Petroleum jelly is generally considered safe to use during pregnancy for common skin issues like dryness, chapped lips, and minor irritation. It is a highly refined product that does not absorb deeply into the skin, and no credible evidence links topical use to harm for you or your baby. However, there are a few important distinctions between plain petroleum jelly and products that contain other ingredients, which we cover below.
What Is Petroleum Jelly Made Of?
Petroleum jelly, often sold under brand names like Vaseline, is a semi-solid mixture of hydrocarbons. It comes from crude oil, but it goes through a rigorous purification process before it reaches store shelves. The final product is a bland, stable ointment that has been used for over a century in skincare and wound care.
In the United States, the Food and Drug Administration regulates petroleum jelly as an over-the-counter skin protectant. The manufacturing process removes impurities, and the finished product is tested to meet specific safety standards. This is not the same as raw petroleum or industrial grease, which are not safe for skin contact.
The key point is that cosmetic-grade and pharmaceutical-grade petroleum jelly are refined to a very high standard. When you buy a product labeled for skin use from a reputable brand, it is a different material entirely from unrefined petroleum products.
Can Petroleum Jelly Be Absorbed Through The Skin?
Petroleum jelly works by sitting on the surface of the skin. Its molecules are too large to penetrate the outer skin layer in any meaningful amount. Instead, it forms a physical barrier that traps moisture in and keeps irritants out.
This matters for pregnancy safety. Because the jelly does not enter your bloodstream in significant quantities, it does not have a route to reach the developing baby. Transdermal absorption is the main concern with any topical product during pregnancy, and petroleum jelly scores very low on that measure.
Some research has looked at whether hydrocarbons from petroleum jelly can be found in human tissues. These studies generally involve people who used the product heavily for years, not routine pregnancy use. The amounts detected are small, and no study has linked this to pregnancy complications or birth defects.
Is It Safe To Use On The Belly And Stretch Marks?
Many pregnant women use petroleum jelly on the abdomen to prevent or reduce stretch marks. The jelly itself is safe for this purpose, but it is important to be realistic about what it can do.
Stretch marks form when the skin stretches faster than it can produce collagen. Moisturizers and occlusive agents like petroleum jelly can improve skin hydration and may reduce itching. They do not prevent stretch marks entirely, and genetics play a larger role than any topical product.
If you choose to apply petroleum jelly to your belly, there is no safety concern. It will not harm the baby. Just know that it is doing the job of a moisturizer, not a medical treatment. If you develop severe itching or a rash on the belly, talk to your obstetrician rather than treating it yourself with heavier products.
Are There Any Risks With Petroleum Jelly During Pregnancy?
The main risks are not from the jelly itself but from how it is used and what is mixed into it.
First, petroleum jelly is not sterile. It is not meant to be applied to open wounds, surgical incisions, or broken skin unless a healthcare provider specifically recommends it. During pregnancy, if you have a tear, a healing episiotomy, or a cesarean incision, follow your doctor’s instructions for wound care instead of applying petroleum jelly on your own.
Second, some products labeled as petroleum jelly contain added fragrances, dyes, or botanical extracts. These additives are more likely to cause skin irritation or allergic reactions than the plain jelly. During pregnancy, skin can become more sensitive, so plain, unflavored petroleum jelly is the safer choice.
Third, there is a rare risk called lipoid pneumonia if petroleum jelly is inhaled into the lungs. This happens when people use it inside the nose and then inhale deeply, or when infants are given petroleum jelly products near their airways. If you use petroleum jelly for nasal dryness during pregnancy, apply a thin layer just inside the nostrils with a cotton swab and do not inhale forcefully.
Does Petroleum Jelly Contain Harmful Chemicals?
This is a common concern because petroleum jelly comes from crude oil. The purification process is designed to remove polycyclic aromatic hydrocarbons (PAHs), which are the compounds that raise cancer concerns in unrefined petroleum products.
The United States Pharmacopeia (USP) grade petroleum jelly meets strict standards for purity. Products that carry the USP label have been tested and meet those standards. The FDA also sets limits for impurities in cosmetic petroleum jelly.
Some independent testing has found trace amounts of PAHs in certain petroleum jelly products. The levels are very low and are not known to pose a health risk from normal skin application. If you want to minimize even trace exposures, choose a product that is labeled USP grade and avoid products with added ingredients.
It is also worth noting that the European Union has stricter regulations on PAH content in consumer products than the United States. Some brands sell the same formula globally, so a product that meets EU standards also meets US standards. Reading labels and choosing reputable brands is the most practical approach.
Are There Better Alternatives For Pregnancy Skin Care?
Petroleum jelly is not the only option, and some people prefer alternatives for personal reasons. The alternatives below are also generally considered safe during pregnancy, but none of them are clearly better than petroleum jelly for basic skin protection.
- Shea butter — a plant-based fat that moisturizes and is generally safe during pregnancy. It absorbs more than petroleum jelly but does not form as strong a barrier.
- Cocoa butter — commonly used for stretch marks, though evidence for prevention is limited. It is safe but not more effective than simpler moisturizers.
- Beeswax-based balms — provide a barrier similar to petroleum jelly and are safe for topical use.
- Oatmeal-based creams — helpful for itchy, irritated skin and safe during pregnancy.
None of these alternatives have been proven superior to petroleum jelly in clinical trials for pregnancy-related skin issues. The choice comes down to personal preference, skin sensitivity, and cost.
If you are looking for a product specifically to prevent stretch marks, no topical product has strong evidence of effectiveness. Keeping skin hydrated may reduce discomfort, but the development of stretch marks is largely determined by hormones and genetics.
What About Using Petroleum Jelly On A Newborn?
This is a separate question from pregnancy safety, but it comes up often. Petroleum jelly is commonly used on infants for diaper rash and dry skin. It is generally considered safe for babies, but there are important precautions.
Do not use petroleum jelly on a newborn’s face or near the mouth and nose. The risk of inhalation and lipoid pneumonia is real in infants. For diaper rash, a thin layer is fine, but keep it away from the genital opening in baby girls.
For pregnancy purposes, the main point is that petroleum jelly you use during pregnancy will not affect the baby before birth. After birth, the same product can be used on the baby with the precautions above.
Frequently Asked Questions
Can I use petroleum jelly on my stomach while pregnant?
Yes, it is safe to apply petroleum jelly to your stomach during pregnancy. It will not be absorbed into your bloodstream and does not reach the baby.
Is Vaseline safe to use during pregnancy?
Yes, plain Vaseline is safe for topical use during pregnancy. Choose the original, unflavored formula without added fragrances or medicated ingredients.
Can petroleum jelly cause birth defects?
No evidence links topical petroleum jelly use to birth defects. It does not penetrate the skin in significant amounts, so it does not enter your bloodstream in quantities that could affect fetal development.
Is it safe to use petroleum jelly for hemorrhoids during pregnancy?
Petroleum jelly can be applied externally for comfort, but it does not treat hemorrhoids. For internal hemorrhoids, talk to your doctor about pregnancy-safe options like stool softeners or medicated wipes.
