Hi. Greetings. Firstly please understand that fairer complexion doesn't mean more beautiful! You must rather ask about healthy skin than fairer skin. For decades companies like fair and lovely have caused people to have weird mind sets and expectations. Let your sun grow to have his normal complexion given to him by God and nature. Just parents being fair may not be the only criteria for "fair complexioned children" . let him use a sunscreen when he's out doors and a good diet rich in fruits and vegetables will help his skin remain healthy and glowing. Hope this helps. Dr Govind S Mittal, Bangalore.
