Ablative laser resurfacing of facial skin using a CO2 device

Laser rejuvenation can be considered one of the most effective and universal methods of combating age-related skin changes. Targets (target chromophores) for laser radiation are almost all skin chromophores - water, hemoglobin, melanin, collagen. The selectivity of laser exposure allows you to select an individual scheme for correcting involutional skin disorders for any type of aging. Skin rejuvenation using a laser resurfacing device is achieved either by layer-by-layer removal - the ablation method, or by heating the skin without violating its integrity - the non-ablative method. In this case, the beam of the laser resurfacing device can be distributed on the skin in two ways: • by completely covering its surface (with classical ablation, non-ablative photothermolysis); • by crushing (fractionation) the laser beam into several tens or hundreds of microbeams (with fractional non-ablative photothermolysis, fractional ablation).

How does the procedure work?

CO2 Light peeling takes about 20-30 minutes and consists of the following steps:

  • 40 minutes before the start of the session, the cosmetologist thoroughly cleanses the face and applies an anesthetic cream.
  • After the anesthetic has taken effect, the patient puts on protective glasses and begins the procedure.
  • As the handpiece moves across the skin, a thin laser beam evaporates tiny microzones in the upper layer of the skin (epidermis). Then, with the help of the remaining intact tissues, the process of regeneration and renewal of the skin occurs. Also, the heat of the laser beam activates the restoration of collagen in the upper layers of the skin, which promotes slight tightening of the skin and at the same time prevents aging.
  • The laser peeling procedure is completed by applying a special ointment to minimize redness and swelling.

Technique for ablative skin resurfacing using a CO2 laser resurfacing device

From a practical point of view, lasers operating in superpulse (pulse width from 1 ms to 20 ms) and ultrapulse (pulse width up to 1–3 ms) modes are better suited for laser resurfacing. According to the principle of selective photothermolysis (RR Anderson, JAParrish, 1983), the target (chromophore) heats up less if the duration of the laser pulse is less than the thermal relaxation time (TRT) of the chromophore. (TTR is the period of time during which the target temperature, which increased at the moment of the pulse, will decrease to 50% of the initial level) A pulse duration exceeding the TTR will cause unwanted overheating of the tissue. For water-containing skin components, the TTR is about 1 ms. Accordingly, lasers with pulse durations of less than 1 ms are capable of rapidly vaporizing tissue, leaving a very narrow zone of residual thermal necrosis (up to 100 μm).

All modern carbon dioxide lasers use computerized scanners - CPG (Computer Pattern Generator) - to distribute energy evenly onto the skin. The most effective carbon dioxide laser for skin resurfacing is the ultra-pulse laser UltraPulse Encore (Lumenis, USA), which has the best technical characteristics: maximum peak power when exposed to up to 240 W, entering the tissue in a short period of time - up to 1 ms.

Indications for laser skin resurfacing with a CO2 laser: • photoaging of types III–IV according to the Glogau scale (RG Glogau, 1996); • age-related aging of the skin, manifested by wrinkles of varying clinical severity and loss of elasticity; • eyelid skin defects (laser pseudoblepharoplasty is indicated); • actinic and seborrheic keratosis; • gravitational ptosis of the face (non-surgical facial skin tightening is indicated).

Laser skin resurfacing with a CO2 laser is most recommended for patients aged 40–65 years with fair skin and fairly pronounced static wrinkles. For younger patients with initial signs of photoaging, laser ablation with a CO2 laser is not recommended; it is better to use laser technologies based on fractional exposure, which are sufficiently effective for correction in these cases. Patients should be selected with realistic expectations and who do not insist on complete removal of wrinkles. It is not recommended to use carbon dioxide laser resurfacing in the neck, décolleté and dorsum of the hands due to the high risk of scarring.

Patient preparation

It is necessary to pay close attention to the following points: • A history of recurrent herpetic infection (Herpes labialis and facialis) requires treatment with antiviral drugs (Acyclovir, Famvir, Valtrex) 1–2 days before the procedure and continued therapy until complete re-epithelialization (within 7–8 days). • If there is a history of hypertrophic and keloid scars, laser resurfacing deeper than the papillary dermis should be avoided. • If there is significant drooping or severe laxity of the skin of the lower eyelid, it is not recommended to use aggressive laser resurfacing, so as not to provoke the formation of ectropion (inversion of the lower eyelid). • It is imperative to evaluate the allergy history. Local anesthesia is contraindicated in patients with a true lidocaine allergy. • Laser resurfacing should not be performed in psychologically unstable patients, as they will not be able to adequately withstand the full course of rehabilitation measures and thereby provoke the development of adverse complications.

Contraindications for laser skin resurfacing with a CO2 device

Absolute contraindications: • pregnancy, lactation; • active bacterial, viral, fungal infection in the area of ​​laser exposure; • presence of human immunodeficiency virus (HIV), hepatitis C; • systemic connective tissue lesions with damage to the skin and subcutaneous tissue (systemic lupus erythematosus, granuloma annulare, discoid lupus erythematosus, scleroderma, dermatomyositis, etc.); • inflated expectations of the patient, lack of compliance, mutual understanding between the patient and the doctor.

Relative contraindications:

• poor general health of the patient; • taking isotretinoin medications within the previous 6 months; • IV-VI skin phototype according to Fitzpatrick; • patient's rejection of the possibility of postoperative erythema or hyperpigmentation; • significant sagging skin of the eyelids; • excessively thick or thin skin; • tendency to develop keloid and hypertrophic scars.

