Astringin is primarily used in skincare and cosmetic formulations due to its antioxidant and anti-inflammatory properties. It helps protect the skin from oxidative stress caused by environmental factors like UV radiation and pollution. Its ability to support skin barrier function makes it suitable in anti-aging products, where it may reduce the appearance of fine lines and improve skin elasticity. Astringin is also investigated for its potential in soothing sensitive or irritated skin, making it a valuable ingredient in gentle cleansers, toners, and serums. Additionally, it has shown interest in oral care products for its astringent and antimicrobial effects, contributing to improved gum and oral tissue health.
