Kolmar Korea has developed what it says is South Korea's first dissolvable hyaluronic acid skincare powder, offering a potentially gentler alternative to conventional spicules used to enhance ingredient absorption.
The cosmetics manufacturer said Thursday it had secured a patent for the technology, which turns hyaluronic acid, a widely used moisturizing ingredient, into microscopic needle-shaped crystals that dissolve upon contact with moisture.
Conventional spicules, typically derived from marine sponges, help active ingredients penetrate the skin by creating microscopic stimulation. However, their water-insoluble structure can cause irritation and require rinsing after use, according to Kolmar Korea.
After four years of research, the company developed a process to form hyaluronic acid into pointed crystals measuring approximately 250 micrometers in length.
Unlike conventional spicules, the new particles dissolve as they are rubbed into the skin, potentially reducing irritation while maintaining their intended ingredient-delivery function.
In company tests, the formulation showed up to 62 percent better sustained moisturizing performance than conventional creams, although Kolmar Korea did not disclose the testing conditions.
The company plans to incorporate the technology into skincare products containing ingredients such as retinol, centella asiatica extract and allantoin.
It also aims to expand applications beyond powder formulations to serums, creams and facial mists.
