Developing Criteria for Asian Facial Skin Health Status Based on a Non-Invasive Skin Test: The Delphi Process.

Objective: We aimed to develop a set of facial skin health criteria, combined with skin characteristics, and then determine two levels of skin condition and skin problems.
Methods: Through a literature study and group discussion, an expert consultation index system was initially formed. The Delphi method was used to conduct two rounds of expert opinion consultation. The index was revised, supplemented and reduced based on the experts' ratings and feedback, and the expert score was calculated. The authority and enthusiasm of the experts and the coordination of the expert opinions finally resulted in a new facial skin Health evaluation index system.
Results: The first-level indicators are skin problems and skin condition, the second-level indicators are detailed descriptions, and the third-level indicators are indicators that can be measured by an instrument.
Conclusion: The construction of this system can be used to quantitatively evaluate the health status of facial skin with the help of commonly used skin measuring instruments. This scientific and reasonable facial skin health evaluation index system allows people to have an objective and accurate understanding of their own facial skin health and to gradually improve their facial skin health under monitorable conditions.
