Mtundu wa khungu la munthu umadalira chinthu monga melanin. Monga lamulo, pamene thupi limakhalapo, thupi lake limasokonezeka ndipo mabala a pigment a maonekedwe ndi makulidwe osiyanasiyana, kawirikawiri amafiira mtundu, amaonekera pakhungu. Kawirikawiri izi zimawonetsedwa mwa amayi. Kwa iwo kaŵirikaŵiri zimachitika chifukwa cha cholakwika cha metabolism, zodzoladzola zoipa, matenda ena, makamaka achilendo, kukhala ndi dzuwa nthawi yaitali, mimba ndi kulephera kwa mahomoni.

Pachifukwa ichi, mapuloteni amalowa m'malo ano, omwe angapangitse kuti mdimawo usakhalenso wamdima. Komabe, patapita masiku angapo tsamba limatha, ndipo pamalo ake khungu latsopano loyera limawonekera.

Ndiye chipangizo chapadera cha IPL chimaonekera poyera pa ziwalo zenizeni za khungu, nthawi yomweyo kuziwotcha komanso kusakhudza thupi lonse.
Mu mawanga omwe ali ndi khungu, mapuloteni amayamba kugawanika, kuchotsa maselo odwala - omwe ali ndi mitundu yambiri ya nkhumba, ma collagen ndi ma melanin. Maselo akuwonongeka mofulumira kwambiri, pafupipafupi, nthawi yomwe selo likuwonongeka ndi masekondi pafupifupi 0.001.
