Laser rejuvenation is no longer something rare and mythical. Nowadays, everyone can relive the years they have passed. However, not everyone has reliable information about laser rejuvenation methods, as a result of which they make mistakes when choosing the procedure.
First of all, you need to understand the type of procedure. There are two of them:
ablative;
not ablative.
Instead, this type of impact is divided into:
solid (full);
fraction (incomplete).
Perhaps at first glance, this method of laser rejuvenation may seem similar, but this is far from the case. Only the result is the same: after the right type of treatment, the skin becomes several years younger and really looks better.
Non-ablative laser treatments work with the inner layer of the skin, heating it up. The effect of laser beam energy on fibroblasts causes them to produce collagen and elastin at an accelerated rate. Microcirculation in the skin layer is also improved.
This method is most effective when:
serious scarring and skin damage;
widespread rash;
hyperpigmentation and uneven skin;
after acne;
stretch marks.
Non-ablative treatment is based on erbium laser operation. Due to the special wavelength (1550 nm), the upper layer of the skin is not affected, while the lower layer receives the stimulation necessary for recovery. As a result, most defects are eliminated.
Ablative laser treatments work a little differently. This method uses a carbon dioxide laser with a wavelength of 10600 nm. The effect is done not only on the bottom, but also on the top layer of the skin. Using the ablative method, the skin's texture becomes even and a lifting effect is achieved. Used for:
wrinkles around the eyes, small facial wrinkles;
reduce skin tone;
pigmentation disorders.
Keep in mind that the recovery period after this procedure will be slightly longer, because a larger amount of skin is exposed than with non-ablative methods.
Despite the differences, the essence of both methods is the same. Using laser beam energy, 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 giving more or less the same results, these two methods have significant differences.
With continuous laser treatment, the laser affects the skin in one large area. However, due to the high risk of scarring and the long recovery time, this type of laser treatment is now practically not used everywhere.
In other cases, the laser is divided into many small beams that form a grid. Therefore, 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, recovery time can be significantly reduced.
Laser photo rejuvenation
These rejuvenation techniques, like non-ablative ones, work with the inner layers of the skin. But they are by no means the same or interchangeable.
The best laser beams almost completely "ignore" the dermis, but have an excellent effect on the nerve endings in the skin, which signal the body 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 this parameter, laser radiation is perfectly absorbed by hemoglobin and melanin molecules, which are responsible for skin pigmentation. At the same time, water molecules can be said not to be hot. For these reasons, laser photorejuvenation is a very effective tool in correcting skin color and combating the vascular network on it.
This technique does not require a long recovery period and anesthesia.
Finally
Each method of laser skin rejuvenation has its own unique characteristics that greatly affect the final result. It is necessary to carefully choose the technique so that rejuvenation is not only easy and effective, but also a safe process.
It should be noted 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 an experienced specialist with experience who has proven themselves positively during the period of work.
