It can help: Co2 or erbium laser are two commonly used laser therapies for mild to moderate acne or other scarring of the face. You could seek an evaluation with a plastic surgeon, facial plastic surgeon(ent trained) or other properly trained cosmetic specialist to evaluate you for this. This can minimize the problem and sometimes several treatments spread out over time can be very effective.
