With shallow treatments, the laser peel is usually well tolerated with a topical anesthetic. For deeper treatments, both topical and local anesthetic medications are required, and many patients also opt for sedation anesthesia. Just before treatment, your skin will be cleansed, and your eyes will be covered and protected. A laser handpiece will then be positioned over the skin and held in place while a computer-guided scanner moves the laser beam. Depending on the treatment area(s), this procedure will be completed within just a few minutes for smaller zones, and up to 30 minutes for the full face.
