Laser rejuvenation is no longer something rare and mythical. Nowadays, everyone can go back in time. However, not all people have reliable information about laser rejuvenation methods, so they make a mistake when choosing a procedure.
First of all, it is necessary to understand the types of procedures. There are two of them:
ablative;
non-ablative.
In turn, these types of impacts are divided into:
solid (full);
fractional (incomplete).
Perhaps at first glance these laser rejuvenation methods may seem similar, but this is not the case. Only the result is the same: after correctly selected types of treatment, the skin rejuvenates for several years and really looks much better.
Non-ablative laser treatment works with the deep layers of the skin, warming them. The impact of the laser beam energy on the fibroblasts causes them to produce collagen and elastin at an accelerated rate. It also improves microcirculation in the skin layers.
This method is most effective when:
scars and severe skin damage;
extensive rashes;
hyperpigmentation and uneven complexion;
post-acne;
stretch marks.
Non-ablative treatment is based on the operation of an erbium laser. Thanks to the special wavelength (1550 nm), the upper layers of the skin are not affected, while the lower layers receive the stimulation necessary for their restoration. 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 on the lower, but also on the upper layers of the skin. With the ablative method, the skin texture is unified and a lifting effect is achieved. Applicable for:
wrinkles around the eyes, small facial wrinkles;
decreased skin tone;
pigmentation disorders.
It is worth noting that the rehabilitation period after this procedure will be slightly longer, as larger volumes of skin are exposed than with 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 evaporated. At the same time, the synthesis of collagen and elastin necessary for rejuvenation begins.
Fractional and continuous laser exposure.
While they give approximately the same results, these two methods have significant differences.
With continuous laser treatment, the laser affects the skin over a large area. However, due to the too high risk of scar formation and long recovery times, this type of laser treatment is practically not used anywhere.
In another case, the laser is divided into many small beams that form a grating. Thus, the laser, by interacting with only 20% of the skin area, achieves a 100% rejuvenation effect. This method is more modern and safer, with its use the rehabilitation time is significantly reduced.
Laser photorejuvenation
This rejuvenation technique, like the non-ablative one, works with the deep layers of the skin. But they are in no way equal or interchangeable.
The finest laser rays almost completely "ignore" the dermis, but have an excellent effect on the nerve endings in the skin, which send the body a signal to renew cells. Fine wrinkles disappear and skin tone is recovered.
Devices such as KTP (wavelength 532 nm) and ND: Yag (wavelength 1064 nm) are used in laser photorejuvenation. Thanks to these parameters, laser radiation is perfectly absorbed by hemoglobin and melanin molecules, responsible for skin pigmentation. At the same time, water molecules are practically not heated. For these reasons, laser photorejuvenation is an extremely effective tool to correct skin color and combat its vascular networks.
This technique does not require a long period of rehabilitation or anesthesia.
Finally
Each laser skin rejuvenation method has its own unique characteristics that greatly influence the final result. It is necessary to carefully select a technique so that rejuvenation is not only easy and effective, but also a safe process.
It is worth knowing that some cosmetologists do not reveal to the client all the features of this procedure and choose a device for laser treatment on the principle of "what is available. "To avoid this, you should contact experienced specialists who have proven themselves throughout the entire period of work.
