Laser rejuvenation is no longer something rare and mythical. Nowadays, anyone can turn back the years they lived. But not all people have reliable information about laser rejuvenation methods, as a result of which they make a mistake when choosing a 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:
hard (full);
fractional (incomplete).
Perhaps at first glance, these methods of laser rejuvenation look similar, but this is far from the case. Only the result is the same: after correctly selected types of procedures, the skin becomes several years younger and really looks much better.
Non-ablative laser treatment works with the deeper layers of the skin by warming 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 layers of the skin is also improved.
This method is most effective when:
scars and serious skin damage;
extensive rashes;
hyperpigmentation and uneven complexion;
after acne;
stretch marks
Non-ablative treatment is based on erbium laser work. 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 made not only on the lower, but also on the upper layers of the skin. Through the ablative method, the texture of the skin is leveled and a lifting effect is achieved. Applicable to:
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, since larger volumes of skin are exposed than with the non-ablative method.
Despite the differences, the essence of both methods is the same. With the help of 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 started.
Fractional and continuous laser irradiation
Although they give approximately the same results, these two methods have significant differences.
In long-term laser treatment, the laser affects the skin in one large spot. However, due to the too high risk of scars and long recovery periods, this type of laser treatment is now practically not used anywhere.
In another case, the laser is split into many small beams that form a grating. 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 non-ablative, works with the deep layers of the skin. But they are by no means the same or interchangeable.
The finest 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.
Laser photorejuvenation uses devices such as KTP (wavelength 532 nm) and ND: Yag (wavelength 1064 nm). Thanks to these parameters, laser radiation is perfectly absorbed by hemoglobin and melanin molecules, which are responsible for skin pigmentation. At the same time, water molecules are practically not heated. For these reasons, laser photorejuvenation is an extremely effective tool for correcting skin color and fighting vascular networks on it.
This technique does not require a long period of rehabilitation and anesthesia.
Finally
Each method of laser skin rejuvenation has its own unique characteristics that significantly affect the final result. It is necessary to carefully select a technique so that rejuvenation is not only an easy and effective, but also a safe process.
It is worth knowing that some cosmetologists do not disclose to the client all the features of this procedure and choose a device for laser treatment on the principle of "what is there". To avoid this, you should contact experienced specialists with experience who have proven themselves positivelyduring the entire period of work.
