Fetal fat in newborns can be wiped away using a damp tissue, but it usually comes off on its own and can be left untreated.
Fetal fat is a layer of white greasy fat on the skin of newborns when they are first born, and it tends to accumulate in the neck, groin, perineum, armpits, and other skin folds, so if there is a lot of fetal fat, it can be cleaned.
Usually, you can use baby wipes to wipe it off, but do not repeatedly wipe it off with force so as not to cause damage to the skin, in addition, you can also wash off the fetal fat when taking a bath.
Fetal fat can help moisturize the skin to a certain extent, so if even if the fetal fat is relatively small, there is no need to deal with it, usually in a few days after the birth of a newborn baby fetal fat will fall off from the skin on its own, so parents do not need to worry too much.
