CO2 laser (carbon dioxide laser) is a principle of action, before and after photos
Mechanism of action
It belongs to the infrared lasers. Its radiation is absorbed by water, which in large quantities contained in the tissues. In place of focusing of the light beam occurs the explosive evaporation of water, the remaining cells and the intercellular substance is burned.
In the center of the impact zone of the beam, the temperature rises to more than 100C. At the edges of the region of tissue die off a layer of 30-40 microns. Blood vessels in the affected area whose diameter does not exceed 1 mm, sealed, and larger ones can give spot bleeding.
In this kind of lasers radiation is constantly on time. They are used in surgery for tissue dissection and removal of skin lesions and mucous membranes.
The only drawback is their considerable heating of the surrounding tissue. Hence the inability to accurately predict the depth of the tissue.
In this kind of laser radiation is applied in short bursts. Each pulse passes the tissue considerable energy, because the cells in the affected area die and evaporate.
The transfer of heat to the tissues around the zone of laser radiation virtually no heat and remain viable. Subsequently, such a selective action, promotes rapid healing of skin and mucous membranes.
Pulse frequency less than 5 Hz is used for the application of perforations to the skin (fractional laser resurfacing), more than 5 Hz for cutting fabrics.
Most modern lasers can operate in continuous and pulse modes.

Fractional laser resurfacing
In beauty salons this method is becoming increasingly popular procedure. Usually regardless of brand and manufacturer of laser treatments standard Protocol.
Frequency and power is adjusted so that one pulse has removed a section of the epidermis with a thickness of 20-30 microns. Exhibiting not more than 5 Hz to avoid deep tissue heating, which can lead to uncontrolled damage.

One procedure is performed 1-4 pass through the skin with a laser:
- The first pass destroys the epidermis by 40-70 µm with and target tissues, and cells damaged in the affected area by heat. Dehydrated protein residue that remains on the surface of the skin, easily removed with a cloth soaked in saline solution. In fact, the first impact is preparatory.
- On the entire surface of the skin makes the second pass. On the skin of the eyelids second «layer» of the laser radiation is applied only to the reduced power or not applied at all.
- The third pass is performed on areas of the skin with the most pronounced wrinkles, scars.
- A fourth pass is required only in exceptional cases when it is necessary to intensively influence the scar tissue.
Performance criteria (how to determine what the impact of the laser radiation is enough):
- the region of wrinkles and scars treated;
- the subsequent passage is not observed further reduction of the skin;
- when wiping the skin with saline, there are signs of thermal necrosis.

