In full-term newborns, the skin has a structure and barrier function that allows it to adapt to extrauterine life. 1,2 However, diaper dermatitis may develop on the buttocks, including the perianal area, during the process of adaptation to the environment after birth. At 4 days after birth, skin rashes, characterized by erythema and papules, have been observed on the buttocks and perianal area, 3 and skin care of the diapering area is important from early in life. One of the prevention or treatment measures for diaper dermatitis is the use of skin protectants, 4 which are expected to form a protective film on the skin, 5 reduce transepidermal water loss (TEWL) by occlusion, and maintain the hydration of the stratum corneum. It has been reported that there was no significant difference in the incidence of diaper dermatitis in preterm infants treated with petroleum jelly 6 and that TEWL was significantly lower in infants aged 9-12 months who were treated with commercial diaper cream. 7 Human breast milk 8 and cream-to-powder products 9 have also been investigated, but there are limited studies on the use of skin protectants around the diaper area in newborns. 10 Moisturizers are commonly used in the skin care of newborns and have been shown to be effective in maintaining the general skin
