ND-YAG Laser

The ND YAG Laser emits high energy instantaneously. It can break the pigment of pathological tissues. The high energy produced by ND YAG laser make the particular wavelength to penetrate into the epidermis. It is only 6nms for the high energy to pass into the pathological pigment tissues. Then pigments expand in top speed and explode. The pigments will be faded and disappeared with the daily metabolism.

In Q-switched mode, Nd:YAG produces 2 wavelengths, one in the infrared range (1064 nm) and the second beam of 532 nm wavelength which is useful for superficial skin lesions. Q-switching refers to the technique of making the laser produce a high-intensity beam in very short pulses。The 1064nm wavelength will shatters and removes the black and blue pigments while the 532nm wavelength will shatters and removes red, pink, purple and brown pigments of the tattoo or other pigmentations without damaging the normal tissue.

The Special Wavelength of 532/ 1064 yag laser can penetrate skin of human body according to the theory and practice of “Selective Laser Decomposing”, the instrument uses the laser-wave to break Chromatophore into pieces which can be naturally absorbed by the body. So that it achieves the purpose of the-freckling.  

The colour of the tattoo and the depth of the pigment influence the duration and the outcome of the laser treatment.

It is important that the correct diagnosis has been made by the clinician prior to treatment, particularly when pigmented lesions are targeted, to avoid mistreatment of skin cancer such as melanoma.

The patient must wear eye protection (an opaque covering or goggles) throughout the treatment session.

Treatment consists of placing a handpiece against the surface of the skin and activating the laser. Many patients describe each pulse feeling like the snapping of a rubber band against the skin.

A topical anaesthetic may be applied to the area but is not usually necessary.

Immediately following treatment, an ice pack may be applied to soothe the treated area.

Care should be taken in the first few days following treatment to avoid scrubbing the area, and/or use of abrasive skin cleansers.

During the course of treatment, patients should protect the area from sun exposure to reduce the risk of post inflammatory pigmentation.

Are there any side effects from ND YAG laser treatment?
Side effects from Nd:YAG laser treatment are usually minor and may include:

Pain during treatment (reduced by contact cooling and if necessary, topical anaesthetic)
Redness, swelling and itching immediately after the procedure that may last a few days after treatment
Rarely, skin pigment may absorb too much light energy and blistering can occur (this settles by itself)
Changes in skin pigmentation. Sometimes the pigment cells (melanocytes) can be damaged, leaving darker (hyperpigmentation) or paler (hypopigmentation) patches of skin. Generally, cosmetic lasers will work better on people with lighter rather than darker skin tones
Bruising affects up to 10% of patients. It usually fades on its own
