(the coloured pigment).
• The laser light must be preferentially absorbed by the tattoo pigment than the surrounding tissue
i.e. Photo (light) is converted to Thermo (heat) which lysis (destroys) the Chromophobe
The laser light is sensitive to colour i.e. The laser light is attracted by the colour of the pigment. The Nd:YAG laser has a wavelength of 1064 mm, which is effective for the removal of black and blue pigments. It can be 'Q-Switched' to a wavelength of 532 mm for the removal of red, green, yellow and orange in pigments. The pigment is destroyed when it absorbs the heat of the laser, causing the pigment to 'explode', and the smaller particles are removed by the scavenger cells in the body.
The requirements for effective tattoo removal • The laser light must penetrate the skin to reach the pigment
• Short cooling time of the laser light used ensures that energy is absorbed by the pigment without heat dissipation, which can damage surrounding tissue All of this will remove the pigment without damaging or scarring skin and also avoid 'ghosting', where pigment is removed but the tattoo outline is still seen. The Q-Switched Nd:YAG laser is the only method that meets all the above requirements for successful tattoo removal.

Care of the treated area There will be a fine ooze in the treated area, and hence thiss will need a non-stick dressing. Usually, Cling Wrap is very usefull ays) for this temporary (3 to 4 days) inconvenience. A crust, which may form, will fall off after a few days. Complications Scarring is not a problem with the Nd:YAG laser. There is also no 'ghosting', the persistence of a lighter coloured outline of the tattoo. Hyperpigmentation is always a risk in darker skinned people and may need additional treatment to reduce this.
The Nd:YAG laser in the treatment of ARGYRIA ARGYRIA, the deposition of ingested silver in the skin is becoming more of a problem with the increased use of silver in serious gut infections. This causes severe black pigmentation of skin and is a most distressing side effect of silver ingestion. The Nd:YAG laser is very effective in the treatment of ARGYRIA, with a single treatment required for removal of the pigment and restoration of skin colour.
