The pigmentation of a baby's skin in the womb, which determines skin darkness, is influenced by genetic inheritance from the parents. Melanin, the pigment that colors skin, begins to be produced as the baby develops. Factors such as genetic makeup and ethnic background play significant roles. Additionally, exposure to certain substances or nutrients during pregnancy does not significantly change the baby’s innate skin color. Understanding that skin tone is a hereditary trait helps in anticipating the range of possible skin colors for your baby.
