CO2 Laser Tratment 

LONDON

Acne scar treatment with CO2 laser is very common and has been performed for many years in dermatology, using either collimated resurfacing or fractional CO2 laser. The CO2 laser flattens and reduces the overall skin surface, improving the appearance of scars. If the fractional laser technique is used, several treatment sessions are required, usually between 4 and 8. Post-treatment application of exosomes accelerates recovery and improves results (CO2 7)(CO2 8)(CO2 9).

The CO2 laser can also improve scars on the body. It does this using the fractional CO2 technique. This is because the skin on the body has far fewer skin appendages than facial skin, making scar repair much more difficult. The purpose of the fractional CO2 laser is to reduce the size of the scar, and several sessions must be repeated (CO2 10) and (CO2 11).

This is one of the favorite treatments among dermatologists. Fractional or collimated CO2 lasers can be used. The fractional requires several sessions (4 is the most common), while the collimated requires a single session every 10 years. The stronger the laser energy and the treatment, the better the result, but also the longer the recovery time, especially in terms of the duration of redness. The combination with topical Retinol can improve the results (CO2 12) and CO2 13).

Viral warts are skin infections caused by a virus, the papillomavirus, which recurs very easily despite cryotherapy or electrocautery procedures. It appears that with the CO2 laser, recurrence is less frequent, due to the higher temperatures reached by the laser. On the other hand, laser removal of a viral wart is less damaging to the surrounding tissue and leaves fewer marks or scars than traditional procedures (CO2 14) (CO2 15).

The CO2 laser can be used to remove all types of skin lesions. Laser destruction of these lesions appears to be less damaging to the surrounding tissue and leaves fewer marks or scars than traditional procedures.

The CO2 laser can be used to remove various types of skin lesions. Removal of these lesions appears to be less damaging to the surrounding tissue and leaves fewer marks or scars than traditional procedures. Surgical lasers are used to cut and excise while simultaneously producing hemostasis to prevent bleeding. The CO2 laser is also used in surgery to cut the skin more effectively and simultaneously produce coagulation of blood vessels. This is a great advantage because it keeps the surgical field clean and reduces errors. It also shortens surgery time.

One of the best-known surgical applications is blepharoplasty, or eyelid surgery. In this type of surgery, it is important to prevent bleeding. Thanks to the use of the CO2 laser, the surgeon can remove excess fatty tissue while simultaneously coagulating. The procedure is shorter, safer, and more precise thanks to the use of the CO2 laser (CO2 4) (CO2 5).

The fractional CO2 laser is an excellent tool for delivering drugs to the nail when used fractionally. Due mainly to the fact that the nail is a thick keratinized structure that is difficult to penetrate with topical medication, nail pathologies such as Lichen unguium, Psoriasis or fungal infections do not respond well to topical treatment but do respond better when this drug is administered after performing fractional CO2 laser (CO2 1).

The CO2 laser can be operated to open small holes in the skin’s surface to aid drug penetration. This is known as laser-assisted drug delivery and improves the results of applying topical products for skin conditions such as psoriasis (CO2 6).

Treatment of onychomycosis is challenging due to its impact on the nails, the location of the fungus within the nail, and the reported worldwide resistance to antifungals. Light-based technologies and CO2 lasers are treatments that can be used for onychomycosis. The efficacy of photodynamic therapy and fractional CO2 laser, used alone or in combination, has been evaluated for onychomycosis. A prospective, randomized, comparative study of 51 patients with onychomycosis found that treatment with fractional CO2 laser or its combination with photodynamic therapy provided high success rates, good patient satisfaction, and a safety profile (CO2 3).

The CO2 laser is especially convenient for lesions on the female genitals due to its high coagulation capacity and precision.

Fractional CO2 lasers have been reported in numerous published clinical studies to improve dark spots and skin texture associated with photoaging. These treatments are safe and effective for photoaging. The limited and controlled dermal heating of the fractional CO2 laser likely initiates a series of events that result in the normalization of the collagen-genesis/collagenolysis cycle. The introduction of fractional CO2 lasers for photoaging represents a significant advancement over traditional ablative laser resurfacing treatments, which were complicated by prolonged redness, delayed-onset hypopigmentation, and scarring.

Pincer Nail Deformity (PND) is a common toenail disorder characterized by a transverse overcurvature of the nail plate. It can cause severe pain, chronic inflammation, and recurrent infections. Treatment can be performed with carbon dioxide (CO2) laser matricectomy.The result is successful without intraoperative or postoperative complications. Recurrence sometimes occurs 7 months after treatment.

The CO2 laser is widely used in the stomatological field of dentistry. The absorption of CO2 laser light produces various effects such as coagulation, vaporization, and ablation. The main indications in dentistry are pain relief and prevention of recurrence of canker sores and cold sores (minor canker sores, herpes simplex), removal of excess benign and irritating tissue (stimulus fibroma), correction of bands on the lips and tongue, and soft tissue hemostasis. The great advantage of using a CO2 laser is minimal bleeding in the surgical field, which allows for optimal visibility. Furthermore, the CO2 laser offers great patient comfort as primary wound closure with sutures is not necessary (CO2 2).

Another indication for CO2 laser treatment is the treatment of psoriasis or psoriatic nails. In this case, the CO2 laser is used to promote the penetration of the active drug into the psoriasis through fractional mode.In one study, twenty-eight patients with nail psoriasis were assigned to two groups. The first group was treated with a nail matrix injection of methotrexate, while the second group received fractional CO2 laser treatment followed by topical methotrexate application. Treatment was administered 2 weeks apart for 6 sessions. At the end of treatment, both laser-assisted administration and intralesional methotrexate injection resulted in statistically significant improvement in the psoriatic nail. No statistically significant differences were found between the two groups with respect to the overall Nail Psoriasis Severity Index. However, pain and subungual hematoma were significantly less in the laser group than in the injection group (C02 16).
