How does laser fractional photothermolysis work on the skin
The fractional mode of operation of laser equipment is carried out by dividing the beam into small beams that are capable of penetrating into the deeper layers of the skin and damaging it pointwise. After the procedure, regeneration processesare activated on intact skin areas, elastin and collagen are synthesized, which is accompanied by a lifting- effect .
Thus, some separate areas of the skin are intentionally damaged in order to start the regeneration processes.
Clinical studies have made it clear that such a division of the laser beam into fractions during photothermolysis allows you to get the same result as with laser resurfacing. But with photothermolysis, the patient does not require long-term rehabilitation.

Fractional photothermolysis exists in 2 types - ablative and non-ablative.
- Ablative photothermolysis is performed using a CO2 laser whose beam damages the dermis in its deep layers. Coagulation and destruction of proteins in the superficial layers of the skin occur. Within 3 months, new collagen is formed in the area of action.
This photothermolysis is used to eliminate scars, deep wrinkles, sagging skin, age spots, scars and scars.
- Non-ablative photothermolysis is used to improve the appearance of the face, eyelids, neck, as well as to eliminate post-acne and stretch marks. This type of photothermolysis is not accompanied by damage to the dermis, the erbium laser beams penetrate under the epidermis and do not damage it.
More often this type of photothermolysis is used to eliminate age spots, as melanin is redistributed. The effect of non-ablative photothermolysis is prolonged.
Stages of photothermolysis. Skin care after treatment
10 days before the photothermolysis session, it is important to do not peel or scrub, stop using products that contain salicylic acid, retinol and glycoic acid.
The skin is cleaned, a local anesthetic is applied, then the skin is covered with an ointment to better glide the device nozzle over the skin. Procedure painless. The average time for one session is 30-40 minutes. At the end of the procedure, a cream with soothing properties is applied to the skin.
