Triterpenoids are a class of naturally derived plant compounds (e.g., from centella, licorice, or birch) used in skincare for their antioxidant, anti-inflammatory, and barrier-supporting properties. They are generally included to calm irritation and support skin repair.

Mild skin irritation or redness | Uncommon | Typically transient, more likely in sensitive skin or at higher concentrations. |
Allergic contact dermatitis | Rare | Possible sensitization to specific botanical-derived triterpenoids. |
