ABSTRACT: In view of the increasing sensitivity of consumer skin in recent years, cosmetics containing Artemisia annua extract was tested to evaluate its effectiveness in repairing sensitive skin. Through the experiment of xylene-induced ear swelling in mice, it was found that the inhibition rates of ear swelling in mice induced by xylene in three groups of cosmetics containing Artemisia annua extract reached 60.40%, 73.36% and 74.01%, respectively, close to the positive drug group. Twenty-five sensitive skin volunteers were selected for human clinical trial, and the skin TEWL value, cuticle hydration degree and skin heme (ultra-high concentration) were tested. The results showed that using cosmetics containing Artemisia annua extract for four weeks could effectively increase the hydration degree of cheek cuticle by 63.90% and reduce transepidermal waterloss (TEWL) by 21.51%. The skin heme (ultra-high concentration) decreased by 69.14% and the affected area decreased by 77.47%. The results show that the cosmetics containing Artemisia annua extract can inhibit inflammation, repair skin barrier, improve damaged skin, and reduce redness and other sensitive skin symptoms.
