Over the last 20-30 years in the field of medicine and surgery has been introduced the use of laser therapy technology (ie, light amplification by stimulated emission of radiation).
The laser technology, applied in both surgical and medical dermatology and vascular surgery, is known and used successfully for several years.
There are different types of lasers that differ depending on the wavelength emitted and therefore have different uses, in fact, each type of laser therapy is absorbed by a particular pigment, and therefore has a different “target”.
For example, in cosmetic surgery can be used successfully with various types of lasers to correct aesthetic defects congenital (from birth) or acquired.

The laser therapy selectively targets, let’s have that affects each type of laser:
The fabrics usually have a variable content of pigments such as hemoglobin chromophores and water different from each other, and then the doctor will use aesthetic or cosmetic surgeon for treatment, the laser that emits electromagnetic radiation that is absorbed more by the particular target tissue.

The absorption of the laser beam depends on the wavelength and the particular characteristics of the target tissue, which is affected in a selective way.
The therapeutic effect depends not only on selective absorption by the target tissue, although the intensity of electromagnetic radiation and the duration of the laser treatments.
It ‘so easy to see that there is a laser that is valid for every kind of disease or defect in appearance, but the type of laser should be used more appropriately and effectively.
Hence the importance of always relying on a physician or surgeon experienced, qualified and trained, it can ensure the necessary safety of laser treatment.
