Working Principle: 980nm diode laser is one latest, most powerful, and most reliable technology which is a safe and effective treatment for vascular removal, nail fungus removal, physiotherapy, skin rejuvenation, and the functions of the Ice compress hammer. The laser penetrates deep into the blood vessels. According to the principle of selective photo heat, the haemoglobin in red blood cells in blood vessels is the main target colour group. The laser energy is absorbed and the heat energy is transferred to the surrounding endothelial cells.
