Freckles are brought about as a result of exposure to the sun, meaning a baby may develop them as soon as he or she is exposed to the sun, according to the Women's and Children's Health Network. Freckles are small dark marks that appear on the skin and may vary in severity depending on the type of skin the baby has.
When melanocytes are grouped together instead of being evenly spread under the skin and exposed to the sun, they produce larger quantities of melanin, which is why dark spots appear on the skin. Melanocytes are the cells responsible for producing melanin, which is a pigment that makes the skin appear darker
Freckles can only develop when a baby has been exposed to sunlight and may be red, tan, yellow, light brown or dark brown in color. Babies who have soft skin are more likely to develop these marks. Freckles usually develop on the face, shoulders and arms but may also affect other parts of the body.
To prevent freckles, babies should not be exposed to direct sunlight. Wearing hats and sleeved tops is recommended. Using sunscreen can also go a long way in preventing these marks. Freckles do not have any harmful effects on human health but may be an indicator of vulnerability to skin conditions like cancer.
