Hydrolyzed elastin is a soluble protein derived from animal elastin that has been broken down into smaller peptides, used in skincare to improve skin feel, hydration, and surface smoothness. It functions primarily as a film-forming conditioning agent rather than a deep-penetrating active.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis | Rare | Protein hydrolysates can occasionally trigger sensitization in predisposed individuals. |
| Skin irritation or redness | Rare | Mild transient irritation reported in sensitive skin. |
| Contact urticaria | Very rare | Hypersensitivity reactions to animal-derived protein hydrolysates have been documented in isolated cases. |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
