Hydrolyzed Sponge is derived from freshwater sponges (typically Spongilla) and contains microscopic silica spicules that create micro-channels in the skin, providing mechanical exfoliation and enhancing penetration of accompanying actives. It is often used in spicule-based serums and masks for skin renewal and to improve product absorption.
| Reported effect | How often | Notes |
|---|---|---|
Tingling or prickling sensation | Common | Caused by spicules penetrating the skin surface; usually transient after application. |
Redness/erythema | Common | Temporary mild irritation following use, typically resolving within hours to a day. |
Dryness or flaking | Uncommon | Related to the exfoliating action, more likely with overuse. |
Contact irritation or sensitivity reaction | Uncommon | May occur in those with sensitive or compromised skin barriers. |
Allergic contact dermatitis | Rare | Hypersensitivity to the marine/sponge-derived material. |
