After a enlighten III laser session, there can be a healing time. The skin that had the laser pulses penetrated into it may turn red, and may also blister. For this reason, we ask that you use Polysporin to aid the healing. After your treatment, you  may cover the area with gauze if need be, though we do ask you to leave the treatment area open during healing if possible. However, when engaging in any activity that can cause infection (such as working in a dusty place, or spending time outdoors), we do ask that the area be covered. Of course, as with any cut or scrape, it is advisable to avoid swimming and sun exposure, or activities that can irritate the skin. You should be able to return to work, or go out in public, if you are comfortable. Generally speaking, it can take a few days for the skin irritation to subside.
