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