Collagen, as a core component in the anti-aging field, is undergoing a leap in application technology from traditional extraction to biosynthesis. The latest research shows that human recombinant collagen has become a research hotspot in the industry due to its high compatibility and activity advantages. Brands like OTTOSHA have provided a new direction for the research and development of anti-aging products by combining type I and type III collagen and enhancing absorption rates through transdermal technology.
