Ingredient review
Silkworm Chrysalis Oil
INCI: Bombyx Mori Chrysalis Oil
A unique, fatty-acid-rich oil that moisturizes and may support skin barrier function, but research is still limited.
In plain English
Silkworm chrysalis oil is pressed from the pupae of silkworms. It contains a mix of fatty acids (like linoleic and oleic acid) and antioxidants that help soften and condition the skin. Think of it as a lightweight, nourishing oil similar to argan or jojoba, but from an insect source. It's not heavily studied in humans, so its benefits are mostly based on its composition and traditional use.

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 Silkworm Chrysalis Oil.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
moderateMay be fine for many users but deserves caution if you are breakout-prone.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A natural oil extracted from the chrysalis (cocoon stage) of the silkworm Bombyx mori, typically a byproduct of silk production.
How it works
The oil's fatty acids (especially linoleic acid) help replenish the skin's natural lipid barrier, reducing water loss and keeping skin soft. Antioxidants like vitamin E may help protect against environmental stress.
Pros
Rich in skin-friendly fatty acids
Linoleic and oleic acids help maintain the skin barrier and keep moisture locked in, which is especially helpful for dry or dehydrated skin.
Upcycled ingredient
Made from a byproduct of silk production, so it supports a circular economy and reduces waste.
Cons and cautions
Limited scientific backing
Most evidence comes from traditional use and lab studies; there are few high-quality human trials confirming its benefits.
Moderate comedogenic risk
May clog pores for some people, especially those with oily or acne-prone skin, so patch testing is recommended.
Best for
- People with dry or normal skin looking for a natural moisturizer
- Those interested in sustainable byproduct ingredients
Use caution if
- Vegans or those avoiding animal-derived ingredients
- Acne-prone individuals (moderate comedogenic risk)
Usage tips
Safety summary
Silkworm chrysalis oil is considered safe for topical use in cosmetics at typical concentrations. Allergic reactions are rare but possible. Avoid if you have a known allergy to silkworms or insect-derived products.
Research notes
Research is preliminary. Lab studies suggest antioxidant and moisturizing properties, but human clinical trials are scarce. Most evidence is based on the oil's fatty acid profile and traditional use in East Asian skincare.
Common label clues
