The causes and care measures of neonatal acne are as follows: 1. Excessive androgen in the mother: neonatal acne may be related to the fact that when the baby is still in the mother’s womb, the mother’s body is too high in androgens due to certain reasons, androgens enter the baby’s body through the placenta. After the baby is born, too much androgen in the body prompts the sebaceous glands to secrete exuberantly, forming acne; 2, Malassezia infection: it is related to the baby’s skin infection with Malassezia. Second, care: 1, face care: acne babies with special baby shower gel, or temperature of about 38-40 ℃ warm water to wash the face every day, with a soft towel gently absorb the moisture, to keep the facial skin clean, dry; 2, prohibit powder cosmetics: do not give the baby with grease or powder skin care products, so as not to clog the pores, so that the acne symptoms aggravated; 3, disinfection: the baby’s face basin, towels and other household items should be cleaned and sterilized separately, and parents should not squeeze the acne area with their hands.
