We had a baby boy 21 days.... He looked very fair on the day he was born... but since a week back his skin becoming dark... why? what should we do to get fairer skin tone?

A. At birth, your child's skin is likely to be a shade or two lighter than her eventual skin color. The skin will darken and reach its natural color in the first two to three weeks. This is a great time to start thinking about a regular skin care routine.
