What is the function of a cryogen spray in laser treatments?

The function of a cryogen spray in laser treatments is primarily to cool the skin and minimize discomfort. When lasers are used for various dermatological procedures, such as hair removal or tattoo removal, they generate heat that can cause discomfort or even damage to the skin. The cryogen spray acts as a cooling agent, applying a brief burst of cold to the treated area. This not only reduces the temperature of the skin but also helps to alleviate pain during the procedure, allowing for a more comfortable experience for the patient.

By cooling the skin, the cryogen spray also protects the epidermis, which can be susceptible to thermal injury from the high-energy laser light. This cooling mechanism is beneficial in helping the skin tolerate the laser treatment more effectively, leading to improved patient satisfaction and potentially better clinical outcomes.
