Rutin, a polyphenol flavonoid glycoside found in citrus and other plants, combines the benefits of quercetin and rutinose. Renowned in cosmetics for its potent antioxidant, antibacterial, and wound-healing properties, it rivals ascorbic acid in efficacy. While studies suggest its potential as a skin-whitener and SPF enhancer, its primary acclaim lies in bolstering the skin’s defense against sun damage through its formidable free radical-scavenging abilities.

Rutin (Wikipedia)

Rutin (rutoside, quercetin-3-O-rutinoside or sophorin) is the glycoside combining the flavonol quercetin and the disaccharide rutinose (α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranose). It is a flavonoid glycoside found in a wide variety of plants, including citrus.
