1. Ubushuhe: Indwara ntoya ya moleki ifite amazi menshi, kuko ikubiyemo ibinyuranye na genes eshatu zamazi (amino, hydroxyl) ku buso bwa molekili, irashobora gushishimura amazi ku ruhu hejuru.

2. Intungamubiri: Amariti mato ya molecular arashobora guhuza na epithelial tissue yihuta binyuze muri stratum corneum kugirango atezimbere uruhu kandi ukomeze uruhu ruhuze.

3. Kurwanya inketi: Gukora molekolar ntoya birashobora kwinjira muri dermis mu buryo butaziguye mu buryo butaziguye, ongera uhindure uruhu rwa Frogen, ongera uhindure uruhu rwa fibre, kandi uruhu rwo kugarura uruhu rworoshye ku ruhu no kurwanya inketi.

4. Uruhu rwuruhu: ibara ryuruhu rwabantu rigenwa ni Melanin muri selile. Indwara ntoya ya molesuland ifite ibinyabuzima byoherejwe mu buryo bwo kugabanya umubare wa Melanin. Amashanyarazi mato maremare afite imikorere yo kwera uruhu na elastique.

5. Gusana uruhu: Imyitozo ntoya ya coleguland irashobora kwinjira munsi yuruhu, hanyuma usangire selile zamaganye, kandi zisukuye

6. Isuku Chloasma: Yagaragaye nubushakashatsi ku barwayi 100 hamwe na chloasma, ufata molekile ntoya, agace ka chloasma kagabanutseho 4.75±200.25PX2, Ibara ryabaye ryoroshye, kandi ikarita y'amabara yagabanutseho 0.35±Dogere 0.38 ugereranije. 27 Imanza zari zifite akamaro, kandi igipimo cyiza cyane cyari 54.00%. Aya makuru yerekana ko molecule ntoya ishobora gukuramo chloasma. Muri icyo gihe, mugihe cyo gufata peleclar ntoya, ibimenyetso byumunaniro, kurakara no kudasinzira byateye imbere.
