唇部皮肤生理参数的多维度分析和研究OA北大核心CSTPCD

To investigate the basic state of lip skin in subjects of different regions,ages and genders,multi-dimensional analysis and research on lip physiological parameters were conducted,and the main factors affecting lip skin traits through the intervention of lip oil on lip skin were explored.Subjects(73 aged 18-35 years old,50 aged 35-60 years old,and 55 males,68 females)in East China(73)and North China(50)were determined by noninvasive evaluation method.Eight skin physiological parameters of moisture content,TEWL,gloss,elasticity,L*a*b* value and texture of the lower lip were measured.The results of this study show that the trans epidermal water loss(TEWL)values of 51.99±17.37,L* values of 51.99±8.83,b* values of 15.40±1.56 and texture values of 15.10±6.43 in the East China group are significantly higher than those in the North China group(P<0.05).The moisture content(56.82±12.63)and skin elasticity(0.78±0.18)of the 35-60 years old group are significantly higher than those in the 18-35 years old group(P<0.05).The TEWL value of the basal state of the lips(52.08±17.68)in the male group is significantly higher than that in the female group(43.48±16.03)(P<0.05).Through the intervention of lip oil on the skin of the lips,compared with the basic state,the moisture content of the lips of the subjects after using the lip oil first decreases and then gradually increases.TEWL first decreases significantly and then gradually increases.The gloss,elasticity and texture are first increased and then decreased.The change in skin color(L*a*b* value)is not significant.In summary,the physiological parameters of the subjects'lip skin are not only affected by the regions,ages and genders,but also related to the basic state of the subjects'lips and the frequency of lip products usage.
