Fractional laser is nowadays an increasingly popular tool in the fight against wrinkles and acne scars. It works by causing a series of micro-damages in the skin separated by fragments of healthy tissue.

Fractional laser – how does it work?

The main difference between the traditional and fractional laser is the surface of the tissue subjected to therapy. With the fractional method the laser beam is dispersed, as if passing through a sieve, covering only points on the surface of the treated tissue. Thus, during the treatment the laser affects about 20-25% of the treated area, creating microscopic defects. These microcolumns of damage create inflammation, which stimulates fibroblasts of healthy adjacent tissue to produce new collagen.

Fractional laser – effect

The effects of the fractional method depend on the type of laser with which the procedure is performed. Fractional lasers are divided into ablative and non-ablative. Light of ablative laser penetrates deep layers of skin, where it is absorbed by water contained in cells. It is immediately heated and then evaporated, accompanied by damage to the epidermis

After the procedure, spot bleeding occurs, which then turns into small scabs that last from a few days to up to two weeks. But once everything has healed, you can admire the effects of the laser: the skin is tighter and smoother, and its color is even

Non-ablative laser affects the deep layers of the skin much more gently, without interrupting the continuity of the epidermis. This type of laser is less aggressive, does not “perforate” the skin, but also does not give such effects as ablative laser.

Therefore, both lasers have their pros and cons. Treatment with ablative fractional laser requires convalescence, but its effects are visible after the first treatment. With its help you can get rid of deep wrinkles and pigmentation spots, acne discoloration, scars and stretch marks

On the other hand, non-ablative method does not carry the risk of infection, does not require convalescence, but also does not bring rapid effects in the form of skin rejuvenation. This type of photothermolysis is recommended for people under 40 years of age who have observed the first signs of skin aging: loss of tension and fine wrinkles.

Fractional laser treatment – the course

Two weeks before the scheduled treatment you can not use the solarium and sun bath. You should also not use chemical peelings. Three days before the treatment it is best to stop going to the pool and sauna. To prevent complications cosmetologist can also apply antiviral and antibacterial preparations. Twenty-four hours before the treatment you should refrain from stimulants such as cigarettes and alcohol.

Before the treatment the skin is cleaned and disinfected. The impact of the laser is felt as an unpleasant sting, but sometimes there may be a need for anesthesia. In this case, the doctor or cosmetologist applies an additional anesthetic. Once the ointment takes effect, the skin is treated with the laser. The duration of the procedure depends on the area of skin to be treated and ranges from a few minutes to up to an hour. After the procedure, a soothing mask is applied to the skin.