Result

The effect of the procedure delights patients who tried CO2 Light for the first time. According to their reviews, the skin on the face after laser peeling looks smooth, fresh and perfectly smooth to the touch. In some cases, one procedure will be enough; if indicated, the cosmetologist will prescribe 2-3 sessions at intervals of approximately once a month. The resulting effect will last for a long time, during which the face will look fresh and radiant.

  • Healthy and even complexion and texture;
  • Smooth and elastic skin;
  • Prevention of age-related changes;
  • Alignment of enlarged pores;
  • Normalization of sebum production and water balance in the dermis;
  • Smoothing out small wrinkles;
  • Light skin lifting.

PROTOCOL FOR LASER GRINDING OF FACIAL SKIN USING CO2 LASER

1. Before the procedure 4-6 weeks before laser resurfacing, local therapy is prescribed: • cream containing retinoic acid in a concentration of 0.05–0.1% (0.5–1 g of RetinA or Tretinoin cream, Obagi) , at night; • cream containing 2–4% hydroquinone (0.5–1 g Clear, Obagi) 2 times a day, morning and evening (patients with skin phototype I may not be prescribed hydroquinone); • cream containing 2–4% AHA (0.5–1 g Exfoderm) in the morning; • sunscreen with SPF 30 or higher. Immediately before the procedure, the skin is cleansed (washed) using antibacterial soap. Then the skin is treated with a solution of chlorhexidine bigluconate 0.05%. The peripheral areas of the face should be covered with a damp cloth. To prevent damage to tooth enamel, gauze or special mouth guards soaked in saline solution should be placed under the lips.

Anesthesia• The use of local infiltration anesthesia is not recommended as this may alter the optimal interaction of the laser radiation with the tissue. • The use of regional nerve block in combination with intravenous sedation is considered the most optimal method of anesthesia. When performing laser resurfacing of the entire face, blockade of the following nerves is required: supraorbitalis, supratrochlearis, infraorbitalis, auriculotemporalis, zygomaticofacialis, mentalis and plexus cervicalis. • Intravenous sedation is carried out using propofol (Diprivan) and midazolam (Dormikum). The analgesic component is provided by fentanyl. This type of anesthesia requires the use of special equipment: an anesthesia-respiratory apparatus, an apparatus for obtaining oxygen, a cardiac monitor, a pulse oximeter and is performed by an anesthesiologist. A laryngeal mask airway should be used to ensure a clear airway during intravenous sedation. In some cases (in combination with surgery), endotracheal anesthesia is used.

2. Carbon dioxide laser resurfacing procedure Treatment parameters are set in accordance with the technical features of the laser device and are selected individually for each patient depending on the clinical indications, skin type and condition.

Treatment protocol • Energy density - 3.5–5.0 J/cm2. • The first pass is produced in dense single pulses with minimal edge overlap. • The treated skin is moistened with wipes soaked in saline solution, then the remaining necrotic skin tissue is removed. • The second pass follows the same pattern, but the pulses must be applied at a 90° angle to the first pass. During the second pass, the tightening of the skin is more noticeable. The depth of ablation decreases. The second and subsequent passes can be used to treat specific areas of the skin, for example in areas with severe photodamage or scar deformities.

Treatment scheme: forehead → temporal area → cheeks and chin → eyelids.

To prevent the appearance of a demarcation line, it is necessary to smooth out the boundary between the edges of the treated and untreated skin, making only one pass in this area using low radiation parameters. It is better not to remove the remains of necrotic tissue. The number of passes is determined by the degree of photodamage to the skin: one pass for mild, two for moderate, three for severe photodamage. The end of the procedure is the appearance of a yellow or brown discoloration of the skin, which is a sign of thermal damage, which persists after removing the detritus with a saline soaked cloth. This recommendation should always be followed, even if optimal clinical results are not achieved. As the depth of ablation increases, there is a risk of developing irreversible complications - scars and hypopigmentation. The ablation depth should be limited to the papillary dermis for mild to moderate photodamage or to the upper/middle reticular dermis for severe structural changes and elastosis.

3. Postoperative care There are two ways to manage the wound surface: 1. Open - use of occlusive ointment based on petroleum jelly until complete re-epithelialization occurs. You can also use Dexpanthenol in combination with chlorhexidine, Bepanten Plus cream or methyluracil ointment. Antibacterial ointments should not be used due to the risk of contact dermatitis. 2. Closed - use of semi-occlusive dressings: polyurethane film (Silon II), hydrocolloid (Flexzan) or hydrogel dressing (Vigilon). The advantage of this method of managing the wound surface is faster re-epithelialization of the skin. Disadvantages include an increase in the cost of rehabilitation measures, the risk of infection, and the need for frequent visits to the clinic.

Follow-up care of the patient • The patient must be provided with the opportunity to have constant contact with the attending physician (primarily by telephone). • During the first week, exudation of varying severity and crust formation occurs. Skin care during this period depends on the method of wound management. • Approximately 2–3 weeks after complete epithelialization, light moisturizing creams can be used. • 3-4 weeks after the procedure, it is recommended to re-prescribe hydroquinone and retinoic acid cream. Alpha hydroxy acids should not be used in the early stage of healing until the epidermal layer is completely restored and skin sensitivity is restored. • Patient assessment schedule: 2-3 days, 1 week, 3-4 weeks, 3 months, 6 months and 1 year after the procedure.