The stages of work with the client during laser resurfacing
- Preparation for the procedure.
At the consultation the doctor will determine the justification for use laser resurfacing to address skin problems and gives explanations on the fact, as will be the procedure and recovery period afterwards. Usually a week before the procedure, you must start taking antiviral drugs to prevent recurrent herpes.
You should consider the fact that taking photosensitizing medications (Roaccutane, isotretionin, local retinoids, doxycycline, and others). Drugs that can increase skin sensitivity to light, a large number, because the doctor should tell about all the pills and cosmetic products that you take and apply.
The procedure needs to come in at least 30 minutes before the start. We need this in order to the doctor enough time to carry out anesthesia.
If you plan on single pass and second pass locally on small scars or other skin imperfections, it is typically sufficient local anesthesia, which is conducted by cream «EMLA». Typically, the ointment is applied under the film for up to 60 minutes.
If to eliminate defects and excess skin will need 3 passes and locally a fourth, it could be total intravenous anesthesia. In this case, the procedure is the anesthesiologist, and he advises the client before the procedure to identify contraindications to anesthesia.
- Treatment of the skin before the procedure.
Before the skin is cleansed. If applied «EMLA», then it is removed. Wipe face with a special lotion.
- Conduct laser resurfacing.
Directly skin treatment laser takes about 20-30 minutes, depending on the number of passes. Then applied to the skin soothing cream or special lotion to restore the skin’s moisture level.
- A recovery period.
Here everything is very individual.
One pass of the laser can have a small redness and slight peeling. Usually after this treatment on the third day you can go out and safely get to work.
Two or three passes will give a pronounced redness that will persist for about 4-6 weeks. Severity of redness will be intense the first week or two, then a pink complexion will be masked by makeup. In those places, where I made three passes with the laser beam, it is possible to expect the appearance of bloody crusts, rip off which is impossible. Under the crust is the formation of young skin. Peel can go 5-10 days.
Local impact performed in 4 calls, can give ulcers covered with crusts or long-term bleeding. To heal these sores can two to three months. If the proper procedure, skin blemishes with this approach are well smoothed.
In the first week after the procedure should be applied on the face cream panthenol. The second tetracycline or other antibacterial ointment on the recommendation of a physician.
- Complications of the procedure.
The meaning of the carbon impact of the laser on the skin is that its beam burns the tissue of small holes, and the contents of these holes evaporate. The total volume of the holes can reach 10% of the volume of the skin.
In the ideal case, when the procedure is performed correctly from a technical point of view, is reduced only in the area of the epidermis with the capture of the uppermost layer of the dermis. This depth of damage is optimal for further regeneration. In this case, the area of the skin by tightening the edges of wounds is reduced and the face significantly tightened.
If the doctor does not correctly calculate the thickness of the skin of the patient (ideally, the thickness of the dermis and epidermis determine each patient separately using ultrasound), at the site of damage to the skin by the laser can occur in whitish areas of skin that have killed the melanocytes responsible for skin pigmentation.
If the damage was even deeper, at the site of wounds, forms scar tissue. In this case, there is a so-called «Marley effect» when areas of normal skin interspersed with ridges in the form of «boxes», arranged in neat rows.
Removal of pigment spots and melasma
The removal of excessively pigmented cells CO2 laser is a point. On the area of skin to apply the laser Microperforation. In the field of point damage starts to grow cells with normal levels of pigment. After the procedure, the skin appears a slight swelling and redness followed by peeling.
In order to remove an area of increased pigmentation, usually need 3-4 treatments.
Use in dermatology
Doctors dermatologists use CO2 laser for removal of skin formations such as flat warts, pigmented nevi, benign skin. If in cosmetology often apply the frequency pulses to perform the perforation in dermatology often requires a complete «burning» of the tissue.
Superficial warts are amenable to such methods of influence as cryotherapy, electrocautery. Deep warts can only be removed with a laser. Removed the carbon laser warts of any location, including deep plantar. The procedure is performed under local anesthesia. After the laser exposure the skin is a little redness and peeling.
To remove laser nevus of right
Usually remove those moles, which are often injured, to prevent malignancy (degeneration into melanoma). Before you remove the mole, you must consult an oncologist and if indicated to do a biopsy (take a piece of fabric moles on analysis).

If a mole everything is fine (no signs of malignant growth), its diameter less than 1 cm, you can remove it by laser. Nevi larger diameter are often removed surgically. Before the procedure under the mole is injected anesthetic, then to the very destruction of skin lesions was absolutely painless.
In place of the removed mole remained small wound, which can first few days to get wet. You need to handle it with green paint or other antiseptic on prescription. Then the wound heals without a trace.
Removal of papillomas laser
High temperature laser beam allows to remove papilloma without a trace and scars.

Where else is used in medicine
Effective treatment possible, not only such tumors as papillomas, condylomas and cancer. Through radiation, you can remove polycystic, cervical erosion, endometriosis. Laser scalpel makes therapeutic and diagnostic laparoscopy bloodless and safe in terms of infection of the surgical wound.
- ENT diseases.
Using carbon laser treatment of snoring. This is normally one session. During the procedure is effect on the soft palate, Palatine arch and a uvula.
Kinds of equipments
Consider the main titles and producers of apparatus for laser treatment.
- Lumenis Acupulse CO2.
The device is made in the joint American-Israeli company. Designed to be used to correct defects of the skin on the face and body. The phone has technology superimpose AcuPulse, whereby each of the outbreak reports into the tissue more energy but the heating of the tissues surrounding the affected area is minimal.
- MultiPulse CO2.
Can be used not only in cosmetics but also in medicine. Has over 50 different attachments.
- Carbon laser Prosektion.
The apparatus also has superimposing mode by which to solve the problem demacation line at the border of treated and untreated skin. Often used in cosmetics.
- And SmartXide DOT SmartXide DOT2.
Made in Italy. It can be found in Russian salons and clinics often. Complaints and negative reviews more, too, about this machine.
The only thing difficult to understand from the information online, the fault is apparatus or the lack of training doctors, which on this machine are working.
These devices give often «the Marley effect» that the majority of doctors considers to be as a natural consequence of the procedure as redness and peeling of the skin.
