Incorporating the latest technology, the Gentle YAG Laser provides safe and effective treatment. Laser light safely penetrates into skin so that the tissue can absorb the energy without the need to remove the top layer of the skin. Improvements to the skin can be seen after each treatment. In most cases, there is no need to use anesthetic or skin numbing cream before treatment. However, there is a small chance of redness, bruising or scarring following treatment.
