Freckles, age spots, café-au-lait spots, and sunspots are key examples of benign pigmented lesions that can be removed with Q-switched laser, often in a single treatment. Pigmented lesion removal is a popular cosmetic procedure that can turn back the effects of time and sun exposure to restore unblemished skin.
During treatment, Q-switched laser pulses are applied directly to the complete area of the lesion. The skin cells containing excess melanin absorb the intense laser energy, heat up, and degenerate. Meanwhile, the surrounding skin tissue is unharmed. After treatment, as the area heals, the immune system flushes away the dead skin cells and reveals lighter, unblemished skin.
Procedure time depends on the size of the lesion treated. An age spot can take a single second to treat, while a large birthmark or nevus can take up to a few minutes. Patients may experience slight discomfort during the procedure, but the side effects are minimal.
Most pigmented lesions can achieve complete removal after an adequate number of sessions. Some small lesions (such as freckles or age spots) may take a single treatment to remove – others can take six or more treatments, depending on a variety of factors.No recovery time is necessary, but treatments are typically scheduled six weeks apart to allow time for the patient’s skin to heal.
