xov xwm

Hyaluronic acid yog ib tug loj molecular polysaccharide muab rho tawm los ntawm bovine vitreous lom zem los ntawm Columbia University ophthalmology professors Meyer thiab Palmer nyob rau hauv 1934. Nws cov kua aqueous yog pob tshab thiab glassy. Tom qab ntawd, nws tau pom tias hyaluronic acid yog ib qho ntawm cov khoom tseem ceeb ntawm tib neeg extracellular matrix thiab intercellular matrix, nrog rau cov muab tub lim ntawm cov hlwb, ua lub luag haujlwm tseem ceeb hauv morphology, qauv, thiab kev ua haujlwm ntawm daim tawv nqaij. Kev laus, wrinkles, thiab sagging ntawm tib neeg lub cev yog ze ze rau qhov txo qis hauv hyaluronic acid cov ntsiab lus hauv daim tawv nqaij.

Raws li kev hais lus, hyaluronic acid yog condensation ntawm ob lub qabzib derivatives, thiab los ntawm kev rov ua dua cov qauv no, nws dhau los ua hyaluronic acid. Qhov no kuj zoo ib yam li cov qauv ntawm feem ntau polysaccharides, yog li ntawd sodium hyaluronatemuaj cov haujlwm zoo ib yam li feem ntau polysaccharides - moisturizing.

Tab sishyaluronic acidtsis ruaj khov. Feem ntau hais lus, hyaluronic acid muaj nyob rau hauv nws daim ntawv sodium ntsev. Raws li qhov sib txawv molecular hnyav, hyaluronic acid tuaj yeem muab faib ua qhov hnyav molecular, nruab nrab qhov hnyav molecular, qis molecular hnyav, thiab oligomeric hyaluronic acid. Tshwj xeeb, txhua qhov chaw tsim khoom muaj kev faib tawm zoo sib xws ntawm qhov hnyav molecular ntawm sodium hyaluronate.UNILONGyog lub chaw tsim khoom ntawm sodium hyaluronate, suav nrog qib tshuaj pleev ib ce, qib zaub mov, qib tshuaj sodium hyaluronate thiab qee qhovsodium hyaluronatederivatives. UNILONG faib cov sodium hyaluronate raws li hauv qab no:

◆High molecular hnyav hyaluronic acid: Hyaluronic acid muaj qhov hnyav molecular siab tshaj 1500KDa, uas tuaj yeem tsim cov yeeb yaj kiab ua pa rau ntawm daim tawv nqaij, xauv rau hauv cov dej noo ntawm daim tawv nqaij, tiv thaiv cov dej evaporation, thiab muab cov dej noo mus ntev. Tab sis nws muaj kev nkag mus tsis zoo thiab yuav tsis nqus los ntawm daim tawv nqaij.

◆ Qhov nruab nrab molecular hnyav hyaluronic acid: Hyaluronic acid muaj qhov hnyav molecular ntawm 800KDa thiab 1500KDa thiab tseem tuaj yeem tsim cov yeeb yaj kiab ua pa rau ntawm daim tawv nqaij, xauv hauv cov dej noo thiab ua kom tawv nqaij.

◆ Tsawg molecular hnyav hyaluronic acid: Hyaluronic acid muaj qhov hnyav molecular ntawm 10KDa thiab 800KDa thiab tuaj yeem nkag mus rau hauv dermis txheej ntawm daim tawv nqaij. Nws plays lub luag hauj lwm nyob rau hauv daim tawv nqaij, xauv nyob rau hauv noo noo, txhawb cov tawv nqaij metabolism, thiab ua rau daim tawv nqaij moist, du, ilv, mos, thiab elastic. Lub peev xwm los tiv thaiv dej evaporation tsis zoo.

◆ Oligo hyaluronic acid: Hyaluronic acid molecules nrog qhov hnyav ntawm molecular tsawg dua 10KDa, piv txwv li tsawg dua 50 monosaccharide cov qauv thiab cov txheej txheem ntawm polymerization tsawg dua 25, tuaj yeem nkag mus tob rau hauv cov txheej txheem dermis thiab ua kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig moisturizing. Tsis zoo li cov hyaluronic acid molecules zoo tib yam uas ua kom cov dej noo nyob rau saum npoo ntawm daim tawv nqaij, lawv muaj lub sijhawm ntev moisturizing, cov teebmeem zoo, siv sijhawm ntev, los tiv thaiv kev laus, thiab cov teebmeem tshem tawm.

Qee cov hyaluronic acids tuaj yeem raug hloov kho cov qauv (acetylation, thiab lwm yam) txhawm rau ua kom tawv nqaij zoo dua. Ordinary hyaluronic acids yog dej-soluble, tab sis lawv affinity rau daim tawv nqaij tsis zoo txaus. Tom qab kev hloov kho, lawv tuaj yeem ua tau zoo rau ntawm daim tawv nqaij.

Yog tias koj muaj lus nug lossis xav tau txog sodium hyaluronate, thov koj xav tiv taujhu rau Unilongthaum twg los tau.
