Laser rejuvenation is no longer something rare and legendary. Nowadays everyone can turn back the years they have lived. However, not everyone has reliable information about laser rejuvenation methods, which results in them making mistakes when choosing a method.
First of all, you need to understand the types of methods. There are two of them:
abolition;
indelible.
In turn, these types of effects are divided into:
solid (full);
fraction (insufficient).
Perhaps at first glance, these laser rejuvenation procedures may seem similar, but that is far from the case. Only the result is the same: after well-chosen types of treatments, the skin becomes several years younger and actually looks much better.
Laser treatment that is permanent works with the deep layers of the skin and heats them up. The effect of laser energy on fibroblasts causes them to produce collagen and elastin at a faster rate. Microcirculation in the skin layers is also improved.
This method is most effective when:
scars and severe skin lesions;
severe rash;
hyperpigmentation and uneven complexion;
after acne;
wear and tear
Non-ablative treatment is based on the use 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 necessary stimulation for regeneration. As a result, most defects are eliminated.
Ablative laser therapy works a little differently. This method uses a carbon dioxide laser with a wavelength of 10600 nm. The effect is not only on the lower, but also on the upper layers of the skin. By using the ablative method, the skin texture is evened out and a lifting effect is achieved. Applies to:
wrinkles around the eyes, small facial wrinkles;
decreased skin color;
pigmentary disorders.
It is worth noting that the rehabilitation time after this procedure will be slightly longer, since a larger volume of skin is exposed than with a non-abrasive method.
Despite the differences, the essence of the two methods is the same. Using the energy of the laser beam, the water in the skin is heated and literally evaporated. At the same time, the synthesis of collagen and elastin necessary for regeneration is started.
Fractional and continuous laser exposure
Although the two methods produce approximately the same results, the two methods have significant differences.
With continuous laser treatment, the laser affects the skin in one large spot. However, due to the excessive risk of scarring and long recovery time, this type of laser treatment is now used almost nowhere.
In another case, the laser is split into many small beams that form a grating. Thus, the laser, which interacts with only 20% of the skin area, achieves a 100% rejuvenating effect. This method is more modern and safer; with its use, the rehabilitation time is significantly reduced.
Laser photorejuvenation
This regenerative technique, like the non-destructive one, works with the deep layers of the skin. But they are in no way identical or interchangeable.
The finest laser beams "ignore" the dermis almost completely, but have an excellent effect on the skin's nerve endings, which signal the body to regenerate cells. Fine wrinkles disappear, skin color is restored.
Laser photography 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 practically do not heat up. For these reasons, laser phototherapy is an extremely effective tool for correcting skin tone and fighting its vascular system.
This technique does not require long rehabilitation and anesthesia.
Finally
Each laser skin resurfacing procedure has its own unique characteristics that greatly affect the final result. Careful selection of techniques is essential so that regeneration is not only 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 method and choose a device for laser treatment on the principle of "what is available. "To prevent this, you should contact experienced specialists with experiencewhich have proven successful during the entire working period.
