Ingredient review
Butyrum
INCI: Butyrum
Butyrum is a natural butter that softens and protects skin, but its comedogenic potential depends on the specific plant source.
In plain English
Butyrum is just the fancy INCI name for 'butter' in skincare. It usually refers to plant-based butters like shea, cocoa, or mango butter. These butters are rich in fatty acids that help soften and moisturize the skin by forming a protective layer that locks in moisture. They are common in thick creams, balms, and body butters, especially for dry or rough skin.

Quick decision guide
Useful, but context matters
Butyrum 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.
- Step 1Start with the score, then check the irritation and clogging risk before judging Butyrum.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- 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
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
variesDepends heavily on formula texture, concentration, and the rest of the product.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Butyrum is the Latin term for butter, used in INCI lists to denote a fat derived from plant sources. Common examples include shea butter, cocoa butter, and mango butter. These are solid at room temperature and contain a mix of triglycerides, fatty acids, and vitamins.
How it works
Butyrum works by depositing a thin, oily film on the skin's surface. This film reduces water loss (transepidermal water loss, or TEWL) and helps keep the skin hydrated. The fatty acids also help fill in gaps between skin cells, making the skin feel smoother and softer.
Pros
Intensive moisture
Butyrum provides deep hydration for dry skin, making it ideal for body butters and lip balms.
Natural origin
Derived from plants, it appeals to those seeking natural or organic skincare options.
Cons and cautions
Pore-clogging potential
Some butters, like cocoa butter, have a higher comedogenic rating and may cause breakouts in acne-prone individuals.
Heavy texture
Butyrum can feel thick and greasy, which may not suit oily skin or humid climates.
Best for
- People with dry or very dry skin
- Those looking for a natural, plant-based moisturizer
Use caution if
- Individuals with oily or acne-prone skin, especially if the butter is known to be comedogenic
Usage tips
Safety summary
Butyrum is considered safe for topical use. The main concern is comedogenicity, which varies by source. Allergic reactions are rare but possible. Always patch test new products.
Research notes
Studies confirm that plant butters like shea and cocoa improve skin hydration and barrier function. However, evidence is mostly from ingredient-level studies, not large clinical trials.
Common label clues

- 1-20% depending on product type
- Regulatory status
- Generally recognized as safe for cosmetic use by the FDA and EU CosIng database. No specific restrictions.

Good to know
- Butyrum is a generic term; always check the specific plant source (e.g., shea, cocoa) for comedogenic rating.
- Unrefined butters retain more natural vitamins and scent but may have a stronger odor.
