What Is Sus Extract?
Sus Extract is a topical ingredient derived from the skin of the domestic pig, known scientifically as Sus scrofa. Rich in naturally occurring collagen, peptides, amino acids and small amounts of lipids, the extract is valued for the way these components mirror some of the building blocks found in human skin. Its cosmetic use can be traced back to the search for affordable collagen alternatives in the late twentieth century, when manufacturers began experimenting with animal by-products to boost skin feel and hydration in creams and masks.
The ingredient is typically produced by gently breaking down pig skin through enzymatic or acid hydrolysis. This process separates the collagen and supporting proteins from the tougher connective tissue, then concentrates and purifies them into a water-soluble extract. The resulting liquid or powder is easy to blend into water-based or emulsified formulas.
You will most often see Sus Extract listed on the ingredient label of hydrating sheet masks, anti aging serums, rich facial moisturizers, body lotions and occasional leave-on treatments aimed at improving skin smoothness and elasticity.
Sus Extract’s Cosmetic Benefits/Uses
In formulations Sus Extract performs a single, well-defined role: skin conditioning. It helps bind water to the surface of the skin, giving an immediate feeling of softness and improved elasticity, while its film-forming proteins can create a light, breathable layer that reduces transepidermal water loss. Over time this can leave the complexion looking plumper and better hydrated, making the ingredient especially attractive in products that target dryness and early signs of aging.
Who Can Use Sus Extract
Sus Extract is generally well tolerated by most skin types, especially normal, dry and mature skin that benefit from added hydration and a light protein film. Combination skin can also make good use of it when the formula is not overly rich. Those with very oily or acne-prone skin may find heavier products containing the extract feel too occlusive and could prefer lighter textures.
Because the ingredient is sourced from pig skin it is not suitable for vegans or vegetarians. Consumers who follow kosher or halal guidelines may also wish to avoid it for cultural or religious reasons.
No specific data suggest that Sus Extract poses a risk to pregnant or breastfeeding women when applied topically. That said this is not medical advice and anyone who is pregnant or nursing should have their healthcare provider review any skincare product they plan to use just to be on the safe side.
The extract is not known to cause photosensitivity so it does not make the skin more prone to sunburn. Normal daily sun protection practices remain sufficient.
Potential Side Effects/Adverse Reactions
Side effects and reactions to topical Sus Extract can vary from person to person. The following is a list of potential issues yet they are uncommon and most users will not experience them when the ingredient is properly formulated and preserved in a finished cosmetic product.
- Allergic contact dermatitis for individuals sensitive to pork proteins
- Mild redness or stinging in very sensitive skin
- Breakouts or clogged pores in those already prone to acne when used in heavy creams
- Unpleasant odor if the product has degraded or is poorly preserved
- Contamination risk if manufacturing standards are not followed leading to irritation or infection
If any of these effects occur stop using the product and seek guidance from a qualified healthcare professional.
Comedogenic Rating
Rating: 2/5
Sus Extract is mostly water soluble with only trace lipids, so on its own it is unlikely to clog pores. The mild film it forms can feel slightly occlusive in richer creams which nudges its rating up from a 1 to a 2. Formulas that pair the extract with heavy oils or butters are more likely to contribute to congestion than the extract itself.
Overall it is usually fine for people who are prone to acne or breakouts as long as the finished product has a light, non greasy base. Anyone extremely sensitive to occlusive layers may want to choose gel or serum formats instead of thick balms.
Comedogenicity can also be influenced by concentration and the rest of the ingredient deck, so judging the entire formula is more reliable than focusing on Sus Extract alone.
Summary
Sus Extract conditions the skin by drawing in water, binding it at the surface and laying down a breathable protein veil that helps reduce moisture loss. This combination leaves skin feeling softer, smoother and temporarily plumper which is why you will see it in hydrating masks, serums and moisturizers.
The ingredient sits in a niche corner of the market. Some formulators appreciate its collagen rich profile and affordability while others bypass it due to ethical, cultural or regulatory preferences, so it has never become a mainstream superstar.
When sourced and preserved correctly Sus Extract is considered safe for topical use with only rare reports of irritation or allergy. As with any new skincare ingredient it is wise to patch test a fresh product before applying it to larger areas just to make sure your skin agrees with it.
