A laser increases the effectiveness of the treatment of hypertrophic and keloid scars by cutting off blood supplies that contribute to scarring. Therefore, the process of uncontrolled scarring ends. A laser may be sufficient in treating keloid scarring that is flatter and thinner. But vascular lasers may be more suitable for treating scarring that is thicker and deeper.
This is followed by steroid injection. Because of the laser and the steroid injection, the fuelling blood supply is halted. Because of the swelling of the scar tissue, this combination of treatments will make the steroid injections uniform and more effective. Injecting steroid hormones and using a vascular laser together enables keloid scars to be resolved much faster. Therefore, fewer treatment sessions are necessary because the overall result is superior.
