Silkworm Chrysalis Extract
INCI: SILKWORM CHRYSALIS EXTRACT
A gentle, protein-packed extract that helps hydrate and soothe skin, but research is still limited.
In plain English
Silkworm chrysalis extract comes from the cocoon of the silkworm before it becomes a moth. It's rich in amino acids and proteins that can help your skin hold onto moisture and feel smoother. Think of it as a nourishing broth for your skin — it's mild, unlikely to cause breakouts, and works well in hydrating serums or creams.

What it is
A natural extract derived from the chrysalis (pupa) of the silkworm, Bombyx mori. It contains amino acids, peptides, and other nutrients that are used in cosmetics to support skin hydration and comfort.
How it works
The amino acids in the extract act as humectants, drawing water into the outer layer of the skin. The peptides may help support the skin's natural barrier function, reducing water loss and leaving skin feeling softer and more supple.
Pros
Gentle hydration
The amino acids help attract moisture to the skin without causing irritation, making it suitable for sensitive skin types.
Natural origin
Derived from a renewable byproduct of silk production, it appeals to those seeking naturally sourced skincare ingredients.
Cons and cautions
Limited research
Most evidence comes from lab studies or traditional use; there are few high-quality human trials confirming its benefits.
Allergen potential
As an insect-derived ingredient, it may trigger allergic reactions in people with sensitivities to silkworm or other insect proteins.
Best for
- People with dry or dehydrated skin
- Those looking for a gentle, natural humectant
Use caution if
- Individuals with known allergies to silkworm or insect-derived ingredients
