Hello I'm Dr Chip
Have you ever had a keloid form from a cut or similar injury?
No, lightening the skin beforehand wouldn't prevent a keloid from forming. The problem with people who do form keloids in is the skin itself and not specific to the darkness of their skin.
But it doesn't sound like you have that kind of skin so there should be no problem with your surgery
Please let me know if you need any more information
