A laser pulse occurs for a fraction of a second, treating numerous hair follicle at the same time. Each laser pulse lasts long enough to heat up the hair and significantly destroy the follicle’s ability to re-grow. A special contact-cooling handpiece protects and cools the upper layer of the skin before, during, and after each laser pulse while directing the laser energy to the hair root, allowing treatment to even the most sensitive skin. This method is ideal for darker hair, lighter skin, and is able to treat even the largest areas of the body quickly and effectively. Depending on the area of the body, treatments are typically scheduled 6-12 weeks apart and can take 15-60 minutes per session.
