Comparison of 1940nm Thulium Laser and 10600nm CO2 Fractional Laser in Cosmetic Applications

In the field of cosmetics, the 1940nm thulium laser and the 10600nm CO2 fractional laser are two highly regarded technologies. They each possess unique technical principles, operational modes, treatment effects, and potential impacts on the skin, along with significant differences in pricing. Below is a detailed comparison of these two laser technologies in cosmetic applications.

Technical Principle Comparison

1940nm Thulium Laser:
The 1940nm thulium laser is a high-energy laser device whose working principle is based on the characteristics of the thulium element, producing laser light through the transfer of excitation energy levels. In the field of cosmetics, the 1940nm thulium laser is primarily used for skin ablation, effectively decomposing subcutaneous melanin and aged melanin abnormalities, increasing skin elasticity, and improving fine lines. The ablation effect of the thulium laser is significant and particularly effective in decomposing subcutaneous melanin.

10600nm CO2 Fractional Laser
The 10600nm CO2 fractional laser is a gas laser whose action principle is fractional photothermolysis. Through the focused photothermal principle of the laser, it produces an array of micro-beams that act on the skin, especially the dermis, thereby promoting the production of dermal collagen and the rearrangement of collagen fibres. This treatment method can create multiple three-dimensional columnar micro-injury structures, with each micro-injury area surrounded by uninjured normal tissue, prompting the skin to initiate repair processes, achieving tightening, rejuvenation, and freckle removal effects.

Operational Mode Comparison

1940nm Thulium Laser:
In the field of cosmetics, the 1940nm thulium laser typically operates in pulsed or continuous wave mode. In pulsed mode, the 1940nm thulium laser can perform precise cutting and ablation, such as removing skin surface imperfections. In continuous wave mode, it is used for faster hemostasis and cutting, such as addressing deep skin issues. The beam diameter of the 1940nm thulium laser is small, featuring high quality and a small diameter, allowing it to be used in conjunction with soft scopes to complete some delicate surgical operations.

10600nm CO2 Fractional Laser:
The operational mode of the 10600nm CO2 fractional laser is primarily fractional, utilizing laser scanning and superpulse functions to perform delicate micro-injuries on the skin. This fractional operational mode ensures that the diameter of the laser beam (light spot) is less than 500 micrometres, and the laser beams are regularly arranged in a fractional pattern, only targeting the lesion area of the skin for minimally invasive treatment without affecting other normal skin tissue.

Treatment Effect Comparison

1940nm Thulium Laser:
In the field of cosmetics, the 1940nm thulium laser is primarily used for freckle removal, acne treatment, removal of red blood silk, and improvement of fine lines. Its ablation effect is significant, effectively removing imperfections on the skin surface, making the skin smoother and finer. Additionally, the 1940nm thulium laser can increase skin elasticity and improve uneven skin tone issues.

10600nm CO2 Fractional Laser:
The application of the 10600nm CO2 fractional laser in the field of cosmetics is more extensive, primarily used for removing acne scars, pigmentation, wrinkles, and skin roughness. By stimulating collagen proliferation and rearrangement, the 10600nm CO2 fractional laser can significantly improve skin texture, making the skin firmer and smoother. Furthermore, the 10600nm CO2 fractional laser promotes epidermal regeneration and tissue repair, restoring skin health within a short period.

Skin Side Effects Comparison

1940nm Thulium Laser:
The damage to skin tissue caused by the 1940nm thulium laser is relatively small. However, due to its significant ablation effect, improper operation or inadequate postoperative care may lead to skin burns, pigmentation, or hyperpigmentation. Therefore, when using the 1940nm thulium laser for cosmetic treatment, it is necessary to strictly control the laser energy and exposure time and to properly perform postoperative sunscreen and skin care.

10600nm CO2 Fractional Laser:
During treatment, the 10600nm CO2 fractional laser may cause some traumatic effects on the skin, such as temporary erythema, oedema, pain, and pigmentation. These side effects usually gradually subside within a few days after treatment, but if the skin is sensitive or the operation is improper, more severe skin reactions may occur. Therefore, when using the 10600nm CO2 fractional laser for cosmetic treatment, it is necessary to choose an experienced doctor for the operation and follow medical advice for postoperative care.

Price Comparison

1940nm Thulium Laser:
The price of 1940nm thulium laser applications in the field of cosmetics varies depending on the treatment area and hospital grade. Generally, the price of the 1940nm thulium laser is relatively high, but the specific price also depends on the patient’s specific situation and the hospital’s charging standards. Due to its significant ablation effect and remarkable treatment results, the 1940nm thulium laser is favoured in some high-end beauty institutions and hospitals.

10600nm CO2 Fractional Laser:
The price range of the 10600nm CO2 fractional laser is relatively wide, ranging from a few thousand to tens of thousands of yuan. The price is influenced by factors such as the size of the treatment area, the number of treatments, the hospital grade, and the doctor’s experience. When choosing the 10600nm CO2 fractional laser for cosmetic treatment, patients should select based on their conditions and financial abilities, while ensuring they choose a formal medical institution and an experienced doctor for the operation.

In summary, the 1940nm thulium laser and 10600nm CO2 fractional laser each have their unique application value in the field of cosmetics. When choosing, patients should select based on their conditions and medical advice to ensure treatment effectiveness and safety. Additionally, when using these two laser technologies for cosmetic treatment, it is necessary to properly perform postoperative care and sunscreen to reduce potential risks and side effects.
