flavonoids
Flavonoids are a large class of plant-derived polyphenolic compounds commonly used in skincare extracts for antioxidant, soothing, and anti-aging support. In cosmetics they are typically present as part of botanical extracts rather than as a single purified ingredient. They help reduce oxidative stress and may support brightening and barrier resilience, depending on the specific flavonoid source.

Risks & Warnings
Generally low risk at cosmetic use levels, but the class is chemically diverse and some botanical sources may cause contact allergy or irritation in sensitive users. Stability and efficacy vary widely by specific flavonoid and formulation. In very high concentrations some flavonoids may be cytotoxic in vitro, but this is not typical of cosmetic use.
