Qhov sib txawv tseem ceeb ntawm glycolic acid thiab hyaluronic acid yog tias glycolic acid yog qhov yooj yim tshaj plaws alpha hydroxy acid whereas hyaluronic acid yog tib qho uas tsis yog sulfated glycosaminoglycan. Tsis tas li ntawd, glycolic acid ib txwm tshwm sim hauv qee cov piam thaj-cov qoob loo thaum hyaluronic acid ib txwm tshwm sim hauv tib neeg lub cev.
Ob leeg glycolic acid thiab hyaluronic acid yog cov khoom xyaw hauv ntau yam khoom siv tawv nqaij. Qhov no yog vim hais tias cov tebchaw no tuaj yeem txhim kho qhov zoo ntawm daim tawv nqaij. Tsis tas li ntawd, muaj ntau yam kev siv ntawm cov tshuaj no raws li tau teev tseg hauv qab no.

YGlycolic Acid yog dab tsi?
Glycolic acid yog cov organic compound uas muaj cov tshuaj formula C2H4O3, thiab nws yog qhov yooj yim tshaj plaws alpha hydroxy acid. Qhov no txhais tau tias cov organic molecule no muaj ib pawg carboxylic functional (-COOH) thiab ib pawg hydroxyl (-OH) sib cais los ntawm ib tug carbon atom. Cov tshuaj no tsis muaj xim, tsis muaj ntxhiab thiab soluble hauv dej. Ntxiv mus, nws yog hygroscopic.
Daim duab 01: Tshuaj Structure ntawm Glycolic Acid
Cov molar loj ntawm Glycolic Acid 76 g / mol thaum lub melting point ntawm no compound yog 75 ° C. Txawm li cas los xij, nws tsis muaj qhov kub hnyiab vim nws decomposes ntawm qhov kub siab dua. Qhov tseem ceeb ntawm daim ntawv thov no compound yog nyob rau hauv lub cosmetic kev lag luam. Cov neeg tsim khoom siv cov khoom sib xyaw no ua cov khoom siv hauv cov khoom siv tawv nqaij. Lawv ua cov tshuaj no los ntawm cov tshuaj tiv thaiv ntawm formaldehyde thiab synthesis gas nrog rau cov catalyst vim tias cov tshuaj tiv thaiv no muaj tus nqi qis. Tsis tas li ntawd, cov kua qaub no muaj zog me ntsis dua li acetic acid vim tias nws cov hluav taws xob tshem tawm hluav taws xob (ntawm pawg hydroxyl).
YHyaluronic Acid yog dab tsi?
Hyaluronic acid yog ib qho nyuaj organic molecule uas muaj cov tshuaj formula (C14H21NO11)n. Yog li ntawd, nws poob rau hauv qeb ntawm glycosaminoglycan compounds. Txawm li cas los xij, qhov sib xyaw no yog qhov tshwj xeeb vim nws tsuas yog tsis muaj sulfated glycosaminoglycan. Cov tshuaj no ib txwm tshwm sim hauv tib neeg lub cev. Nws raug faib thoob plaws hauv cov ntaub so ntswg, epithelial, thiab neural.
Daim duab 02: Cov Qauv Tshuaj ntawm Hyaluronic Acid
Ntxiv mus, tsis zoo li lwm cov glycosaminoglycan tebchaw, daim ntawv sib xyaw no hauv cov plasma membrane (lwm cov glycosaminoglycan compounds hauv Golgi apparatus). Muaj ntau qhov tseeb tseem ceeb ntawm qhov sib xyaw no. Xav txog nws daim ntawv thov hauv kev lag luam tshuaj pleev ib ce, nws yog ib qho khoom siv hauv cov khoom siv tawv nqaij. Ntxiv mus, nws yog ib qho tseem ceeb raws li ib tug dermal muab tub lim nyob rau hauv cosmetic phais. Cov neeg tsim khoom tsim hyaluronic acid feem ntau ntawm cov txheej txheem microbial fermentation. Qhov no yog vim tus nqi qis dua thiab tsawg dua ib puag ncig muaj kuab lom. Cov kab mob loj uas lawv siv rau qhov no yog Streptococcus sp. Txawm li cas los xij, Muaj kev txhawj xeeb txog cov txheej txheem no vim tias hom kab mob microbial no yog pathogenic.
Qhov txawv ntawm Glycolic Acid thiab Hyaluronic Acid yog dab tsi?
Glycolic acid yog cov organic compound uas muaj cov tshuaj formula C2H4O3 Nws yog qhov yooj yim tshaj plaws alpha hydroxy acid. Ntxiv mus, nws ib txwm tshwm sim hauv qee cov qab zib-cov qoob loo. Ntawm qhov tod tes, hyaluronic acid yog cov organic molecule complex uas muaj cov tshuaj formula (C14H21NO11.)n. Nws yog tib yam uas tsis yog-sulfated glycosaminoglycan. Tsis tas li ntawd, nws tshwm sim nyob rau hauv tib neeg lub cev thiab faib thoob plaws hauv cov ntaub so ntswg, epithelial, thiab neural.
Summary - Glycolic Acid vs Hyaluronic Acid
Ob leeg glycolic acid thiab hyaluronic acid yog cov khoom xyaw tseem ceeb hauv ntau yam khoom siv tawv nqaij. Qhov sib txawv ntawm glycolic acid thiab hyaluronic acid yog tias glycolic acid yog qhov yooj yim tshaj plaws alpha hydroxy acid whereas hyaluronic acid yog tib yam uas tsis yog-sulfated glycosaminoglycan.
