Introduction
Retinol is the undisputed gold standard in anti-aging, a top-tier active ingredient celebrated by experts worldwide. However, its effectiveness has always been shadowed by a list of well-known challenges: notorious instability, potential for irritation, and complex penetration and conversion pathways. For years, brands have worked to overcome these issues with technologies like standard liposomal encapsulation. But as the market has shown us, these problems have not been truly solved.
At Yanzhimountain, our new R&D center is dedicated to pushing the boundaries of what's possible, with molecular delivery technology being a key focus. We saw the persistent retinol dilemma as a challenge we were uniquely equipped to accept. The result of this endeavor is a product we are proud to introduce: DualLipol Retinol (10%). While the name may sound straightforward, the patent-pending technology behind it is anything but.

The innovative dual-layer structure of DualLipol Retinol, engineered for maximum stability and intelligent, temperature-responsive release.
A Smarter Encapsulation for Superior Performance
We have developed an innovative "dual-layer intelligent thermo-sensitive encapsulation system." This technology enhances the stability of the entire liposome by adding an outer layer of a macromolecular polymer. The ingenuity lies in our use of a thermo-sensitive material, which allows this protective structure to adapt to changes in temperature. This makes our retinol uniquely resilient to environmental challenges, ensuring it reaches the skin with its potency intact.
"Our goal was to create a retinol that formulators could trust and consumers could love. The DualLipol system achieves this by creating an intelligent shield that protects the retinol until the moment it's needed, delivering maximum efficacy without the traditional drawbacks."

Unprecedented Stability: Surviving the Heat
In standardized testing, we compared DualLipol Retinol against various encapsulated retinols on the market. After one month under high-heat conditions (45°C), the results were definitive. Unopened, our product showed less than 3% degradation. Opened, it was under 10%. In stark contrast, all competitor products showed degradation of over 50%.
Intelligent Release: Efficacy Guaranteed
A common concern with robust encapsulation is whether the active can be effectively released on the skin. Comparative testing shows that DualLipol Retinol has a significantly higher and more sustained release profile than control products, ensuring that its superior stability translates directly to superior performance.
Uncompromised Potency: The Power of Pure Retinol
Our encapsulation technology protects the retinol molecule without hindering its biological activity. In-vitro tests confirm that DualLipol Retinol delivers the same powerful effects as an equivalent concentration of pure retinol. It was shown to significantly increase the synthesis of Type I Collagen and effectively inhibit elastase activity by 14.87%, proving its potent firming and anti-wrinkle efficacy.
The End of Irritation: Clinically Proven Gentleness
Using the HET-CAM (Hen's Egg Test - Chorioallantoic Membrane) assay, we confirmed the exceptional safety profile of our product. Both a low concentration (1%) and a high concentration (5%) of DualLipol Retinol were found to be completely safe and non-irritating.

A Formulator's Advantage: Effortless Suspension
Beyond its performance benefits, DualLipol Retinol offers a significant advantage in formulation. The macromolecular structure of its outer shell allows it to self-suspend within certain limits in aqueous systems. This enhances its dispersibility and can reduce or eliminate the need for additional suspending agents, simplifying the formulation process.
Conclusion
DualLipol Retinol is not just another encapsulated retinol; it is a complete solution to the long-standing challenges of retinol formulation. By delivering unparalleled stability, intelligent release, uncompromised efficacy, and a zero-irritation profile, it empowers brands to create next-generation retinol products that are both powerful and exceptionally gentle. The new standard for retinol has arrived.
