Cosmax Introduces pH-Responsive Technology for Hair Repair
Cosmax has developed a new ingredient that repairs damaged hair by responding to changes in pH levels. Called Corelink-S™, the technology reflects a shift toward science-driven haircare that goes beyond surface-level treatment.
Today, many consumers want solutions that restore strength after damage from coloring, perming, and heat styling. As a result, demand for deeper, long-term repair continues to grow.
A research-driven collaboration
Cosmax developed Corelink-S™ in partnership with Seoul National University, combining academic research with industry expertise.
Specifically, the project was supported by the Seoul National University–Cosmax Technology Incubation Center. This interdisciplinary research center focuses on integrating advanced technologies such as AI and data-driven science into beauty and health innovation.
More broadly, this collaboration highlights a growing industry trend. Increasingly, beauty companies are working with research institutions to develop more scientifically validated ingredients.
Addressing growing consumer demand
Recently, consumer demand for effective hair repair solutions has increased. Many people are looking to reverse damage caused by frequent chemical treatments and styling.
In fact, research shows that repairing damaged hair is one of the most important factors influencing haircare purchases. This is especially true for consumers who regularly perm or color their hair.
Because of this shift, interest in high-performance, treatment-focused ingredients continues to rise.
The science behind Corelink-S™
Hair consists mainly of keratin, a protein formed by chains of amino acids. These chains connect through cysteine bonds, which provide strength and elasticity.
However, chemical treatments often break these bonds. As a result, hair becomes weaker, more fragile, and negatively charged.
Corelink-S™ directly targets this damage. Unlike traditional treatments, it penetrates deep into the hair shaft instead of remaining on the surface.
Once inside, the molecule reacts to pH changes. In slightly acidic conditions, it shifts to a positive charge. Then, it binds to negatively charged, damaged areas of the hair.
This process helps reconnect broken bonds and restore the internal structure. As a result, the hair becomes stronger and more similar to its natural, healthy state.
Testing shows that treated hair demonstrates significantly higher tensile strength compared to untreated hair. In addition, the technology is currently pending patent protection.
Enhancing delivery with dual-phase technology
To improve performance, Cosmax developed a delivery system called Bicapture Elixir.
Traditionally, hair oils struggle to deliver active ingredients deep into the hair. This happens because they lack water-based components needed for absorption.
In contrast, Bicapture Elixir combines both oil-based and water-based ingredients. As a result, active ingredients penetrate deeper into the hair structure.
This dual-phase system provides two key benefits. First, it smooths the hair cuticle immediately. Second, it improves tensile strength over time.
Expanding into global markets
Cosmax is continuing to expand its research and global presence. In particular, the company is targeting regions such as Europe and North America.
In these markets, consumers often have finer hair types that are more prone to damage. Therefore, demand for targeted repair technologies is especially strong.
Overall, this strategy reflects a broader trend toward personalized and performance-driven haircare solutions worldwide.
