Aesthetic Laser Treatment Allows For Simpler and Faster Cosmetic Procedures

Uncategorized

When you are going in for a cosmetic procedure, you will know that the latest surgical procedures make a lot of use of lasers for treating different skin conditions.

Laser stands for light amplification by stimulated emission of radiation, and in this technology, one color of light in a single wavelength is given high energy, so that this light can be accurately focused so that the light is transmitted to a very small area. Lasers can be ablative and are lasers that can vaporize the upper layers of the skin that has been damaged. Lasers that are non-ablative work deeper in the skin and do not affect the top layers in any way.

In aesthetic laser treatment, the process used is called selective photothermolysis. The frequency of the light used produces heat in the specific area that is targeted and destroys it. Lasers come in many types, and the type used for any cosmetic procedure will depend on the type of skin condition that needs to be corrected.

Treatments using lasers can be of great help in removing unwanted hair. Care has to be taken to use lasers that suitable for the particular skin type. Intense pulse light is also used for hair removal instead of lasers, as this technique can treat larger areas at the same time. Laser resurfacing is used for the resurfacing of the skin and its rejuvenation. It is very effective in removing scars from acne, reducing facial wrinkles and other blemishes of the skin. Scanners are often used in this form of cosmetic procedure to ensure that only one layer of skin is being removed at a time. For treating skin conditions a wide range of wavelengths is used for the lasers, as this permits shallow to deep penetration as required.

One aspect of aesthetic laser treatment allows people to get rid of tattoos, a procedure that was earlier difficult and painful, and at times impossible. Here the wavelengths used will depend on the color of the tattoo ink that needs to be removed. The heat generated by the lasers used in this removal procedure breaks down the ink from the tattoo. These smaller particles of ink then get absorbed by the immune system of the body. Vascular lesions that form on the body include blood vessels, and their removal requires lasers of lower frequencies. Pigmented lesions can also be removed through the use of lasers.

It is important that where the lasers used are the invasive kinds, the energy that is being used is constantly monitored so that there is a fair degree of control over the power used and energy being created by the laser. Non-invasive layers do not need such monitoring, but it is highly important that the devices are properly calibrated by qualified technicians before they are used for any cosmetic procedure.

The field of laser and light treatment for cosmetic procedures is vast and newer techniques and instruments are constantly being developed. This includes not only lasers but also intense pulse light, infra-red energy, and radiofrequency, among others.
