheeks.
If your hands are dry from frequent washing, hand sanitizer, cleaning, gardening, or cold weather, applying a petrolatum-based hand balm before bed can feel very comforting.
If your lips become dry easily, a simple petrolatum lip balm can help protect them from wind and dry air.
Petrolatum is commonly used in products made for dry, irritated, or eczema-prone skin because it can help protect the surface of the skin and lock in moisture.
When to Use Less
Petrolatum can feel too heavy for some people, especially during hot or humid weather.
If you have oily or acne-prone skin, you may prefer to use it only on very dry spots instead of applying it over your entire face.
I would not put a thick layer of petrolatum over skin that feels very irritated after using a strong product without first stopping the product that is causing the irritation. If you have a painful rash, swelling, signs of infection, or skin that does not improve, it is best to speak with a dermatologist.
The goal is not to cover your face in a heavy layer every night. The goal is to use a small amount where your skin needs extra protection.
A Simple Shopping Tip
When you see petrolatum on a product label, think of it as a moisture-locking ingredient.
A product with petrolatum may be a good choice when you need more protection than a lightweight lotion can provide.
For daytime, I usually prefer a regular moisturizer and sunscreen. For nighttime, dry hands, lips, heels, elbows, or dry patches on the face, petrolatum can be a very practical choice.
You do not need an expensive product. A simple fragrance-free petrolatum ointment can be enough for many dry areas.
Final Thoughts
Petrolatum is not a trendy ingredient, but it is one of the easiest to understand.
It helps keep moisture from escaping. It is most helpful when skin feels very dry, rough, tight, or uncomfortable.
Use it after moisturizer, apply only a small amount, and focus on the areas that need extra care.
When your skin needs a simple protective layer, petrolatum can be a useful and affordable option.
