Laser treatments involve, in the optimum situation, the controlled removal of layers of sun, or scar damaged skin as well as the removal of atttoos..  It allows the body to replace these cells with more youthful skin.  Performed correctly, this procedure has several advantages over treatments such as mechanical dermabrasion, where it is more difficult to achieve a uniform effect on the skin surface. Mechanical dermabrasion is more aggressive than microdermabrasion and uses small electric skin abraders). It is also much more controlled than the deeper chemical peels such as the higher strength TCA peels.

Unfortunately, however, the media hype and encouragement from the laser companies initially attracted many specialists and non-specialists who lacked suitable training.  In some cases they have been 'trained' at weekend courses and often their treatment has led to scarring and skin discoloration.  It is essential, therefore, to ensure that this form of treatment is carried out by someone who has been fully and appropriately trained in its use.  Ask to see certificates of training in the use of these lasers, and also to speak to and see photographs of previously treated patients.

History of lasers:
In the 1980's doctors in southern California used a carbon dioxide laser to remove precancerous skin patches on the upper lip.  Following the removal, during the course of healing, they noted that lines that the patient had on the upper lip were also considerably improved.  This led to the first report on laser skin resurfacing.

About four years later the UltraPulse carbon dioxide laser was developed.   This laser had special characteristics in that it allowed the delivery of energy in very small fractions of a microsecond.  In practical terms this allowed an almost layer-by-layer removal of skin.  Also, the density or thickness of skin removal could be varied using computer-controlled delivery of the laser.

Other lasers developed subsequently include the YAG lasers, which were even more precise and very versatile but did not seal the blood vessels in the way that the UltraPulse CO2 did and therefore tended to cause considerable bleeding.  There is now an erbium YAG laser that can 'copy' the benefits of the UltraPulse carbon-dioxide laser.
It has become apparent that by doing more superficial skin resurfacing it is possible to achieve a much more rapid healing process than is possible with deeper, more aggressive laser treatment.

As a result of this, patients are often able to return to work eight or nine days after the procedure.  This technique is much less severe than the old one, following which it could frequently take weeks, if not months, for the patient's skin to return to normal.  It also allows for follow-up treatment to take place 12 months or so later to attain further improvement.
