Treatment of Pigment Disorders with QS-Nd Yag Laser

The QS-Nd Yag laser is used to remove deep-seated melanocytes, Ota nevus, pigment disorders, and tattoos, as the cells which cause these forms of hyperpigmentation are deeper in the dermis.


How Does QS-Nd Yag Laser Work?

The system produces a high intensity laser beam in very short pulses. The skin pigment absorbs light energy, which destroys melanin naturally without affecting surrounding tissue.


What Can Be Treated?

  • Deep-seated melanocytes or dark patches: Deep-seated melanocytes are pigmented lesions involving blue, grey, or brown-grey macules.
  • Tattoos: Tattoos can be removed with short pulses of energy, breaking up the pigment colors of the tattoo – and further removed naturally by the body’s immune system.


What Parts of the Body Can Be Treated?

All areas of the body can be treated with the QS-Nd Yag laser.


Is QS-Nd Yag Laser Treatment Safe?

The QS-Nd Yag laser has been developed to produce effective treatment with no side effects. The laser device is considered very safe and has been approved by the U.S. Food and Drug Administration (USFDA) and the equivalent agencies throughout Europe and Asia (including Thailand). The USFDA has specifically approved the QS-Nd Yag laser as an effective treatment for pigment disorders and tattoo removal.


Are There Any Special Precautions I Need to Take Before and After Treatment?

Before Treatment : Avoid sun exposure or sunbathing for at least 14 days before treatment.

After Treatment: Wear an SPF 30+ sunscreen to reduce the risks from sun exposure.


How Many Treatments Are Required?

The required number of treatments is specific to each patient, since there are a few different types of skin pigment disorders occurring in varying degrees. Concerning tattoos, the treatment for each individual patient depends on the opinion of the doctor, who will choose the right treatment schedule for each case based on the previous treatment results and responses.


What to Expect During and After Treatment?

During Treatment : Patients may feel some warmth or slight discomfort during treatment.

After Treatment : Patients may experience some burning sensation on the treated areas. However, the symptoms will dissipate within 4-6 hours. The treatment may leave scars and cause some bleeding. The lesions will initially become darker, but will soon dissipate.
