On July 31, 2025, the National Institutes for Food and Drug Control (NIFDC) released six draft Technical Guidelines for public consultation, including the Technical Guidelines for the Study of Hair Dye Cosmetics (Trial). In terms of perm hair cosmetics, according to the relevant guidelines, the definition and classification of them have been clarified.

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.

A breakthrough study on the anti-photodamage effects of Gardenia Fructus Extracts, jointly conducted by Hangzhou CIRS KEXIN Biotech Co., Ltd. (CIRS Biotech) and Shanghai Junyu Biotechnology Co., Ltd. (Junyu Group), has been published in Cosmetics, an internationally renowned SCI-indexed journal. The breakthrough study provides scientific validation for the development of photoprotective ingredients and the establishment of its efficacy evaluation systems.

Collaborative research on a hair heatrf damage model, jointly conducted by Hangzhou C&K Testing Technic Co., Ltd. (CIRS Testing) and Amway (Shanghai) Innovation and Science Co., Ltd. (Amway), has achieved significant progress. The findings have been formally published in the internationally authoritative SCI-indexed journal- Journal of Cosmetic Dermatology. This breakthrough study not only provides a novel scientific tool for in-depth exploration of hair heat damage mechanisms but also marks a new level of global recognition for China’s cosmetic efficacy evaluation technology within the international academic community.

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.
