Laser rejuvenation is no longer a strange and mythical thing. Nowadays, everyone can go back to the years they have lived. However, not everyone has reliable information about laser skin rejuvenation methods, so they make mistakes when choosing a method.
First of all, you need to understand the types of procedures. There are two of them:
invade;
Non-abrasive.
These types of impacts are, in turn, divided into:
solid (full);
fraction (incomplete).
Perhaps at first glance, these laser rejuvenation methods seem similar, but in fact they are not. Only the result is the same: after choosing the right treatment, the skin will become several years younger and really look much better.
Non-invasive laser treatments act on the deep layers of the skin, warming them. The impact of laser beam energy on fibroblasts causes them to produce collagen and elasticity at a faster rate. Microcirculation in the skin layers is also improved.
This method is most effective when:
scarring and severe skin damage;
widespread rash;
hyperpigmentation and uneven skin tone;
after acne;
stretch marks.
Non-invasive treatment based on the action 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 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 carried out not only on the lower layer, but also on the upper layers of the skin. Using abrasion, the skin texture is evened and a lifting effect is achieved. Apply for:
wrinkles around the eyes, small wrinkles on the face;
reduced skin tone;
pigmentation disorders.
It is worth noting that recovery time after this procedure will be slightly longer because the amount of skin exposed is greater than with a non-excision method.
Although there are differences, the essence of these two methods is the same. Using the energy of a laser beam, the water in the dermis is literally heated and evaporated. At the same time, the synthesis of collagen and Elastin necessary for rejuvenation is initiated.
Fractional and continuous laser exposure
Although the results are nearly identical, these two methods have significant differences.
With continuous laser treatment, the laser hits the skin in one large spot. However, because the risk of scarring is too high and the recovery time is long, this laser treatment method is practically not used anywhere.
In another case, the laser is divided into many small beams forming a grid. Thus, the laser only interacts with 20% of the skin area to achieve 100% rejuvenation effect. This method is more modern and safer. When used, rehabilitation time is significantly reduced.
Laser skin rejuvenation
This rejuvenation technique, like non-invasive techniques, works with the deep layers of the skin. But they are not the same or interchangeable.
The best laser beams almost completely "bypass" the dermis, but have an excellent effect on nerve endings in the skin, helping the body send signals to regenerate cells. Small wrinkles disappear, skin tone is restored.
In laser light skin rejuvenation, 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 hemoglobin and melanin molecules, substances 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 in correcting skin color and fighting its vascular network.
This technique does not require a long recovery time or anesthesia.
Final
Each laser skin rejuvenation method has its own characteristics that greatly affect the final results. It is necessary to choose techniques carefully to make rejuvenation not only easy and effective but also safe.
It is worth knowing that some cosmetologists do not disclose to customers all the features of this procedure and choose a laser treatment device according to the principle of "what is available". To avoid this, you should contact experienced specialists who have proven themselves positively during their work.
