The laser treatment itself can range anywhere from 30 minutes to an hour, depending on the treatment area(s). For example, a patient receiving HALO to the Face, Neck, and Décolleté would be closer to an hour, while only a treatment to the Face would be closer to 30 minutes. Regardless, we still advise patients to arrive an hour before treatment to place a numbing agent onto the areas of treatment. Or, if the patient prefers, we can call in the numbing agent to their local pharmacy and they can arrive already numb.
