Objective:Refer to a lot of literature,combined with the mask Bute point and the market essence formula,determine the whitening hydrogel mask composition,and prepare the whitening hydrogel mask,at the same time to determine the mask stability,PH value.Changes in surface pigment,deep pigment,superficial wrinkles,deep wrinkles,fine lines,red areas and adverse reactions of the subjects before and after using the whitening hydrogel mask were detected by cloud mirror to evaluate the efficacy and safety of the whitening hydrogel mask.Methods:1.The preparation of whitening hydrogel mask essenceBy referring to a lot of literature,combined with the mask butt point and the mask essence formula on the market,through orthogonal test to optimize the mask essence formula,get the best formula,and evaluate the heat resistance,cold resistance and PH value of the mask.2.Observation of Facial Mask efficacySixty subjects conforming to the Natron standard were selected as the study subjects and observed from September 2022 to December 2022.The subjects were divided into two groups by random number method: control group(using Natural hall mask)and experimental group(using whitening hydrogel facial mask).Use the mask for 15 to 20 minutes at a time,and then clean your face with water to avoid residue.The mask was applied once every 3 days for 57 days.CBS cloud mirror was used to record the horizontal changes of skin pigment,deep pigment,superficial wrinkles,deep wrinkles,fine lines and red areas before and after using the mask.Meanwhile,the occurrence of adverse reactions was recorded to complete the project.Statistical software SPSS24.0 was used for data analysis.Results:(1)The optimal formula of facial mask essence is: glycerin 10%,sodium hyaluronate0.1%,recombinant human collagen 2%,red myrrh 0.5%,niacinamide 4%,trantranic acid2%,rose hydrosol 1%,ultra-pure water to 100%.When using,fully contact 40 ml mask liquid with mask cloth for 1-2min to make the mask crystal clear,soft and smooth.This mask has uniform texture,good heat and cold resistance,and PH value is in line with the cosmetic industry standard《QB/T 2872-2017》.(2)Intra-group comparison: After using facial mask,the levels of surface pigment,deep pigment,superficial wrinkles,deep wrinkles,fine lines and red areas of facial skin in all groups were significantly lower than those in the same group,and the differences were statistically significant(P<0.05).(3)Comparison between groups: After using the mask,the levels of surface pigment,deep pigment and red area of facial skin in experimental group were lower than those in control group,and the difference was statistically significant(P<0.05).There was no significant difference in the level of superficial wrinkles,deep wrinkles and fine lines between the two groups after using the facial mask(P>0.05).Conclusion:Whitening hydrogel mask not only has certain whitening effect,but also can effectively improve skin aging and inflammation.
