Acetyl Tripeptide-2 is a synthetic tripeptide used in cosmetic formulations for its purported skin-firming and anti-aging effects, often promoted for improving skin elasticity and reducing signs of sagging. Evidence for its efficacy is largely supplier-based and limited.
| Reported effect | How often | Notes |
|---|---|---|
| Mild skin irritation or redness | Rare | Peptides are generally well tolerated; localized irritation may occur in sensitive individuals. |
| Contact dermatitis or allergic reaction | Very rare | Hypersensitivity to the peptide or accompanying formulation excipients is uncommon. |
