Lard

INCI: Adeps Suillus

Lard is a traditional emollient that softens skin but may clog pores for some people.

beautyskincareemollient

In plain English

Lard is pig fat that has been rendered and purified for use in skincare. It works by coating the skin with a protective layer that locks in moisture and prevents water loss. Because it is rich in fatty acids similar to those naturally found in skin, it can feel nourishing and softening. However, it is heavy and may block pores, so it is not ideal for oily or acne-prone skin.

Quick decision guide

Useful, but context matters

Lard can be useful, but watch for possible clogging concerns.

Plain-English read

Treat this as a practical screening step before you compare products that contain this ingredient.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Lard.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.

Score terms in plain English

Irritation risk

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

moderate

May be fine for many users but deserves caution if you are breakout-prone.

Evidence level

moderate

There is useful support, but formula details and claim strength still matter.

What it is

Lard is a rendered fat from pigs, composed primarily of triglycerides (oleic, palmitic, and stearic acids). In cosmetics, it is refined to remove impurities and odor, and used as an emollient and occlusive ingredient.

How it works

Lard forms a thin, greasy film on the skin's surface that reduces transepidermal water loss (water evaporating from the skin). Its fatty acids help soften and smooth the skin by filling in gaps between skin cells.

Pros

Deeply moisturizing

Lard is an effective occlusive that prevents water loss, making it excellent for very dry or chapped skin.

Skin-identical fatty acids

Its fatty acid profile is similar to human sebum, which can help reinforce the skin's natural barrier.

Cons and cautions

May clog pores

With a moderate comedogenic rating, lard can trigger breakouts in those prone to acne or congestion.

Not vegan-friendly

As an animal-derived ingredient, it is unsuitable for vegans and those avoiding animal products for ethical or religious reasons.

Best for

  • People with very dry or dehydrated skin
  • Those looking for a traditional, minimal-ingredient moisturizer

Use caution if

  • People with oily or acne-prone skin
  • Vegans and those avoiding animal-derived ingredients

Usage tips

Use a small amount on damp skin to help it spread more evenly and reduce greasiness.
Patch test on a small area before applying to the face, especially if you have sensitive or acne-prone skin.

Safety summary

Lard is generally safe for topical use when properly refined. The main concerns are comedogenicity and ethical considerations. Allergic reactions are rare but possible.

Research notes

Traditional use and anecdotal evidence support lard's moisturizing properties, but modern clinical studies are limited. Its fatty acid composition is well understood and similar to other animal and plant fats used in skincare.

Common label clues

Typical concentration
1% to 30% depending on formulation
Regulatory status
Approved for use in cosmetics in the US and EU under general cosmetic safety regulations. No specific restrictions beyond standard good manufacturing practices.
Common uses
Moisturizers, Barrier creams, Lip balms, Soaps
Environmental note
Lard is a byproduct of the meat industry, so its use in cosmetics can be considered a form of upcycling. However, it is not suitable for those seeking plant-based or synthetic alternatives.

Good to know

  • Lard is sometimes labeled as 'Adeps Suillus' on ingredient lists.
  • Refined lard has a very mild scent and is less likely to cause irritation than unrefined versions.
