Reported as a paper on confirmation of skin conditions and field surveys by dermatologists for children aged 4 to 10 years old from infancy to school age

Natural Science Co., Ltd. (Headquarters: Chuo-ku, Tokyo, President: Reiko Komatsu), a skin care manufacturer for sensitive skin, has skin care products for children aged 4 to 10 from infancy to school age by dermatologists. We checked the status and conducted a fact-finding survey using equipment measurements.
The results of this research were presented at the 44th Annual Meeting of the Japanese Society of Pediatric Dermatology held in January 2021 and published in the November issue of Allergy Clinical Practice published on October 31, 2022. rice field.
So far, we have investigated the skin of newborns and infants and verified the effects of skin care with the cooperation of
dermatologists, pediatricians, and obstetricians and gynecologists. In recent years, the need to maintain the moisturizing function of the skin of newborns and infants is spreading. However, from infancy to school age, children become active outdoors and are often exposed to external stimuli.
Therefore, this time, we conducted a fact-finding survey by
dermatologists to check the skin condition of children aged 4 to 10 years old from infancy to school age and to measure the skin conditions using equipment.
As a result, dryness and desquamation were observed from the doctor’s skin findings, and the moisture content of the stratum corneum and the amount of sebum were low, indicating that the moisturizing function was low. In addition, the thickness and density of the dermis in children aged 4 to 10 tended to increase, indicating that they were still in the growth stage.
Research background
In recent years, the skin physiology of newborns and infants has been reported, and it has become clear that the application of moisturizers early after birth reduces the onset of allergies such as atopic dermatitis. For newborns and infants, the importance of maintaining skin moisturizing function is spreading.
Compared to the neonatal period and infancy period, children from infancy to school age have a wider range of activities and more outdoor activities, so they are more susceptible to external stimuli, and it is said that eczema and dermatitis are more likely to occur. Recent reports indicate that children who develop atopic dermatitis from infancy to school age may continue to have symptoms, and caution is required. However, because there are few survey reports on the skin of children from infancy to school age, we investigated the skin conditions of healthy children aged 4 to 10 years.
In this study, 35 healthy children aged 4 to 10 years (17 boys and 18 girls) were examined by dermatologists, and their skin findings, stratum corneum water content, sebum content, skin thickness, etc. I took measurements.
Based on the background of the subjects, the subjects were divided into a preschool group aged 4 to 6 and a group aged 7 to 10, and analyzed.
1) Skin findings (Figure 1)
In terms of skin findings, dryness and desquamation were observed all over the body in both the infant group and the school-aged group. [Image 1

Figure 1_Skin findings (by observation item)
2) stratum corneum moisture content, sebum content (Fig. 2)
It was found that the stratum corneum moisture content was low in both the infant group and school-age group. The amount of sebum in the school-aged group tended to be higher only in the forehead area compared to the infant group, but it was found that the school-aged group was low in other areas.

3) Skin thickness (Figure 3)
From the measurement of the skin thickness of the upper extremities, no age-dependent increase in epidermal thickness was observed between 4 and 10 years old, but the dermal thickness and skin density tended to increase with age in the forehead, abdomen, upper extremities, and lower extremities. It turns out that the skin is in the growth stage. [Image 3

Skin findings and device measurements suggest that skin conditions in childhood and school age have low moisture content in the stratum corneum, low sebum content, and low barrier function, leading to changes in skin symptoms such as dryness and desquamation. it was done. Compared to the neonatal period and infancy, infants and school children have a wider range of activities. It is thought that it is necessary to enhance the skin barrier function even in school children. Improving the skin barrier function may prevent not only atopic dermatitis but also the development of food allergies due to transcutaneous sensitization and the subsequent allergic march. It is thought that skin care guidance such as care is important.
In the future, since infants and school children are affected by various factors such as ultraviolet rays and dryness, Natural Science will conduct further research on skin conditions and propose appropriate skin care methods that can prevent atopic dermatitis and allergies. I would like to come.
