CO2 fractional laser in cosmetic dermatology

portable CO2 fractional laser machine

The best CO2 fractional laser machine is a common cosmetic treatment, commonly used for skin treatment such as mole removal, flat warts, acne pit scars, etc. It can also be used for facial rejuvenation such as wrinkle removal, etc. CO2 laser skin resurfacing machine is a minimally invasive laser treatment technique. Traditional CO2 laser treatment has a long recovery period and greater damage, while CO2 fractional laser, which has both the remarkable effect of ablative treatment and the short recovery period and less damage of non-ablative treatment. Today we will focus on the CO2 laser.

What is a CO2 laser

The CO2 laser, which has been used as a medical laser for decades, works by absorbing the energy of the laser and heating the water in the tissue into water vapour, resulting in vaporisation and exfoliation, with the remaining heat producing coagulation, closure of blood vessels and stimulation of type I and type III collagen renewal.

Applications of the CO2 laser

Because of its early introduction, the CO2 laser is now used in more than just medical aesthetics, for example, in surgery and ophthalmology as a routine treatment, but we will only describe its use in the field of skin aesthetics.

In the field of aesthetics, the portable CO2 fractional laser machine is widely used in cosmetic dermatology as a laser for full epidermal reconstruction. Before the application of fractional technology, the CO2 laser was used as a laser for full epidermal reconstruction, i.e. full face peel, but the Asian skin type is type III-IV and is very prone to inflammatory discolouration, so full face peels were only carried out well in the European and American groups.

Today, fractional technology has matured and Asian doctors are beginning to experiment with more clinical applications of the acne scars co2 fractional laser, with the most current applications being various acne pits. Today, CO2 laser equipment is basically available in both private and public dermatology and aesthetics departments, so it is quite a popular laser procedure.

The main principles of the CO2 laser

1. Epidermal peeling reconstruction

When the energy density and pulse width of the CO2 laser reaches a certain value, one CO2 laser can peel off and vaporise 20um of skin tissue.

2.Stimulation of collagen renewal

If the laser is fired in a scanning fractional manner, a burn zone will be formed in the epidermis consisting of laser action fractions and intervals, and the laser can directly penetrate into the dermis at each point, which will directly vaporize the epidermal tissue at the moment of penetration, thus stimulating collagen production and further initiating a series of biological reactions such as dermal tissue repair and collagen rearrangement.

3. Causes collagen fibre contraction

Collagen fibres will also shrink by approximately one third under the action of the laser, resulting in a tightening effect.

Regarding CO2 fractional laser machine equipment, there are actually many very professional content. This is just the most obvious popular science. I believe that this article will not solve all your questions and concerns. Welcome to actively leave a message in the background. I will collect and organize it. If I can't answer it, I will also ask professional doctors to give professional answers.
