ʻO ka laser 980nm ka mea kūpono loa o ka absorption spectrum o porphyrin vascular cell.Hoʻopaʻa ʻia nā cell vascular i ka laser ikaika nui o 980nm hawewe lōʻihi, paʻa ka paʻa ʻana, a hoʻopau hope.Ke hoʻohālikelike ʻia me ke ʻano kuʻuna, hiki i ka laser diode 980nm ke hōʻemi i ka ʻulaʻula, ke ahi o ka ʻili.He liʻiliʻi ka manawa e makaʻu ai.No ka hoʻokō pololei ʻana i ka ʻiʻo i manaʻo ʻia, hāʻawi ʻia ka ikehu laser e kahi ʻāpana lima hoʻolālā ʻoihana.Kōkua me ka infrared ray 635nm, hiki iā ia ke nānā pono i ka ikehu.
Hiki i ka laser ke hoʻoulu i ka ulu ʻana o ka collagen dermal ʻoiai ka mālama ʻana i ka vascular, hoʻonui i ka mānoanoa o ka epidermal a me ka nui, i ʻole e ʻike hou ʻia nā kīʻaha koko liʻiliʻi, i ka manawa like, e hoʻonui nui ʻia ka elasticity a me ke kūpaʻa o ka ʻili.
