Ingredient review
Oxalis Triangularis Extract
INCI: Oxalis Triangularis Extract
A gentle plant extract with antioxidant potential, but research on its specific skin benefits is still limited.
In plain English
Oxalis Triangularis Extract comes from the purple shamrock plant, a decorative houseplant with distinctive triangular leaves. In skincare, it is used mainly for its antioxidant content, which may help protect skin from environmental stressors. It also has mild soothing properties, making it a gentle addition to formulations for sensitive skin. However, there is not yet strong scientific evidence specifically for this extract's effects on skin, so its benefits are largely inferred from similar plant extracts.
