Laser rejuvenation is no longer something rare and mythical. Now everyone can turn back the years they lived. However, not all people have reliable information about laser rejuvenation methods, as a result, they make a mistake when choosing a procedure.
First, you need to understand the types of procedures. There are two of them:
ablative;
non-ablative.
In turn, these types of effects are divided into the following:
solid (complete);
fraction (incomplete).
Perhaps, at first glance, these methods of laser rejuvenation may seem similar, but they are far from it. Only the result is the same: after correctly selected types of treatment, the skin becomes younger for several years and looks really better.
Non-ablative laser treatment works with the deeper layers of the skin, heating them. The effect of laser beam energy on fibroblasts causes them to rapidly produce collagen and elastin. Microcirculation in the layers of the skin also improves.
This method is most effective in the following cases:
scars and severe skin damage;
extensive rashes;
hyperpigmentation and uneven skin;
post-acne;
stretch marks.
Non-ablative treatment is based on the operation of the erbium laser. Thanks to the special wavelength (1550 nm), the upper layers of the skin are not affected, while the lower layers receive the necessary stimulation for recovery. As a result, most defects are eliminated.
Ablative laser treatment works a little differently. This method uses a carbon dioxide laser with a wavelength of 10600 nm. The impact is carried out not only in the lower, but also in the upper layers of the skin. Using the ablative method, the skin texture is evened out and a lifting effect is achieved. Being applied:
wrinkles around the eyes, small facial wrinkles;
decrease in skin tone;
pigmentation disorders.
It should be noted that the rehabilitation period after this procedure will be a little longer, since a larger volume of skin is exposed compared to the non-ablative method.
Despite the differences, the essence of the two methods is the same. Using the energy of the laser beam, the water in the dermis is heated and literally evaporates. At the same time, the synthesis of collagen and elastin, necessary for rejuvenation, is activated.
Fractional and continuous laser exposure
Although these two methods give almost the same results, there are significant differences.
With continuous laser treatment, the laser affects the skin in one big spot. However, due to the very high risk of scarring and long recovery times, this type of laser treatment is now practically not used anywhere.
In another case, the laser is divided into many small beams that form a network. Thus, the laser achieves a 100% rejuvenation effect by interacting with only 20% of the skin area. This method is more modern and safe, with its use, the rehabilitation period is significantly reduced.
Laser photorejuvenation
This rejuvenating technique, as non-ablative, works with the deeper layers of the skin. But they are by no means identical or interchangeable.
The thinnest laser beams almost completely "ignore" the dermis, but have an excellent effect on the nerve endings in the skin, which give the body a signal for cell renewal. Fine wrinkles disappear, skin tone is restored.
In laser photorejuvenation, devices such as KTP (wavelength 532 nm) and ND: Yag (wavelength 1064 nm) are used. Thanks to these parameters, laser radiation is perfectly absorbed by hemoglobin and melanin molecules responsible for skin pigmentation. At the same time, water molecules practically do not heat up. For these reasons, laser photorejuvenation is an extremely effective tool in correcting skin color and fighting vascular networks on it.
This technique does not require a long rehabilitation period and anesthesia.
Finally
Each laser skin rejuvenation method has its own characteristics that greatly affect the final result. In order for rejuvenation to be not only easy and effective, but also a safe process, it is necessary to carefully choose a technique.
It should be known that some cosmetologists do not disclose all the features of this procedure to the client and choose a device for laser treatment on the principle of "what is available". To avoid this, you should contact experienced professionals who have proven themselves positively throughout the entire working period.
