WActive®Prinsepia Ferm


WActive®Prinsepia Ferm is derived from the Prinsepia utilis, native to the high-altitude regions of Yunnan, China. Through advanced biotechnological fermentation processes, this innovative ingredient is created by transforming previously discarded fruit residues into a potent skincare extract. Rich in Prinsepia polysaccharides and over 259 active compounds, including organic acids, phenolic compounds, and coumarins, WActive®Prinsepia Ferm enhances skin elasticity and firmness. It provides exceptional soothing and anti-inflammatory effects, while deeply hydrating the skin and protecting against moisture loss. This powerful ingredient supports overall skin health, leaving the skin balanced, smooth, and visibly rejuvenated.

Upcycled Power:  Prinsepia Utilis Reimagined


Amid the sun-drenched, rugged landscapes of southwestern China, Prinsepia utilis thrives, enduring the harshest climates for over 600 years. 

Revered as both a medicinal food and a natural powerhouse, it has long been celebrated for its skin protecting, healing, and 

hair-enhancing benefits.


Locally, its precious oil is harvested, but the leftover pomace often goes to waste—burned, composted, or used as animal feed. 

At Winkey, we unlock its full potential through a sustainable process of collection, water extraction, and fermentation, transforming 

this byproduct into the potent Prinsepia Ferm.



Evaluation of efficacy

Reduces the level of IL-6 by 37.6% after LPS stimulation.




In vivo test


Improves skin moisturization and hydration by 96.17% in just 8 hours.

Enhances skin firmness and elasticity within 30 minutes.
