Functional Use in Cosmetics and Personal Care

Astaxanthin is a lipid-soluble ketocarotenoid with intense antioxidant power and visual pigmentation benefits. Due to its rich red hue and high radical-scavenging efficiency, it is suited for use in antioxidant-focused, visually distinct cosmetic products. Its oil solubility makes it ideal for emulsions, serums, and lipid-enriched delivery systems.

• Antioxidant Efficacy: Supports skin defense against oxidative and environmental stress
• Natural Tint: Adds coral to reddish-orange tone in oil-based products
• Photostability Agent: Enhances protection in sun care and after-sun applications
• Formulation Enrichment: Enhances antioxidant claims in clean or performance care lines

Astaxanthin is often applied in facial oils, skin defense balms, antioxidant boosters, tinted emulsions, and protective sun care blends. Delivered in bulk format with traceable origin and full documentation.
