摘要

Acupuncture is increasingly used to improve facial skin conditions. Contact needle technique (CNT) is a traditional Japanese acupuncture method. This pilot study aimed to investigate the acute effect of CNT by evaluating changes in capillaries and improvement in skin moisture content. Fifteen women participated in this study; they received CNT to the right side of their face for 30 min. The primary outcomes were the change in the skin moisture content and the shapes of the capillaries before and after CNT. Skin moisture content significantly increased after treatment. The number of blood vessels increased after treatment. We also observed that the capillaries became thicker, more numerous, and more active after treatment. We propose that the skin condition can be influenced and improved by CNT.
