Summary

Antioxidant Skin Brightening Collagen Stimulating Antiseptic Antibacterial Oil Balancing Astringent Moisturizing Exfoliating (Aids) Skin Conditioning

Science

Mechanism of Action

This extract functions as a powerful antioxidant, neutralizing free radicals and protecting skin protein structures from oxidative damage induced by UV exposure and environmental stressors. Its high vitamin C content actively stimulates collagen production, contributing to a reduction in fine lines and the restoration of a more even skin tone. Additionally, its natural tannins offer astringent properties, effectively tightening pores and regulating excess sebum. The extract also exhibits antiseptic and antibacterial qualities, which are beneficial for managing problem skin and reducing pore clogging, while aiding in gentle exfoliation for clearer skin.

Safety Profile

CIR Status
Not reviewed
Sensitization risk Low

Psidium Guajava Fruit Extract is widely regarded as safe for use in cosmetic products and rarely induces allergic reactions; however, a preliminary patch test is recommended for individuals with highly sensitive skin. It aligns with safety standards set by various international regulatory bodies, including the European Union Cosmetics Directive. It's important to differentiate that available acute and chronic toxicity studies refer specifically to guava leaf extract and oral consumption in rodents, not directly to the fruit extract in topical skincare.
