On April 15, 2026, China’s NIFDC published two trial technical guidelines for hair dye cosmetics, clarifying their scope of application and core requirements for research and quality control. CIRS Group provides a comprehensive interpretation of the key points of both guidelines to help cosmetic enterprises quickly capture compliance essentials and accurately grasp core requirements.
Today, let’s talk about tear trough and lacrimal groove evaluation. Currently, many skin care products claimed that they could mitigate the tear trough and the lacrimal groove. Actually, tear trough and lacrimal groove are two different periorbital issues. Sometimes they conflated, likely because they often coexist.
Two-photon microscopy (TPM), a high-resolution three-dimensional imaging technology based on nonlinear optical effects, has demonstrated significant application potential in the field of cosmetic efficacy evaluation in recent years. Its core advantages lie in its non-invasive, in vivo, in situ, label-free real-time imaging capability, enabling deep observation of dynamic changes in cells and the extracellular matrix within skin tissue. This provides a scientific basis for evaluating the safety and efficacy of cosmetics.
