Cooling Facility Enhances Laser Performances
Some latest laser devices come with inherent cooling systems. A method of cooling simultaneously when applied with high wavelengths of laser beams ensures safety of the skin epidermis. Greater intensity of light energy is occasionally required to treat patients with special considerations and light hair color; this increases the risk of damage being caused to the skin surface. But using one of the cooling techniques for prevention of skin burn highly reduces chances for any major side effects and pain.
Cooling techniques popularly used by medical practitioners include use of a clear gel that is at chilled temperatures. Another type of contact cooling is also possible where reduction in temperature is brought through cool circulating water. Using a cryogen cooling spray just before and after inducing laser pulses facilitate skin cooling while the hair follicles are destroyed by high-density lasers. Several studies support cooling methods as a safe precautionary measure to combat damage of epidermal cells while using maximum energy densities during treatment sessions.
