In the arsenal of a plastic surgeon today there are several ways to eliminate wrinkles, skin irregularities, remove scars and scars and pigmentation. These are all kinds of peelings with various chemicals, and microdermabrasion with special grinding brushes, and a laser. The laser has occupied a strong niche in many areas of medicine, including plastic surgery and cosmetology. Laser skin resurfacing has gained well-deserved popularity among other methods of wrinkle removal and is considered one of the most effective procedures. It is used both to eliminate wrinkles and scars after acne, small wrinkles, crow’s feet, etc.
What is laser skin resurfacing
Laser skin resurfacing is based on the effect of laser energy (light polarized in a certain way) on the surface layers of the skin. The laser, as it were, burns out the surface layer of the skin, thereby leveling its surface. Three types of laser radiation are commonly used for laser resurfacing – an erbium laser, a carbon dioxide (CO2) laser, and a low-intensity laser radiation. The laser, penetrating into the superficial layers of the dermis, leads to an increase in temperature and the evaporation of its water from the cells, as a result, the old layers of the skin are “burned out”, and the renewed skin regenerates in this place.
The effect of laser skin resurfacing is not only the removal of old dead skin layers, but is also accompanied by smoothing of fine wrinkles and smoothing of deep wrinkles in the area of resurfacing. The laser also effectively smooths out acne scars and other small scars on the skin, which become almost indistinguishable after resurfacing.
The carbon dioxide laser, in addition to smoothing wrinkles and smoothing scars, also has a tonic effect on the skin, improves its color and appearance and improves its texture. A feature of a low-intensity laser is that it is able to stimulate collagen synthesis in the skin, which favorably affects the properties of the skin and rejuvenates it.
Disadvantages of laser resurfacing
Among the disadvantages of laser resurfacing is the fact that it is not always effective for deeper wrinkles. In some cases, several sessions of laser skin resurfacing may be required. Among other things, laser resurfacing, although not an invasive procedure, requires a certain recovery period after its implementation.
How does the laser work in the plastic surgery of wrinkles and scars?
As you know, in plastic surgery and cosmetology, there are two ways to influence the skin in order to eliminate wrinkles – this is skin tightening and its polishing. The first method is based on stretching the skin and excising its excess, and the second method is based on leveling its surface. To smooth the surface of the skin, both chemical factors and physical effects are used. Unlike microdermabrasion, laser resurfacing does not consist in direct cleansing of the surface layers of the skin – the essence of laser resurfacing is the effect of laser energy on the surface layers. At the same time, in the depths of the wrinkle, the laser has a stimulating effect on the growth of collagen fibers, which themselves will fill the wrinkle cavity as they are synthesized. That is, as you can see, the laser has a double effect, which is an important feature of laser resurfacing.
A feature of the so-called. low-intensity laser radiation (N-Lite laser) is that, like other types of laser, it does not have such an effect on the surface layers of the skin, that is, it does not grind it in the truest sense of the word. But its effect is that it stimulates the synthesis of collagen in the depths of the skin, which leads to a natural smoothing and renewal of the skin. In addition, an important advantage of such laser therapy is that it is completely painless, does not require anesthesia and a recovery period, and, accordingly, is devoid of the risk of typical complications.
