Study On Skin Physiological Function Of Normal Infants

Background The skin is a multifunctional organ that plays an important role in protecting the body from external disturbances and maintaining the homeostasis and body temperature regulation of water and electrolytes.Physiological function indicators of the skin,such as skin cuticle hydration,skin surface p H,melanin and hemoglobin,etc.,reflect the function of the skin cuticle barrier,which can be used to effectively assess the health status of the skin and the resistance to exogenous invasion,and more and more people are concerned about it.Objective The aim of this study was to detect skin physiological function indicators in infants and young children,to analyze the differences between different ages,genders and different parts,to explore the physiological characteristics of infant skin and to provide an effective basis for infant skin care.Methods A total of 96 healthy volunteers were included,divided into two age groups of 0-1 years old and 1-2 years old,including 20 males in the 0-1 age group and 26females;20 males in the 1-2 age group,female 26 people.Non-invasive skin physiology testing equipment was used to detect skin physiology indexes such as skin water content,skin surface p H,melanin and hemoglobin in five parts of the forehead,cheeks,upper limbs,abdomen and lower limbs.SPSS16.0 data statistics software was used to analyze the differences between different ages,genders and different parts.Results In the 0-1 age group,males had the highest water content in the stratum corneum,followed by cheeks and lower limbs(P<0.05);females had the highest water content in the stratum corneum.In the 1-2 age group,males had the highest water content in the stratum corneum,followed by the upper limbs and the lowest in the abdomen(P<0.05).Women also had the highest water content in the forehead stratum corneum,followed by the cheeks and upper limbs(P<0.05)..The water content of the stratum corneum of the forehead and cheek skin of women in the 1-2 age group was higher than that of the 0-1 age group(P<0.05).In the 0-1 age group,the surface of the female forehead had the highest p H and the abdomen was the second(P<0.05).The surface p H of the forehead and upper limb skin of males in the 0-1 age group is higher than that of the 1-2 age group.The levels of melanin and hemoglobin in the abdomen of the 0-1 age group and the 1-2 age group were higher than those of the male(P<0.05).In the 0-1 age group,the male forehead had the highest melanin content,followed by the cheek and upper limb melanin.The content was the lowest(P<0.05);the melanin content of female forehead skin was the highest(P<0.05).In the 1-2 age group,males had the highest melanin content in the forehead,followed by the upper limbs and the lowest in the abdomen(P<0.05).Women also had the highest melanin content in the forehead(P<0.05).The melanin content in the forehead and upper limbs of the males in the 1-2 age group was significantly higher than that in the 0-1 age group.The melanin content in the upper limbs of the 1-2 age group was higher than that in the 0-1age group(P<0.05).In the 0-1 age group,men had the highest hemoglobin content in the forehead and the highest hemoglobin content in the abdomen of women(P<0.05).In the 1-2 age group,men and women also had the lowest hemoglobin content in the lower extremities(P<0.05)..The hemoglobin content of the forehead and cheek skin of women in the 1-2 age group was higher than that of the 0-1 age group(P<0.05).Conclusion Infant skin has unique skin physiology,with significant differences between age,gender and different anatomical locations.
