CO2laser is widely used in the esthetic medicine and cosmetology, since it allows immediate local evaporation of tissues of the integument and mucosa resulting in local tissue destruction and removal. CO2 laser was introduced into medical practice more than 40 years ago.

CO2 laser belongs to infrared lasers. Its radiation is absorbed by water containing in the human tissues in large amounts. Explosive evaporation of water occurs in the point of the laser beam focus, with the remaining cells and intercellular substance burnt down.

The main types of CO2 lasers include continuous-wave and pulsed lasers.

Continuous-wave lasers produce continuous radiation. They are used in surgery for tissue dissection. In these lasers, a considerable part of energy is transmitted to the surrounding tissues.

Pulsed lasers produce radiation in the form of short flashes. During these flashes, a large part of energy is transmitted to the tissues, which results in the destruction of the cells in the exposed area. In this case, heat is not transmitted to the surrounding tissues. Local effect of this type of laser contributes to prompt healing of the treated skin and mucosa. The majority of modern lasers can work both in continuous-wave and pulsed modes.

Fields of application of CO2laser in cosmetology:

  1. Procedure of fraction photothermolysis (laser resurfacing).
  2. Removal of neoplasms of various etiology and localization.
  3. Removal of pigmented spots.

Laser resurfacing

The procedure of laser resurfacing is performed using LumenisAcu Pulse Laser (USA). It is indicated if the patient has the following problems: post-acne, acne; mimic wrinkles, scars of various localization, hyperpigmentation, hyperkeratosis and striae.

Before the procedure, the doctor-cosmetologist should inform the patient about indications and contra-indications, as well as about the protocol of conducting the procedure and the patient’s behavior after the procedure.

The procedure is performed under local anesthesia. Anesthetic cream is applied to the area of exposure. Then, the skin is exposed to multiple micro-perforations. Following the procedure, the skin is covered with a thin crust, which is rejected after 7-10 days. During the rehabilitation period, the patient should follow all the doctor’s recommendations.

Removal of neoplasms

The following neoplasms can be removed at the Dispensary: pigmented nevus, papillomas, seborrhealkeratomas, viral warts of various localization, gemmangiomas (up to 5 mm in diameter), dermatofibromas.

LumenisAcuPulse Laser allows an effective and safe removal of neoplasms of various localizations. It is performed under local anesthesia with the help of a laser beam by means of gradual layer-by-layer evaporation of tissues with intricate accuracy. The procedure is painless and bloodless.

Before the removal of a pigmented nevus, consultation of the doctor-oncologist is required in a number of cases.

The procedure of laser removal may be combined with histologic investigation, if necessary. This may be important for verification of a diagnosis and can also be made by the requirement of the patient.

Pint-point removal of pigmented spots

 Problematic zones are treated with the help of a nozzle for laser resurfacing. In the course of time, the cells with normal amount of pigmented granules start growing in these areas. Following the procedure, the patient may develop swelling, redness and later peeling in the exposed area. In order to reach a good result, 3-4 procedures are needed. 

Thus, a wide range of medical services with the use of CO2 laser can be provided at “Minsk Regional Dermatovenerological Dispensary”. Experienced specialists will answer all the questions about the protocols of performing the procedures and will give useful recommendations concerning the rehabilitation period.
