To begin, the laser emits a wavelength that penetrates through the skin and targets the overactive Sebaceous Glands (Oil Glands). When the sebaceous glands are heated, it causes a mild thermal injury that changes the activity of the glands. Simply stated, the glands no longer produce the same amount of oil, which is the main cause for breakouts. Also during treatment the nd:YAG Laser kills acne causing bacteria under the skin. This gives our clients better lasting results.
