Overview of Portable 1927nm fractional thulium laser treatment:

1. 1.The penetration depth of each point increases with the increase of power within a certain range; it can fully penetrate into the superficial and middle layers of the dermis, obtain thermal stimulation, achieve immediate contraction, and a relatively long-lasting collagen contraction and regeneration effect.
2. 2.After focusing, the size of a single point is very small, which can reach 1/5 of the diameter of a CO2 laser spot. The smaller the focus point, the higher the energy density.
3. 3.The energy density of each point is very high, which can easily reach more than 800J/cm2. Therefore, in the treatment of thulium laser, the energy value of each scanning laser point is very small (usually the typical value is 2-4mJ), which can cause heat accumulation and deep dermal temperature rise in a micro environment, protein thermal coagulation, slight thermal denaturation of the epidermis, open the skin absorption channel, and start the skin repair and reconstruction process.
4. There is a momentary tingling and hot pain during the treatment, and the pain comes from the inside out.
5. 4.After treatment, the skin will soon show transient slight redness and swelling. In the first two days, the skin may appear transiently dark and slightly red. This is a normal phenomenon. A small amount of slight scabs may appear, but immediate epidermal damage similar to CO2 laser is very rare.
6. 5.After facial treatment, the skin will be immediately tightened, lifted, whitened, refined, with improved tone and pore tightening effects.
