Innovative laser skin rejuvenation RecoSMA (Reconstruction Space Modulated Ablation) procedure occupies a special position in a number of techniques patented by Linline. A unique feature of this technique is the impact on a number of age-related changes not only in the surface layers of the skin, but also in the underlying tissues.
Skin rejuvenation using the RecoSMA procedure is performed by Er:Yag laser with a wavelength of 2936 nm, the laser is equipped with a special SMA module. The SMA module is a lens system that provides redistribution of energy flow. When the laser acts on the skin, a light spot with a diameter of 5 mm is formed, and in this spot, due to the operation of the SMA module, zones of 50 microns in size are created, in which the laser exposure alternates from minimum to maximum degree. These alternating effects serve as a signal to enhance the synthesis of new collagen and elastin, the formation of new cells, not affected by age-related changes.
How and due to what processes does laser tissue rejuvenation take place
The RecoSMA procedure is a method of interference acoustic microtrauma of tissues. On the treated skin surface with the help of the SMA module, an ordered structure of maximum and minimum radiation doses is formed. Optimal energy density values (2-3 J/cm2) and the duration of the laser pulse lead to the formation of local areas of microablation with a depth not exceeding the thickness of the epidermis. The density of damage microzones is 10 000 per square centimeter.
As a result of microablation, local volumetric expansion of tissues occurs, which leads to the formation of acoustic waves that penetrate the skin to a depth of 6 mm. The power of individual waves is not enough to destroy cells. However, at the level of the dermis and deeper structures (ligamentous apparatus SMAS), acoustic waves interfere with an increase in the local power of the latter and mechanical destruction of cell membranes, nuclei and cytoplasm. As a result, damage zones commensurate with the size of individual cells are formed inside the treated tissue, which are located among other undamaged cells. In this case, there is no thermal component and contact of the damage zone with the environment. Consequently,
The described processes serve as a signal for the growth of new cells, but without those age-related changes that were characteristic of the destroyed ones. At the same time, collagen synthesis is enhanced & nbsp; and elastin.
Indications for laser tissue rejuvenation and effects
The current indications for RecoSMA rejuvenation procedure are:
- age-related structural and deformation changes in the skin and underlying tissues;
- prevention of gravitational ptosis;
- photoaging;
- enlarged pores.

The number of RecoSMA procedures is determined by the doctor depending on the patient's skin condition and can be performed both once and as a course. The interval between procedures is usually three months or more. The RecoSMA method can be successfully combined with other aesthetic correction procedures.
