On the road of pursuing flawless skin, redness and dullness are the two insurresurable fortresses. Many consumers have tried expensive skin care products, but found that the redness on their faces was still stubborn, and the rough and dull complexion did not improve.

In recent years, the medical and beauty industry has set off a boom of “CO2 laser skin rejuvenation”. Many customers said that after doing it, not only the pores were small, but even the face was whiter. Is this marketing rhetoric, or is it true?

Today, from the perspective of skin physiology, we will deeply analyse the fractional CO2 laser to improve the underlying logic of redness and dullness, and discuss why a high-stability device is the key to effectiveness and safety.

1. CO2 Laser Not Only Removes Scars, But Also Makes Our Skin Brighter

When it comes to CO2 laser, the first thing that many people think of is acne scars. Indeed, it is the gold standard for scar repair. But its ability is much more than that.

1.1 What is CO2 Laser?

This means that it does not peel off the epidermis in a large area like traditional CO2 laser, but through Fractional Mode, it plays countless micro-treatment areas with extremely small diameters (MTZs ). These beams penetrate the epidermis and reach the dermis.

1.2 Understand the Working Principle Of the Fractional CO2 Machine

When the laser goes deep into the dermis, two key actions will occur:

Instantly vaporisation: Instantly vaporising the tissue around wrinkles and scars, directly removes ageing, pigment-containing epidermal cells and vascular walls of lesions.

Thermal solidification and stimulation: The heat around the beam will form a ring thermal coagulation band, and the signal will be transmitted to the Collagen Complexes, starting tissue repair and Collagen Reshaping.

Simply put, it is to force the skin to activate the self-repair mechanism, so as to grow new and healthy skin tissue.

2. In-depth Analysis to Improve the Dullness

“My skin is whiter” usually does not refer to the bleaching of pigments, but refers to the improvement of the permeability and light reflectivity of the skin.

2.1 Peel Off Ageing Keratin and Metabolic Pigmentation

With age and ultraviolet damage, our cuticles will accumulate, causing the skin to look gray. The gasification effect of CO2 laser can accurately peel off this ageing epidermis with old pigments.

When those keratinocytes containing melanin are gasified by the microtherapy area and replaced by new, neatly arranged and clean cells, the reflection of light on the surface of the skin will become uniform and visually white. This kind of whiteness is the embodiment of the skin’s lustre.

2.2 The Collagen Regeneration is the Key

Another reason for dullness is dry skin and messy texture. When the laser stimulates a large amount of collagen in the dermis to be reborn and rearranged, the skin thickness increases and the texture becomes flat.

It’s like a dry rag and a wet sponge – when the skin becomes full from dry, the light penetrates better, not only does it look transparent, but the pores will also shrink due to firmness (Pore Shrinkage), and the overall skin tone is naturally brightened.

3. How to Improve the Redness: Selective Photothermal Effect

Redness is a pain in many sensitive muscles. The key to the reason why CO2 laser can solve this problem is its water absorption characteristics.

3.1 Targeted Absorption: Water is a Colour Base

Although haemoglobin also absorbs lasers, the main target base of CO2 laser (10600nm) is water. The blood in the vascular wall and blood vessels contains a large amount of water.

When laser energy (thanks to the stable energy output ensured by the 1000w high-power power supply) penetrates the skin and is strongly absorbed by the moisture in the blood vessels, the instantaneous high temperature will cause the dilated capillaries to coagulate and necrosis, and then be swallowed and metabolised by human macrophages.

3.2 The Thermal Effect that Reaches the Dermis

The redness is located in the dermis. Ordinary photon skin rejuvenation energy is relatively shallow, and the effect on thick red blood silk is limited. The dot matrix CO2 laser can accurately form a thermal coagulation area in the dermis and directly close the lesion blood vessels. When these messy blood vessels are removed, the redness of the face subsides and the skin tone returns to uniformity, which is also another meaning of even skin tone.

4. Nubway Equipment: The Cornerstone of Determining Effectiveness and Safety

There are so many CO2 machines on the market. Why are some of them effective and recover quickly, while others are prone to scars or colour? It depends on the core parameters of the device.

4.1 Stability of Ultra-long-life Radio Frequency Tube (20,000 Hours)

The fractional uses a radio frequency tube with a life span of 20,000 hours. The radio frequency tube is the core of CO2 laser. The energy of low-quality tubes will decay with the increase of use time, resulting in the operator’s inability to accurately judge the output.

A machine with a radio frequency tube with a lifespan of 20,000 hours can ensure the high consistency of energy output in many years of use. For consumers, this means that the energy of each shot on the face is accurate and sufficient. It will not be ineffective because of insufficient energy, nor will it cause burns due to high and low energy.

4.2 Stability of Non-Polarisation Light and Light Guide Arm

The laser emitted by the fractional array is not polarised and the light-guiding arm is firmly fixed , making it less likely to become inexpensive. The strong light guide arm ensures that the movement of the hand equipment will not cause loss or deviation of energy conduction during the doctor’s operation. This stability is directly translated into the safety of clinical treatment, reducing the risk of strains or excessive burns caused by equipment shaking or uneven light spots.

4.3 Multi-mode integration: one machine for multiple uses

• Fractional mode, gynaecological mode and surgery mode are all in one, multi-purpose machine. This is not only the selling point of the merchant, but also the embodiment of the maturity of technology.
• Fractionalmode: used for facial rejuvenation, acne pits and pores.
• Gynaecological model: used for private rejuvenation, using heat to improve relaxation and dryness.
• Surgical mode: It can be used to remove skin lesions.

The integration of multiple modes proves the degree of refinement of energy control of the device, which can output different wave forms and energy for different parts.

FAQ

Q: How many times do you need to do CO2 laser to improve redness and dullness?

For red blood silk, if it is a relatively shallow capillary dilatation, there will usually be a significant improvement 1-2 times; for dullness and overall skin rejuvenation, it is generally recommended to treat according to the course of treatment, 3 times is a cycle, with an interval of 2-3 months each time. Regarding anti-black (PIH, that is, post-inflammatory pigmentation), this is a risk that East Asians need to pay attention to.

Q: This machine can do both facial and gynaecological work. Will there be a risk of infection with a shared probe?

This is a very good hygiene problem. Although the equipment itself is multi-mode integrated, the treatment hand tools and probes are disposable or undergo strict high-temperature autoclave. In regular medical institutions, facial treatment heads and gynaecological treatment heads are strictly distinguished and individually disinfected and packaged, and will never be cross-used, which can be completely assured.
