How much do you know about 1927nm Thulium laser?

Princle:

The working principle of thulium laser is to shrink pores, improve fine lines, and tighten skin by stimulating the production of collagen and inducing collagen contraction. During the penetration process, the hemoglobin in the blood vessels absorbs it more strongly, so it has the effect of coagulating blood and treating red blood filaments and acne (inflammation). It has an excellent blasting effect on superficial melanin, so it is also very effective in treating acne scars and dark skin problems.

Compared with other wavelength:

Thulium laser water molecules absorb between

Non-ablative laser (1440, 1540, 1550, 1565)

and ablative lasers (CO2, ER)

Water absorption:

1550nm(Er:Glass) < 1927nm(Thulium) < 10,600nm(CO2)
