As the global market for efficacy-driven skincare continues to expand, consumers are increasingly seeking cosmetic ingredients that deliver high activity, strong safety profiles, and scientifically validated efficacy.
For beauty brands, developing differentiated active ingredients has become an important pathway to building long-term technological advantages. Among functional cosmetic actives, peptides have emerged as a key area of interest for leading brands due to their targeted mechanisms, defined biological activity, and multifunctional benefits.
As more brands explore peptide-based solutions, developing proprietary and differentiated peptide technologies has become a new challenge for the industry.
To address this growing demand, Winkey Technology has established four major directions for peptide innovation, covering advanced discovery technologies, cyclic peptide development, PDC technology, and PFAS-free peptide solutions.
01 | Faster R&D: Dual Technology Platforms Accelerate Global Peptide Innovation
Traditional peptide development often faces challenges such as long development cycles, low screening efficiency, and difficulties in identifying precise biological targets.
To overcome these limitations, Winkey Technology has introduced methodologies inspired by pharmaceutical R&D into the field of cosmetic peptides.
The company has established two advanced technology platforms:
Together, these platforms create an integrated development workflow covering:
High-Throughput Screening → Precision Molecular Design → Rapid Efficacy Validation
This closed-loop R&D model significantly improves the efficiency of discovering and commercializing innovative peptide molecules.
Based on this technology system, Winkey has built a library of 300+ innovative peptide molecular structures and completed the registration filing of 16 new peptide cosmetic ingredients, ranking No. 1 in China¹.
Representative innovative ingredients include globally pioneering peptide structures such as:
Erasin — Targeted Collagen-Promoting Peptide
Weilingyu — Advanced Skin-Repair Peptide
Weishuyin — 15-Minute Rapid Soothing Peptide
Weiyusu — Immune-Anti-Aging Peptide
Core Value
Winkey provides partners with differentiated active ingredients featuring innovative molecular structures, patent protection, and comprehensive scientific evidence, helping brands move beyond homogeneous competition.
Beyond existing ingredient solutions, Winkey can also develop new peptides from the ground up through customized R&D, enabling brands to build stronger scientific and technological differentiation.
02 | More Advanced Technology: Cyclic Peptides Break Through Traditional Peptide Limitations
Some linear peptides face challenges in cosmetic applications, including enzymatic degradation, limited skin penetration, and difficulties in incorporating them into oil-soluble formulations.
To address these challenges, Winkey Technology has moved beyond the conventional approach of simply modifying peptides with acidic groups and developed a new generation of peptide solutions based on cyclic peptide technology.
By connecting the two ends or selected side chains of a linear peptide sequence to form a cyclic structure, cyclic peptides can offer enhanced enzymatic stability, skin penetration potential, and targeting precision.
Winkey Super Cyclic Peptide Library
Winkey has established its Super Cyclic Peptide Library, which currently contains dozens of innovative cyclic peptide candidates covering multiple structural types, including:
Monocyclic peptides
Bicyclic peptides
Multicyclic peptides
Representative projects include:
These innovative structures are designed to provide advantages such as enhanced skin penetration, improved stability, and longer-lasting activity, offering an alternative to the limitations associated with traditional acid-modified peptide technologies.
Winkey recently unveiled this technology portfolio at PCHi 2026, presenting dozens of cyclic peptide projects designed to address a broad range of functional skincare applications.
Core Value
As interest in cyclic peptides continues to grow, Winkey's extensive scientific and technological pipeline enables partners to access diverse cyclic peptide molecules and customized solutions for next-generation skincare formulations.
03 | Classic Ingredients, Reimagined: PDC Technology Brings New Potential to Established Actives
PDC (Peptide-Drug Conjugate) technology was originally developed for pharmaceutical applications.
It typically combines three components—a targeting peptide, an active molecule, and a linker—to create synergistic effects through molecular conjugation.
Winkey Technology is among the early cosmetic ingredient companies to introduce this advanced technology into the cosmetics industry.
In 2023, Winkey introduced its first cosmetic ingredient developed using PDC technology, Caffeoyl Hexapeptide-9, followed by a series of innovative ingredients including Nicotinoyl Tetrapeptide-30.
The value of PDC technology lies in its ability to reimagine established hero ingredients.
Through molecular conjugation, brands can upgrade ingredients that have been developed and recognized over many years into new molecules with enhanced functional potential and a stronger technological proposition.
This approach allows brands to maintain consumer recognition of their signature ingredients while simultaneously creating new technological differentiation and higher barriers to competition.
In other words, PDC technology can help brands upgrade their hero ingredients and bring new vitality to classic actives.
Core Value
PDC technology enables brands to preserve the value of their established hero ingredients while exploring next-generation molecular structures and enhanced functional performance, creating stronger technological differentiation.
04 | Greener and More Compliant: PFAS-Free Peptides for Global Regulatory and Sustainability Needs
As global regulations surrounding PFAS (per- and polyfluoroalkyl substances) continue to become increasingly stringent, Winkey Technology has proactively upgraded the manufacturing processes of dozens of its leading peptide ingredients toward more sustainable and compliant production.
These improvements are designed to support compliance with relevant global regulatory requirements, including REACH registration and applicable FDA standards.
Several Winkey peptide products, including Palmitoyl Pentapeptide-4 and Acetyl Hexapeptide-8, are now available with PFAS-free manufacturing processes, supporting brands seeking peptide ingredients aligned with evolving PFAS regulatory requirements.
Core Value
PFAS-free peptide solutions can help brands reduce regulatory verification costs and testing timelines, providing a more efficient ingredient solution for cosmetic products targeting international markets.
