After the introduction of lasers to the medical sector, there have been serious advances in the field of cosmetic dermatology. Fractional Lasers have become the most effective treatment methods used by dermatologists in the treatment of spots, skin cracks and wrinkles in addition to all kinds of permits such as acne scars, burn scars, and surgical scars. These lasers have also improved greatly over the past years. Fractional lasers are the newest link in laser technologies known as ablative lasers. These laser systems have been used for a long time. They are especially preferred in scar treatments and skin rejuvenation applications. Fractional lasers are technologically different from conventional ablative lasers.
Lasers used for scar treatment used to peel off the entire surface. For this reason, although the effect was good, they would cause a lot of side effects. Healing periods that may last for months and scar problems that occurred while healing prevented this method from becoming common. Fractional treatment has emerged due to the search for treatment that heals faster and has less side effects. With fractional laser, the process of opening micro channels in the skin occurs without peeling the epidermal tissue, the opportunity to treat both the epidermis and the dermis comes out. Since the tissues around these microchannels remain intact and there is no thermal damage, healing occurs quickly. These very small wounds that are created heal like the wounds formed in other parts of the body and heal the top layer of the skin, eliminate wrinkles, remove wrinkles and reduce acne scars. The regeneration and reconstruction of collagen fibers continues for a year after the procedure.
Fractional lasers have become the new standard in this way, but the problems do not end there. In order to decrease the side effect, the search for a more effective application was born and this caused the need for the development of fractional lasers. Fractional lasers differ according to the type of laser light used. Erbium fractional lasers and CO2 fractional lasers, as two main groups, can offer very different results depending on the features they have.
Erbium laser therapy is a method for safe, controllable tissue ablation. The wavelength of this laser can be absorbed 13 times faster than CO2 laser radiation in water. Since the tissue provides evaporation/ablation of the water very quickly, the damage does not remain on the skin continuously and does not create nonspecific heat damage.
- CO2 fractional lasers: CO2 (carbon dioxide) lasers can reach deep into the skin even in one shot due to the wavelength they use. It also causes regeneration in the skin as it causes thermal damage to the tissue. In this way, it can provide effective results in scars and wrinkles. However, due to the high thermal effect, the healing process may be delayed and stains may occur. Er Yag lasers, on the other hand, have become more widespread due to their effective depth and their side effects are much less than CO2 lasers.
By opening very small channels into the skin, a very rapid regeneration, tightening and recovery occurs in both the upper and lower layers of the skin. Due to these features, it is successfully used for removing wrinkles on the skin, reducing acne scars, reducing cracks in the skin, removing surgical and wound scars, and removing age spots on the hands and face.
Areas of Usage
Treatment of Acne Scars
After acne is treated by a dermatologist or after the acne problem disappears spontaneously, scars may remain. Since these are in the form of small and large pits on the skin, they can cosmetically disturb the patient. With fractional laser, the scars will greatly decrease in an average of 3-6 sessions. After the application, the downtime, that is, the period of redness is quite short, which allows patients to easily return to their daily lives.
Surgical Scars, Keloid, Laser Treatment of Burn Scars
In medicine, there is no method that can completely eliminate scars. However, with fractional laser, swollen scars on the skin can be softened, lowered to the skin level, redness can be corrected, even mature marks can be improved. Again, it is very effective in reducing the sequels due to burns and softening the grafts.
Facial Rejuvenation, Wrinkle Treatment
Fractional laser is a very effective treatment method to make the skin better, lively and bright. Especially superficial and moderate wrinkles can be eliminated with this treatment, while deep wrinkles will be reduced. The narrowing and tightening of the pores occur. Three to five sessions should be performed at 3-5-week intervals.
Hand Rejuvenation
As a result of regular applications with fractional laser, the wrinkles in the hand improve. With Er Yag laser, dark lesions in this region can be removed.
Beauty Spot (nevus) Treatment with Laser
Nevi, i.e. beauty spots, can be surgically removed or treated with laser. Nevi to be removed by laser must be benign. Epidermal and dermal nevi can be treated with laser, while lesions and skin cancers with very deep roots must be surgically removed. Benign beauty spots can be treated with Er Yag laser in one session, without leaving a scar.
LASER TREATMENT FOR SKIN DISCOLORATION
Spot treatment is a time-consuming treatment. The type of spot is very important. The sun triggers spots. Sunspots, melasma, pregnancy spots, and age spots can be treated with laser.
Crack Treatment with Laser
Cracks (striae) are the tears of the skin and subcutaneous tissue, that is, a kind of scar. There is no cure for crack like scars, but with fractional laser, the clarity of cracks can be reduced in 5-6 sessions.
