In general, fractional laser treatment may cause a certain degree of pain during the procedure, although the level of discomfort varies among individuals and is usually tolerable. Fractional laser therapy is a skin rejuvenation technique widely used in the field of dermatology and cosmetic treatments, such as for acne scars, wrinkles, and hyperpigmentation. During treatment, fractional lasers create microscopic zones of thermal damage, which stimulate the skin's natural healing mechanisms and promote the production of new collagen, thereby improving skin texture and appearance.

Because individuals vary in their tolerance to pain, the perceived level of discomfort may differ. Some people may only experience mild discomfort, while others may feel more significant pain. Pain perception can also vary depending on the treatment area. Generally, pain sensations in sensitive areas such as the face may be more noticeable compared to other parts of the body.

Prior to treatment, physicians typically apply a topical anesthetic to the treatment area to reduce discomfort during the procedure. After treatment, patients may use an ice pack or cold compress gently on the treated area to help alleviate swelling and pain. If a patient is particularly sensitive to pain or concerned about discomfort during treatment, it is recommended to communicate fully with the physician beforehand to develop a personalized treatment plan that minimizes pain.
