Sodium hyaluronate yog sodium ntsev daim ntawv ntawm hyaluronic acid, uas tseem hu ua hyaluronic acid, abbreviated li HA, thiab feem ntau hu ua hyaluronic acid.
Raws li qhov hnyav molecular, hyaluronic acid tuaj yeem muab faib ua plaub pawg: siab molecular hnyav hyaluronic acid, nruab nrab molecular hnyav hyaluronic acid, qis molecular hnyav hyaluronic acid thiab oligomeric hyaluronic acid. Nws tau lees paub tias yog qhov zoo tshaj plaws moisturizing muaj hnub no thiab yog dav siv hauv tshuaj pleev ib ce. Sodium hyaluronate moisturize li cas?
1. Nkag siab txog Sodium Hyaluronate
Feem ntau siv hauv kev lag luam tshuaj pleev ib ce yog sodium hyaluronate, uas yog sodium ntsev ntawm hyaluronic acid. Tsis muaj qhov sib txawv ntawm cov khoom ntawm hyaluronic acid thiab hyaluronic acid, thiab lawv raug hu ua hyaluronic acid.
Los ntawm txoj kev xav ntawm cov qauv tshuaj, hyaluronic acid yog lub siab molecular hnyav polysaccharide compound tsim los ntawm polymerization ntawm ob monosaccharides, uas yog D-glucuronic acid (sab laug ib nrab ntawm cov duab saum toj no) thiab N-acetylglucosamine (sab xis ib nrab ntawm daim duab saum toj no). Ob lub monosaccharides teb rau tsim ib qho kev ruaj khov disaccharide, thiab tom qab ntawd cov disaccharide units tau rov ua dua los ua hyaluronic acid.
2. Sodium Hyaluronate Moisturize li cas?
Txij li thaum muaj ntau pawg hydrophilic (tshwj xeeb tshaj yog hydroxyl-OH) nyob rau saum npoo ntawm hyaluronic acid molecules, nws tuaj yeem khi ntau cov dej molecules los ntawm hydrogen bonds, ua si lub luag hauj lwm zoo heev nqus dej, thiab theoretical water retention value yog. 500ml / g.Hyaluronic acid yog faib nyob rau hauv dermis nyob rau hauv ntau qhov ntau, ua si lub luag hauj lwm ntawm "dej reservoir", tiv thaiv daim tawv nqaij los ntawm desquamation, nruj, qhuav kab thiab lwm yam tshwm sim vim txo cov ntsiab lus ntawm cov dej. Yog li, hyaluronic acid tuaj yeem tiv thaiv thiab txhim kho wrinkles thiab ncua kev laus.
Lwm qhov tseem ceeb ntawm daim tawv nqaij laus yog kev so, thiab hyaluronic acid kuj ua lub luag haujlwm tseem ceeb hauv qhov no. Nws cov glycosidic daim ntawv cog lus yog qhov ruaj khov thiab ruaj khov, thiab nws tuaj yeem tsim cov ntaub so ntswg sib txuas hauv cov kua dej, muab cov ntaub so ntswg zoo elasticity thiab siab ua haujlwm. Hauv kev kho mob kev zoo nkauj, kev txhaj tshuaj ntawm hyaluronic acid kuj tuaj yeem sau thiab txhim kho cov caws pliav thiab kev nyuaj siab ntawm daim tawv nqaij.
3. Nws Puas Muaj Lwm Yam Uas Ntxiv Ntxiv Moisturizing?
Ntxiv nrog rau nws lub npe hu ua moisturizing, firming thiab filling functions, hyaluronic acid kuj plays lub luag hauj lwm tseem ceeb tshaj li ib tug extracellular matrix, tswj kev sib cuam tshuam ntawm cov hlwb. Hyaluronic acid yog tsim los ntawm cov hlwb xws li fibroblasts, thiab tom qab ntawd tawm tawm sab nraud ntawm lub hlwb, uas cuam tshuam rau kev ua haujlwm ntawm cov hlwb, xws li txhawb kev tsim kho epithelial thiab kho qhov txhab, txhawb kev ua haujlwm phagocytic ntawm granulocytes, tswj cov lus teb inflammatory, thiab tiv thaiv cov pa oxygen dawb. radicals.
Tsis tas li ntawd, hyaluronic acid kuj tuaj yeem noj hauv qhov ncauj, raws li qhov tseeb tias kev zom thiab nqus ntawm hyaluronic acid tuaj yeem ua rau kom cov synthesis ntawm hyaluronic acid hauv daim tawv nqaij thiab lwm yam ntaub so ntswg. Raws li txoj cai, cov tshuaj pleev ib ce hyaluronic acid tsuas yog ua rau ntawm daim tawv nqaij uas lawv tau thov, thaum lub qhov ncauj hyaluronic acid muaj cov txiaj ntsig zoo thiab tuaj yeem kov yeej qhov tsis zoo uas hyaluronic acid tsis yooj yim nqus los ntawm daim tawv nqaij.
Nws feem ntau ntseeg tias hyaluronic acid muaj qhov hnyav molecular thiab tsis tuaj yeem nkag mus rau ntawm daim tawv nqaij. Yog li cov kws tshawb fawb racked lawv lub hlwb los txhim kho nws thiab tsim cov molecule hyaluronic acid los yog cross-linked hyaluronic acid. Lub npe hu ua me me molecule hyaluronic acid yog hais txog ib qho molecule uas tus naj npawb ntawm cov disaccharide rov ua dua tsis tshaj 1000 thiab qhov hnyav molecular tsawg dua 1 × 106. Hyaluronic acid kuj tuaj yeem degraded los ntawm enzymes thiab tom qab ntawd tshwj xeeb ua tiav los ua oligomeric hyaluronic acid. Nws qhov hnyav molecular me dua thiab tuaj yeem nqus tau los ntawm daim tawv nqaij, ua rau muaj kev cuam tshuam uas cov pa hyaluronic acid tsis tuaj yeem ua tiav.
Ntxiv rau,Kev sib txuas ntawm cov tshuaj tiv thaiv ntawm hyaluronic acid macromolecules tuaj yeem ua tiav los ntawm cov tshuaj siv tshuaj, tig ob-dimensional linear molecules rau hauv peb-dimensional spatial network qauv.Lub cross-linked hyaluronic acid polymer tau txais nyob rau hauv txoj kev no tuaj yeem nyob ntev dua hauv lub cev thaum khaws nws cov txiaj ntsig qub. Nws muaj cov ntawv thov tseem ceeb hauv kev kho kom zoo nkauj yas phais fillers, pob txha thiab kev sib koom ua ke, cov khoom tiv thaiv adhesion, cov khoom hemostatic, thiab lwm yam.
4. Cov lus xaus
Hyaluronic acid yog ib yam khoom muaj nyob rau hauv tib neeg cov ntaub so ntswg. Nws muaj kev nyab xeeb heev raws li cov khoom siv tshuaj pleev ib ce rau kev siv sab nraud thiab cov khoom noj tshwj xeeb rau kev siv qhov ncauj. Cov concentration rau kev siv sab nraud feem ntau yog 0.05%-0.15%. Txawm li cas los xij, tej zaum yuav muaj contraindications thiab tsis zoo tshwm sim hauv kev txhaj tshuaj filling, thiab nws yog contraindicated rau cov neeg uas tsis haum rau hyaluronic acid.
