Qhov sib txawv tseem ceeb ntawm glycolic acid thiab hyaluronic acid thiab retinol yog glycolic acid pab exfoliating cov tawv nqaij tuag, thiab hyaluronic acid pab nyob rau hauv hydrating ntawm daim tawv nqaij, whereas retinol boosts collagen ntau lawm kom txo tau cov kab zoo thiab wrinkles.
Cov khoom siv tawv nqaij yog nrov heev ntawm cov tib neeg vim cov khoom no tuaj yeem pab tswj cov tawv nqaij noj qab haus huv thiab ntxim nyiam. Glycolic acid, hyaluronic acid, thiab retinol yog cov khoom xyaw tseem ceeb hauv kev tsim cov khoom tu tawv nqaij kom haum rau txhua hom tawv nqaij.
YGlycolic Acid yog dab tsi?
Glycolic acid yog cov organic compound uas muaj cov tshuaj formula C2H4O3Nws yog categorized li qhov yooj yim alpha hydroxy acid (AHA). Qhov no txhais tau hais tias qhov sib xyaw no muaj pawg carboxylic ua haujlwm (-COOH) thiab pawg hydroxyl (-OH), uas yog sib cais los ntawm ib qho carbon atom nkaus xwb. Feem ntau, glycolic acid yog cov xim tsis muaj xim, tsis muaj ntxhiab, thiab cov khoom soluble heev hauv dej, thiab nws kuj yog hygroscopic.
Cov molar loj ntawm glycolic acid yog 76 g / mol, thaum nws melting point yog 75 ° C. Tab sis, 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 glycolic acid ua cov khoom muaj nyob 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 nws lub zog rho tawm hluav taws xob (ntawm pawg hydroxyl).
YHyaluronic Acid yog dab tsi?
Hyaluronic acid yog ib qho polymeric organic molecule nrog cov tshuaj formula (C14H21NO11)n Peb tuaj yeem faib nws ua glycosaminoglycan compound. Tsis tas li ntawd, hyaluronic acid yog ib qho tshwj xeeb, organic molecule vim tias nws tsuas yog cov tsis muaj sulfated glycosaminoglycan ntawm lawv. Cov tshuaj no ib txwm tshwm sim hauv tib neeg lub cev. Nws tuaj yeem raug xa mus thoob plaws hauv cov khoom sib txuas, epithelial, thiab cov ntaub so ntswg neural.
Tsis zoo li lwm cov glycosaminoglycan compounds uas tsim nyob rau hauv Golgi apparatus, cov compound no yog tsim nyob rau hauv lub plasma membrane. Hyaluronic acid yog ib yam khoom muaj nyob rau hauv ntau yam khoom siv tu tawv nqaij. Nws kuj tseem muaj txiaj ntsig zoo li dermal muab tub lim hauv kev phais kom zoo nkauj. Cov neeg tsim khoom tsuas yog tsim hyaluronic acid los 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 siv rau kev tsim khoom yog Streptococcus sp. Txawm li cas los xij, muaj kev txhawj xeeb heev txog cov txheej txheem no vim tias cov kab mob microbial no yog cov kab mob.
Raws li qee qhov kev tshawb fawb tshawb fawb, kev txhaj tshuaj hyaluronic acid rau hauv cov pob qij txha osteoarthritic tuaj yeem kho cov viscoelasticity ntawm cov kua dej synovial, txhawb cov kua dej sib koom ua ke, thiab normalize endogenous hyaluronate synthesis, thiab lwm yam.
YRetinol yog dab tsi?
Retinol yog ib hom vitamin uas peb tuaj yeem pom hauv cov khoom noj, thiab nws yog ib qho tseem ceeb raws li kev noj haus ntxiv. Feem ntau, nws raug txheeb xyuas tias yog vitamin A, ib qho roj-soluble vitamin. Thaum txiav txim siab txog kev siv cov vitamin no, nws yog ib qho tseem ceeb hauv cov khoom noj khoom haus, thiab nws tuaj yeem nkag mus rau kev noj tshuaj thiab tiv thaiv vitamin A tsis txaus. Ntxiv mus, tsis muaj vitamin A tuaj yeem ua rau xerophthalmia.
Yog tias peb noj cov tshuaj retinol hauv ib txwm noj, lub cev tuaj yeem zam tau yooj yim, tab sis yog tias koob tshuaj ntau, nws tuaj yeem ua rau lub siab loj, tawv nqaij qhuav, lossis hypervitaminosis A. Tsis tas li ntawd, noj cov tshuaj retinol siab thaum lub sijhawm. cev xeeb tub tuaj yeem ua mob rau tus menyuam. Thaum noj cov vitamin no hauv qhov ncauj, nws tau hloov mus rau hauv retinal thiab retinoic acid. Cov ntaub ntawv no yog cov ntaub ntawv nquag ntawm retinol hauv peb lub cev.
Qhov txawv ntawm Glycolic Acid thiab Hyaluronic Acid thiab Retinol yog dab tsi?
Glycolic acid, hyaluronic acid, thiab retinol yog peb cov khoom xyaw uas siv hauv cov khoom no. Qhov sib txawv tseem ceeb ntawm glycolic acid thiab hyaluronic acid thiab retinol yog glycolic acid pab exfoliating cov tawv nqaij tuag hlwb, thiab hyaluronic acid pab nyob rau hauv hydrating ntawm daim tawv nqaij, whereas retinol boosts collagen ntau lawm los txo cov kab zoo thiab wrinkles. Txawm li cas los xij, kev siv tsis raug ntawm glycolic acid tuaj yeem ua rau tawv nqaij khaus thiab puas, thaum hyaluronic acid tuaj yeem ua rau tawv nqaij qhuav. Retinol, ntawm qhov tod tes, tuaj yeem ua rau ziab, flaking, shedding, redness, thiab irritation.
Cov hauv qab no qhia txog qhov sib txawv ntawm glycolic acid thiab hyaluronic acid thiab retinol hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary - Glycolic Acid vs Hyaluronic Acid vs Retinol
Qhov sib txawv tseem ceeb ntawm glycolic acid thiab hyaluronic acid thiab retinol yog glycolic acid pab exfoliating cov tawv nqaij tuag, thiab hyaluronic acid pab nyob rau hauv hydrating ntawm daim tawv nqaij, whereas retinol boosts collagen ntau lawm kom txo tau cov kab zoo thiab wrinkles.
