Devices for laser rejuvenation are represented on the market by devices for laser ablation (fixed and fractional), devices for non-ablative laser rejuvenation (erbium, neodymium, diode laser) and devices for laser phoresis. Depending on the wavelength, the laser radiation penetrates at different depths and affects precisely defined targets in the tissue (structural proteins, blood, water, pigments), so that each laser rejuvenation device solves its own aesthetic problems.
Laser ablation devices
The main goal of ablative lasers for rejuvenation is water, which evaporates during the procedure. An active process of cell renewal is set in motion in the damaged area, the skin is renewed, rejuvenated and tightened. Continuous laser ablation (laser peeling) is very painful and requires a long rehabilitation, so experts now prefer devices for fractional (point) laser rejuvenation. They are considered an alternative to surgical lifting - the results are really impressive. The fractional laser rejuvenation procedure is indicated for pronounced signs of aging: ptosis, deep wrinkles, age-related pigmentation, noticeable imperfections in the skin relief.
Devices for non-ablative laser rejuvenation
The group of devices for non-ablative laser rejuvenation is quite large. Neodymium lasers are good for removing vascular patterns from the skin (the target is blood hemoglobin). Diode lasers for rejuvenation mainly affect collagen, which leads to its remodeling and, as a result, lifting and tightening of the skin. Non-ablative erbium lasers work similarly to ablative laser rejuvenation devices - they evaporate water and damage tissue, activating regeneration - but do not affect the skin's surface.
Apparatus for laser phoresis
Devices for laserphoresis provide deep penetration of rejuvenating cocktails into the skin (most often hyaluronic acid preparations act in this role). This procedure allows you to deeply moisturize the skin, completely smooth fine wrinkles, improve the complexion and skin texture. Laserophoresis does not cause tissue heating and gently stimulates the processes of natural regeneration.
What kind of equipment to choose for laser rejuvenation is a difficult question, since the "specialization" of lasers is quite narrow. Renowned aesthetic medicine clinics use ablative lasers more often to achieve the effect of radical rejuvenation. Beauty salons offerusually non-invasive laser rejuvenation or anti-aging laser phoresis The decision to buy one or another laser for rejuvenation depends on many factors: budget, local demand, qualification of specialists.
