The Candela GentleLASE is a high energy, long-pulse laser that can treat a variety of conditions. The laser creates a beam of high-intensity light that penetrates deep into skin tissue where it delivers a controlled amount of therapeutic heat. Candela's patented Dynamic Cooling Devise (DCD) technology protects the upper layers of your skin with a cooling burst of cryogen. Together, the long-pulse laser and DCD cooling offer optimal treatment with minimal side effects.
