What is the purpose of using a cooling device during laser treatment?

The purpose of using a cooling device during laser treatment is primarily to protect the skin from thermal injury. Laser treatments often involve the application of high-intensity light, which can generate significant heat that, if not managed properly, could lead to skin damage or burns. By integrating a cooling mechanism, such as cryogen sprays, contact cooling pads, or air cooling, the skin's surface is kept at a lower temperature even as the laser energy penetrates to deeper tissues. This protective approach minimizes discomfort for the patient and helps to mitigate the risk of adverse effects, allowing for a safer and more effective procedure.

In a medical or aesthetic setting, maintaining skin integrity while delivering effective laser energy is crucial for optimizing patient outcomes. Reducing skin temperature helps enhance patient comfort and ensures that the treatment can be effective without compromising skin safety.
