Babies who grow up with dark skin usually don’t turn white on their own. Skin color is determined from birth and doesn’t usually change slowly over time. A large part of the reason for the color of the skin is because of the genes of the parents, if one of the child’s parents has black skin, then the child has a 50/50 chance that he or she may be genetically predisposed to it. The skin cannot become white on its own, but it can be improved, possibly to some extent, through acquired sun protection, diet, and skincare. If the child accepts the color of the skin itself, then as a parent you don’t need to worry too much, the child’s physical health is more important. Pay attention to your child’s nutritional balance during the growing process, and seek medical advice if necessary.
