Qhov no tsis muaj xim, tsis muaj ntxhiab, thiab hygroscopic crystalline khoom yog soluble hauv dej. Nws yog siv rau hauv ntau yam khoom tu tawv nqaij.
YPuas glycerin thiab glycolic acid tib yam?
Glycolic acid muaj nyob rau hauv txiv hmab txiv ntoo, beets, lwm yam txiv hmab txiv ntoo thiab qab zib thiab yog nonflammable. Glycerin pom muaj nyob hauv cov rog thiab muab rho tawm los ntawm cov rog uas koom nrog hauv kev tsim cov xab npum.
YPuas retinol thiab glycolic acid ua tib yam?
Raws Dr. Koo, retinol thiab glycolic (nrog rau lwm yam AHAs) muaj cov haujlwm sib txawv. Thaum glycolic zoo tshem tawm cov khib nyiab ntawm daim tawv nqaij, retinol nkoos cell regeneration lizoo li tsim cov collagen thiab elastin, uas txo cov tsos ntawm wrinkles.
Koj ua li cas hauv tsev glycolic acid?
Kauj Ruam 1: Muab cov cane qab zib tso rau hauv lub tais sib tov. Kauj Ruam 2: Ncuav rau hauv cov kua txiv qaub thiab do kom txog thaum sib xyaw ua kemuab tshuaj txhuam. Cov kua txiv qaub muaj citric acid, lwm hom alpha hydroxy acid, yog li sib xyaw nrog cov suab thaj ua rau lub tev zoo dua. Aws!
Qhov twg zoo dua glycolic lossis salicylic acid?
Glycolic acid yog ib qho exfoliant zoo, txhais tau tias nws tuaj yeem tshem tawm cov cell tuag. Nws yog qhov tsim nyog los txo qis hyperpigmentation, kab zoo, thiab cov tawv nqaij tsis sib xws.
