Eugenol rutinoside is primarily used in cosmetics and skincare products for its antioxidant and anti-inflammatory properties. It helps protect skin from oxidative stress, reduces redness and irritation, evens skin tone by inhibiting melanin production, and supports collagen synthesis for firmer, more youthful-looking skin. Suitable for moisturizers, sunscreens, and dark spot reduction products. Also explored in oral care formulations due to mild antimicrobial effects, in natural fragrance blends for a subtle spicy-floral note, and in functional foods and nutraceuticals owing to enhanced stability and bioavailability compared to free eugenol.
