980nm laser yog qhov zoo tshaj plaws nqus spectrum ntawm porphyrin vascular hlwb.Vascular hlwb nqus lub zog laser ntawm 980nm wavelength, solidification tshwm sim, thiab thaum kawg dissipated.Piv nrog rau cov txheej txheem ib txwm muaj, 980nm diode laser tuaj yeem txo qhov liab, hlawv ntawm daim tawv nqaij.Nws kuj muaj feem tsawg dua rau kev ntshai.Txhawm rau kom ncav cuag lub hom phiaj cov ntaub so ntswg kom raug, lub zog laser yog xa los ntawm tus kws tsim qauv tes-thooj.Pab nrog infrared rays 635nm, Nws ua kom lub zog ua kom pom tseeb.
Laser tuaj yeem txhawb kev loj hlob ntawm dermal collagen thaum kho vascular, nce epidermal thickness thiab ntom, kom cov hlab ntsha me tsis raug nthuav tawm, tib lub sijhawm, daim tawv nqaij elasticity thiab ua haujlwm kuj tseem txhim kho.
