Encapsulated Pyrrole Composite Whitening Agent: A Smart, Controlled-Release Solution for Precise Spot Fading
The encapsulated pyrrolidone composite whitening agent is centred on the concept of ‘multi-target synergy + gentle yet effective,’ utilising nano-liposome encapsulation technology to combine whitening ingredients such as pyrrolidone glucoside, niacinamide, and tranexamic acid. This addresses the challenges of traditional whitening agents, such as strong irritation and poor stability, achieving a comprehensive whitening process through ‘inhibition-blocking-metabolism.’
Core Technology and Efficacy Upgrades
1. Smart-Release System: Nanoliposomes (particle size 80–120 nm) protect active ingredients from oxidation while enabling 24-hour sustained release, reducing skin irritation (redness incidence reduced by 75%);
2. Multi-functional synergistic whitening: Pyranoglucoside inhibits tyrosinase activity (inhibition rate of 82%), niacinamide blocks melanin transport (reduction of 65%), and tranexamic acid accelerates metabolism (increase of 48%). After 8 weeks of using an essence containing 2% composite whitening agent, the area of dark spots decreased by 45%;
3. Anti-inflammatory repair support: Added Centella asiatica extract to reduce inflammatory reactions during the whitening process, with a 90% suitability rate for sensitive skin.
Scene-specific application guidelines
- High-end whitening serum: Recommended addition rate of 1%-3%, paired with vitamin C ethyl ether, enhancing whitening efficacy by 55%;
- Spot-fading cream series: Formulated with retinol (total concentration 2.5%), it improves uneven skin tone and enhances radiance by 39%;
- Sunscreen Enhancement Products: Incorporate into sunscreen (0.8% concentration) to prevent sunburn and sunspots, increasing SPF value by 25%;
- Body Whitening Care: Formulated into body lotion (1.5% concentration) to improve joint darkening, increasing skin whiteness by 32%.
