One of the great benefits of the CO2 laser is the versatility it provides during treatment.For example, your TWACHA doctor can use a variety of settings to disperse the laser beam bursts across the treatment area. This can be very helpful for reducing down time after treatment, so that you can recover faster. Additionally, the CO2 laser can be calibrated to different levels of energy bursts, which allows your provider to fine-tune the treatment to your specific needs. If we choose the higher settings,for eg. in case of deep scars, there will be more skin ablation and downtime is roughly 5- 7 days. You will have redness and mild swelling of the skin for 1-2 days. You must strictly avoid sun exposure for 5 days. But if the settings are lower, eg. for skin roughness, or enlarged pores, then there is mild redness for a few hours. There is no downtime after this, but you should still apply sunscreen every 3 hours.
