The Gentle Max Pro Laser can treat skin types I-IV and can remove hair from virtually anywhere on the body, including back, stomach, underarms and bikini area. Hair types vary greatly between different people and different areas of the body. For example, finer hair is usually seen on the body compared to the legs. Thicker and courser hair requires more treatments to remove it. Although you will see significant hair reduction after your first treatment, most clients need between 4-8 treatments to see significant hair reduction and will require maintenance treatments every 1-2 years.
