The cosmetic effects of CO2 laser

The CO2 laser skin resurfacing machine is a common cosmetic treatment, commonly used for skin treatments such as mole removal, flat warts, acne pit scars and for facial rejuvenation such as wrinkle reduction, and is a minimally invasive laser treatment technique. Bvlaser is a dermatology CO2 laser machine factory manufacturer, we have portable CO2 fractional laser machine for sale.

Treatment principle of the CO2 laser

The CO2 fractional laser works by using "focal photothermal action" by emitting a matrix of hair-thin laser beams that are evenly spaced in tiny holes that act directly on the dermis. When these tiny laser beams are applied to the surface of the skin. To a certain extent, the cellular tissue beneath the dermis is stimulated, forcing its cells to proliferate and align, thus improving the sunken, sagging face.

The full face CO2 laser resurfacing is a minimally invasive laser, the basic principle of which is based on the thermal effect of the laser heating to burn different layers of the skin and then stimulate the cells, the stimulated cells can activate the body's own repair mechanism, intensify the cell proliferation, so that the skin itself can be thickened while achieving a series of cosmetic effects. The principle is that the water in the tissue absorbs the energy of the laser and is heated to water vapour, resulting in vaporisation and exfoliation, with the remaining heat producing coagulation, sealing the blood vessels and stimulating the renewal of type I and type III collagen.

The cosmetic effects of the CO2 laser

The CO2 fractional laser emits at a wavelength of 10600nm, which itself is an exfoliating fractional laser that also relies mainly on the thermal effect. It heats up the water in the cellular tissue to over 100°C. It penetrates deeper into the skin while acting on the surface, where the peak energy is high but the thermal damage caused is low, as it has a precise irradiation range and does not affect other surrounding cellular tissues outside the irradiated area, and usually heals in 3 to 5 days. Complications such as hyperpigmentation or hypopigmentation are therefore less likely to occur. The 10600nm wavelength also has a coagulation effect, so although there are minimally invasive wounds, there is rarely any bleeding, and it allows the hollows to rebound for a better aesthetic improvement. After all, a major cause of enlarged pores is reduced collagen and damaged collagen fibre network, and the CO2 fractional laser can emit tens of hundreds of tiny laser dots at the same time. It penetrates into the dermal layer of the skin without damaging the skin's integrity.

Frequency of CO2 laser cosmetic treatments

Usually every time you do it, the scar texture and activity will be much better after one CO2 fractional laser treatment than when it was not done, but to achieve a satisfactory state, you need to do it 3-5 times depending on the situation, some special people even need to do it more times, for example, after a local treatment after 2-3 months of repair ability to reach a relatively good state, you do not need to do a second The second treatment is not necessary.

Care after CO2 fractional laser treatment

1. Reduce the inflammatory response and the duration of redness and swelling

A mask containing 2% salicylic acid can be applied immediately to provide an anti-inflammatory and analgesic effect. Wipe clean and apply a cold repair mask, preferably one with simple ingredients, containing only water and collagen, to avoid the risk of allergy and to soothe the redness.

2. Treat allergic reactions promptly

For those with sensitive skin, apply ice packs before and after the mask to assist the LED photodynamic red light to accelerate blood circulation for soothing repair. After the CO2 fractional laser treatment, apply cold gel as a support and barrier for the damaged skin.

As the most classic medical aesthetic procedure, the CO2 fractional laser itself has many advantages, but compared to most medical aesthetics, it still has the potential for side effects after treatment and there are certain safety risks associated with the operation of the laser, so when choosing CO2 fractional laser treatment, you should choose a regular medical institution and an experienced operator.
