1927nm Thulium laser beauty equipment
Thulium laser, the full name is thulium yttrium aluminum garnet laser, which belongs to the long-pulse mid-infrared laser. The wavelength of the light is between 1927nm and 1940nm. The depth is between the lower part of the epidermis and the upper part of the dermis. Therefore, the 1927nm thulium laser is the preferred laser device in the mesoderm project.
Features of Thulium laser:
When the thulium laser acts on the skin, the main absorbed target tissue is water, which is not sensitive to skin color. Moreover, the water content of the dermis is higher than that of the epidermis, especially the stratum corneum. Therefore, during the skin treatment process of thulium laser, most of the energy passes through the epidermis without seriously damaging the stratum corneum. The energy is mainly absorbed by the dermis and heats up. The epidermis forms an almost “translucent window” in the transmission of the thulium laser light.
Fractional thulium laser can open the local barrier microchannels of the skin, stimulate blood supply, and has good transdermal absorption capacity, so we can use this feature to introduce corresponding functional products according to the skin condition of customers to achieve Comprehensive beauty effect.
What does thulium laser do?
- Lift and firm skin, treat static wrinkles
- Whitening and blemishes, brightening skin tone
- Shrink pores, control oil
- anti-inflammatory acne
- Shrink eye bags, lift eyelids, dilute dark circles
- stimulate hair growth
Principle of 1927nm thulium laser treatment.
When the thulium laser penetrates the skin, the water in the dermis absorbs strongly, resulting in a thermal effect, and the skin initiates the regeneration and repair mechanism, which stimulates the proliferation of collagen fibers and stimulates the production of more hyaluronic acid to achieve water-locking and rejuvenating skin. Enhances anti-wrinkle and anti-inflammatory effects.
When the thulium laser penetrates the skin, the temperature of melanin will be higher than that of other basic tissues due to the selective absorption of light and heat, and the melanin will be inactivated by heating. Therefore, the critical melanin can be heated and deactivated, and there is an obvious whitening effect after treatment.
When the thulium laser penetrates the skin, the hemoglobin in the blood vessels absorbs it more intensely, so it has the effect of coagulating blood and treating red blood streaks and acne.
Thulium laser can penetrate into the mesoderm of the dermis, stimulate collagen fiber regeneration, and at the same time not excessively damage the epidermis, the damage is small, no scab, almost no downtime, and because the penetration depth of the laser is deep, the heat diffusion effect of the skin is obvious, and it is not easy It can cause burns to the skin, so the thulium laser is also very safe, and there is no downtime trouble, so the customer acceptance is high.
We have found that in practice, the “depth of penetration” and the “depth of treatment” of the laser can be two different things, which often depends on the density of the laser energy.
In the treatment process, because 2940nm has the highest water absorption rate, when it reaches the epidermis, it is greatly absorbed by the water-containing epidermal stratum corneum and dermal papillae, and if the laser energy is higher, it will immediately form exfoliation, vaporization and coking reaction in the epidermis, so we cannot let 2940 erbium laser penetrate into the dermis to form a “thermal coagulation zone” during the treatment process. The absorption coefficient of the 10600 laser is only about 1.5 times higher than the absorption coefficient of the 10600 laser.
The absorption coefficient of 10600 laser is second only to 2940, so it can penetrate the epidermis, and the tissue it mainly absorbs is located in the water of the dermis, so it can be irradiated with high energy more easily, and there is a small peeling, reaching the dermis, and if we continue to increase the energy and the time of irradiation, then there may be bleeding and scorching burns, and the results of vaporization and peeling.
1550/1927 are located in the spectral range of the near infrared and are the two small peaks of water absorption. Comparatively, the absorption of 1927 Thulium laser by water is only 1/6 of CO2, then it may act deeper on the skin than CO2 while avoiding vaporization and scorching reactions, that is, avoiding intense destruction of skin tissues, which leads to inflammatory reactions stimulating melanin activation, within the premise of safe therapeutic energy. Under this premise, 1927 in the way of using, mainly to thermal coagulation, rather than peeling vaporization, then it can be considered a safer kind of infrared laser, so there is a broader application prospect.
I am interested in Thulium laser machine.
