    Technology at the Service of Beauty

    Among all the non-surgical treatments known to achieve a youthful appearance, one has already reached the first place in effectiveness: the laser. Today, the method is considered the main means of facial rejuvenation available due to its impressive power to erase wrinkles, blemishes, expression marks and acne scars, in addition to returning to the face much of the youthfulness and tone that are lost with passing of the years.

    For its results, it works as a milestone in Humanity’s ancient search for beauty. With this technology, it is possible to obtain results very close to those achieved with plastic surgery, through simple applications in medical offices.

    The CO2 laser, for example, reduces facial wrinkles with at least 45% consistent improvement over the entire face area. Depending on the triggered wavelength, the energy of the various lasers can be directed to targets such as hemoglobin (red blood cell) or melanin, the pigment that gives color to the skin. For this reason, it is able to promote more effects, in addition to eliminating wrinkles, and achieves objectives such as: mitigating spots and superficial blood vessels.

    Fractional lasers

    Undoubtedly, one of the greatest advances in the history of the laser was the creation of so-called fractional lasers. The first was developed at Harvard University, in the USA. Its main feature is to emit rays that enter the skin alternately. The bundles penetrate microscopic points, thinner than a hair. This type of technique allows the rays to act, but leave some healthy cells in the treated area intact.

    In this way, the laser is less aggressive. The person can make the application and resume activities the next day. Before, because of the intensity of the effect caused by powerful lasers, such as CO2, which was quite aggressive and promoted an intense peeling (to the point of removing the surface of the skin), the patient only resumed his normal routine, at least, one month after the procedure.

    Several studies have concluded that the laser is really capable of promoting, on the skin, effects intense enough to contain the damage of time. This is done by activating the production of collagen, a protein that provides support to the skin. When collagen “lacks” (or is weakened), which happens with aging, wrinkles and sagging appear.

    Other applications

    In addition to lasers, there is another radiation – called “intense pulsed light” – that can be used for the same purposes. It has variable wavelengths and is therefore less selective than the laser. While the latter hits a single target, be it a spot or a vase, the intense pulsed light falls on several. This feature makes it an attractive feature to prevent wrinkles and improve skin tone in general. As there are many options, what brings more results is the combination of treatments.

    Today, it is known that the laser also gives good results in the reduction of hair, varicose veins, cellulite, stretch marks and hair loss, since it can increase the cellular activity at the root of the wires. In addition, ways of improving the results of treatments against scars and tattoos are being studied, which still fluctuate a lot. In the case of scars, the ideal is that the treatment is started as soon as possible, so that the rays are able to remove the reddish color that can be attached to the marks. And, for tattoos, there is still no efficient technology to erase all colors. The most difficult to disappear are yellow and red.

    One of the new discoveries about the effects of the laser is a device to eliminate body fat. Against it and cellulite there are already options that combine infrared lights with radiofrequency and a device that does liposuction with the help of a laser after inserting a cannula under the skin. But cryolipolysis has proven to be an effective method. The device emits waves with a length that destroys fat cells, called adipocytes.
