Lard can be a decent moisturizer for your skin, though it’s far from a miracle ingredient. Its fatty acid profile overlaps with some of the fats naturally found in human skin, which means it absorbs reasonably well and creates a protective barrier against moisture loss. But it also has real limitations, and the online enthusiasm around animal fats for skincare often outpaces the actual evidence.
Why Lard Works as a Moisturizer
Lard’s usefulness on skin comes down to its fatty acid makeup. Pig lard has a saturation ratio of roughly 42% saturated fats, 46% monounsaturated fats, and 6% polyunsaturated fats. The key players are oleic acid, palmitic acid, and stearic acid, all of which are also found in the outer layer of human skin (the stratum corneum). Palmitic acid and stearic acid are the two most common saturated fatty acids in animal fats, and both have a long history of use in salves and ointments for irritated or inflamed skin.
Your skin’s protective barrier is built from cholesterol, free fatty acids, and ceramides. When that barrier is compromised, whether from dry air, harsh cleansers, or skin conditions, applying a fat rich in compatible fatty acids can help fill the gaps. Lard’s oleic acid content is particularly relevant here: oleic acid is a well-known skin-penetration enhancer, meaning it doesn’t just sit on the surface. It sinks in and softens the upper layers of skin. Palmitic acid, meanwhile, acts more as an occlusive, forming a layer that slows water evaporation from the skin’s surface.
How It Compares to Other Animal Fats
You’ll often see lard discussed alongside beef tallow in natural skincare circles, and the two are genuinely similar. Both are rich in oleic, palmitic, and stearic acids. Tallow tends to be slightly harder and waxier at room temperature due to a higher proportion of saturated fats, while lard is softer and spreads more easily. In practical terms, lard feels less greasy on the skin than you might expect and absorbs faster than something like coconut oil.
That said, neither lard nor tallow contains meaningful amounts of linoleic acid, a polyunsaturated fatty acid that plays a critical role in skin barrier function. People with acne-prone skin often have lower linoleic acid levels in their sebum. Since lard is relatively low in polyunsaturated fats, it may not address that particular imbalance the way a plant oil high in linoleic acid (like sunflower seed oil or hemp seed oil) would.
The Vitamin D Claim
One claim that circulates frequently is that lard is rich in vitamin D and can deliver it through your skin. The reality is more complicated. Pigs raised outdoors with sun exposure do accumulate vitamin D in their fat tissue, with subcutaneous fat containing around 46 nanograms per gram of vitamin D3 in sun-exposed animals. That’s a modest amount, and there’s no published research showing that applying lard topically delivers vitamin D into the body in any meaningful way. Your skin synthesizes its own vitamin D from sunlight through a specific biochemical process that doesn’t work in reverse by rubbing a vitamin D-containing fat onto it.
Most commercially available lard comes from conventionally raised pigs with limited sun exposure, which means the vitamin D content is even lower. This claim, while not entirely fabricated, is significantly overstated as a reason to use lard on your skin.
Where Lard Falls Short
The biggest gap in the lard-for-skin conversation is the lack of clinical evidence. No published dermatological studies have tested lard as a standalone treatment for eczema, dermatitis, or other inflammatory skin conditions. The existing research on animal fats and skin compatibility is almost entirely compositional, meaning scientists have compared the fatty acid profiles of tallow and lard to skin lipids on paper, but haven’t run controlled trials on human volunteers to measure outcomes like reduced redness, improved hydration, or barrier repair.
Lard also contains no antioxidants, no anti-inflammatory compounds, and no vitamins in concentrations that matter topically. Compare that to something like rosehip oil, which contains both linoleic acid and vitamin A derivatives, or even shea butter, which has naturally occurring anti-inflammatory compounds. Lard is essentially a blank canvas of fat. It moisturizes, but it doesn’t do much else.
Shelf Life and Rancidity Concerns
Because lard contains some polyunsaturated fats, it oxidizes over time. Fresh rendered lard has a very low peroxide value (around 2.6 milliequivalents per kilogram), indicating minimal oxidation. But exposure to heat, light, and air accelerates breakdown significantly. Lard that’s been repeatedly heated, for instance, can reach peroxide values five times higher.
Rancid fat on your skin isn’t just unpleasant to smell. Oxidized lipids can generate free radicals that damage skin cells, essentially doing the opposite of what you’re trying to achieve. If you’re going to use lard on your skin, store it in the refrigerator in an airtight container and discard it if it develops an off smell or yellowish discoloration. Properly stored, rendered lard typically stays fresh for several months in the fridge or up to a year in the freezer.
How to Use Lard on Skin
If you want to try lard as a moisturizer, start with high-quality rendered lard from pasture-raised pigs. Leaf lard, which comes from around the kidneys, is the cleanest and least “porky” smelling option. You can apply a small amount directly to damp skin after a shower, which helps it spread more easily and locks in the water already on your skin’s surface.
Lard also has a long history as a base ingredient in soap. In cold-process soapmaking, lard produces a hard, long-lasting bar with a creamy lather. Some soapmakers leave a small percentage of unsaponified fat in the final product (called superfatting), which adds extra moisturizing properties to the bar. If applying straight animal fat feels unappealing, a lard-based soap is a more approachable way to get some of its skin benefits.
For people with sensitive or reactive skin, patch test on a small area of your inner forearm before applying it to your face or any irritated areas. Lard is generally well tolerated, but individual reactions vary, and oleic acid can occasionally worsen barrier function in skin that’s already significantly compromised.
