Flat dark moles can be electrofulgurated or lasered easily to lighten them up but may need a few treatments. Sincerely,
It is difficult to evaluate your moles fully from your photo. If any of the moles are raised, they could be shaved off. If any of them are flat, they would need to be excised. It is not possible to leave no scar after either procedure, but in the ideal setting, any scar would be less noticeable than the mole.
