Hydrolyzed Sponge
INCI: Hydrolyzed Sponge
Hydrolyzed Sponge is a gentle, marine-based ingredient that may help calm irritated skin and support moisture retention, though research is still emerging.
In plain English
Hydrolyzed Sponge is made from sea sponge that has been broken down into smaller pieces so it can be used in skincare. It is thought to help soothe redness and keep skin hydrated by forming a light, protective film on the surface. Think of it like a gentle, ocean-derived helper for sensitive or stressed skin.

What it is
Hydrolyzed Sponge is a natural ingredient derived from marine sponges. The sponge material is hydrolyzed (broken down with water and enzymes) into smaller peptides and polysaccharides that can be incorporated into cosmetic formulas.
How it works
In a cosmetic product, Hydrolyzed Sponge is believed to work by depositing a thin, film-forming layer on the skin. This layer can help reduce water loss (transepidermal water loss, or TEWL) and may have a mild anti-inflammatory effect, making it useful for calming irritation.
Pros
Gentle soothing potential
Hydrolyzed Sponge is often included in products for sensitive or post-procedure skin because it may help calm redness without causing stinging or irritation.
Lightweight hydration support
It forms a thin film on the skin that can help lock in moisture, making it a good addition to lightweight lotions or serums for normal to oily skin types.
Cons and cautions
Limited research backing
Most evidence for Hydrolyzed Sponge comes from ingredient supplier studies or traditional use, with few independent clinical trials confirming its benefits.
Potential allergen risk
As a marine-derived ingredient, it may trigger reactions in people with shellfish or sponge allergies, though such cases are rare.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, natural soothing ingredient
Use caution if
- Individuals with known allergies to marine or sponge-derived ingredients
