I-Zn-PCA
I-Zinc Pyrrolidone Carboxylate Zinc PCA (PCA-Zn) iyi-ion ye-zinc lapho i-sodium ion ishintshaniswa khona ukuze kwenziwe isenzo se-bacteriostatic, kuyilapho inikeza isenzo sokuswakama kanye nezakhiwo ezinhle kakhulu ze-bacteriostatic esikhumbeni.
Inani elikhulu locwaningo lwesayensi lubonise ukuthi i-zinc inganciphisa ukugcinwa ngokweqile kwe-sebum ngokuvimbela i-5-a reductase. Ukwengezwa kwe-zinc esikhumbeni kusiza ukugcina umzimba ojwayelekile wesikhumba, ngoba ukuhlanganiswa kwe-DNA, ukuhlukaniswa kwamaseli, ukuhlanganiswa kwamaprotheni kanye nomsebenzi wama-enzyme ahlukahlukene ezicutshini zomuntu azihlukaniseki ku-zinc.
