Laser rejuvenation is no longer something rare and mythical. Nowadays, everyone can go back to the years they lived. However, not all people have reliable information about laser rejuvenation methods, which is why they make mistakes when choosing the procedure.
First of all, you need 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 far from the case. But the result is the same: after properly selected types of treatments, the skin looks several years younger and actually looks much better.
Non-ablative laser treatment works on the deep layers of the skin, heating them. The impact of the laser beam energy on the fibroblasts causes them to produce collagen and elastin at an accelerated rate. Microcirculation in the skin layers also improves.
This method is most effective when:
scars and severe damage to the skin;
extensive skin rashes;
hyperpigmentation and uneven complexion;
post-acne;
stretch marks.
Non-ablative treatment is based on the operation of an erbium laser. Due to the special wavelength (1550 nm), the upper layers of the skin are not affected, while the lower layers receive the stimulation necessary for 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 10, 600 nm. The impact is carried out not only on the lower, but also on the upper layers of the skin. Using the ablative method, the skin texture is evened out and a lifting effect is achieved. Applicable for:
wrinkles around the eyes, small facial wrinkles;
decrease in 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 both 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 is launched.
Fractional and continuous laser exposure
Although they provide approximately the same results, these two methods have significant differences.
With continuous laser treatment, the laser affects the skin in a large spot. However, due to the very high risk of scarring and long recovery times, this type of laser treatment is practically not used anywhere.
In another case, the laser is divided into several small beams that form a grid. Thus, the laser, interacting with only 20% of the skin area, achieves a 100% rejuvenation effect. This method is more modern and safe, with its use the rehabilitation time is significantly reduced.
Laser photorejuvenation
This rejuvenation technique, like the non-ablative one, works in the deep layers of the skin. But they are by no means the same or interchangeable.
The best laser beams almost completely "bypass" the dermis, but have an excellent effect on the nerve endings in the skin, which give the body a signal to renew cells. 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 the 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 for correcting skin color and combating skin vascular networks.
This technique does not require a long period of rehabilitation and anesthesia.
Finally
Each laser skin rejuvenation method has its own 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 important to know that some cosmetologists do not disclose to the client all the features of this procedure and choose a device for laser treatment based on the principle of "what is available". To avoid this, you should contact experienced and experienced specialists who have positively proven themselves throughout the entire period of work.
