[0139] Experiment 1 The hyaluronidase inhibition rate (%) of the freeze-dried powder of each embodiment and comparative example was tested according to T / JSRH 003-2023 "Hyaluronidase inhibition method for anti-allergic activity test of cosmetic raw materials".
[0140] Experiment 2 Recruit a number of volunteers, aged 30-40, female, in groups of 10.
[0141] The volunteers were tested on their cheeks using a multi-probe skin testing system, CK-Tewameter™ Hex, to obtain the initial transepidermal water loss rate, and the average value was taken for each group.
[0142] The volunteers applied 3 ml of freeze-dried powder to their faces every day. The freeze-dried powder covered the skin for 8 hours and then immediately washed it off with makeup remover oil and water after 8 hours. No skin care products were used during the experiment.
[0143] After continuous application of freeze-dried powder for 30 days, the cheeks were tested using the multi-probe skin testing system CK-Tewameter™ Hex to obtain the 30-day transepidermal water loss rate, and the average value for each group was taken.
[0144] The specific experimental data of Experiment 1-2 are shown in Table 1.
[0145] Table 1 According to the comparison of the data of each example and the comparative example in Table 1, the hyaluronidase inhibition rate of each example is significantly higher than that of each comparative example, which shows that the freeze-dried powder of each example has better soothing effect and can better soothe the skin, so that the sensitive skin is not easy to appear allergic phenomenon after long-term use of the freeze-dried powder.
[0146] The transdermal water loss rate (%) of each example cosmetic after 30 days is lower than the initial transdermal water loss rate (%), which proves that each example has the effect of promoting skin barrier repair, while the transdermal water loss rate (%) of each comparative example cosmetic after 30 days is higher than the initial transdermal water loss rate (%), which proves that long-term use of each comparative example not only is difficult to promote skin barrier repair but also leads to further damage to the skin.
[0147] In summary, after adding the skin conditioner composed of mucuna extract, grifola extract and eupatorium extract in the freeze-dried powder, the skin can be well soothed, and the skin repair can be promoted, so that the freeze-dried powder is not easy to affect the skin health after long-term use, and can well meet the needs of sensitive skin consumers.
[0148] The specific embodiments are only an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the present specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.
