What Mommy should know: the average surface area of the baby’s skin is 2500 square centimeters, the average weight is 5kg, the ratio of the two is 500; the average surface area of the skin is 18000 square centimeters, the average weight is 65kg, the ratio of the two is 270; therefore, the proportion of the baby’s skin area and weight is large. In addition, the baby’s thin skin can promote the absorption of washing and care products. In this way, for people who are exposed to the same amount of irritants and poisons, they not only absorb more than adults, but also have a much stronger reaction to allergic substances or poisons. Therefore, skin care products suitable for adults may not be suitable for babies. Because adults will not have any discomfort due to less absorption, while babies may show very serious skin damage and systemic symptoms. So, use your own soap to bathe your baby. But a few days later, the baby suddenly had a fever, and a lot of red rashes appeared on her body. Why is the baby like this? Mummy’s correct care method: Method 1: the lotion should have higher safety. The lotion with “special formula for infants” must pass the strict medical test to prove that the ingredients are pure ingredients for infants, which have mild and harmless effect on the baby’s skin; And completely in line with the baby’s body surface skin area is relatively large physiological characteristics, will not cause skin allergic reactions, toxic reactions and systemic reactions, so it is the first choice for mummy. Method 2: will not let the baby absorb too much harmful substances, because the baby’s skin is often polluted by urine, so some lotion contains bactericidal ingredients. However, the mother must give the baby the use of special care products for infants and young children. That is, the concentration is appropriate and effective, preservatives and colorants in line with the physiological characteristics of the baby’s skin, no or less spices. In this way, the baby will avoid absorbing too many substances harmful to health.
