Dab tsiDos esPolyglutamic acidHmoovua rauSkoj?
Thaum twg lub ntsiab lus ntawm hydrating thiab moisturizing tuaj, thawj yam uas los rau hauv siab rau cov neeg feem coob yog hyaluronic acid, squalane, thiab allantoin. Niaj hnub no, cia peb paub lwm cov khoom xyaw kom zoo nkauj uas tseem muaj cov txiaj ntsig zoo ntawm kev saib xyuas tawv nqaij, thiab qhov ntawd yogpolyglutamic acid. Los ntawm tsab xov xwm no, cia peb delve tob rau hauv lub luag haujlwm ntawm polyglutamic acid hauv kev tu tawv nqaij.
1.Cov lus qhia luv luv ntawm polyglutamic acid hmoov
Polyglutamic acid ( -PGA) yog cov dej- cov khoom siv roj ntsha uas muaj kuab lom tau npaj los ntawm microbial fermentation, featuring biodegradability thiab non- toxicity, nrog rau qhov hnyav molecular ntau ntawm 5,000 txog 2,000,000 daltons. Nws cov mis molecular yog L-Glu-(L-Glu)n-L-Glu, tsim los ntawm L-glutamic acid txuas los ntawm -amide bonds. Raws li daim ntawv thov, nws tuaj yeem muab faib ua ntau hom molecular hnyav (piv txwv li, qhov hnyav molecular ntawm qib tshuaj pleev ib ce feem ntau yog 70,000-110,000 daltons).

2.Dab tsi uaPolyglutamic acidua rau tawv nqaij?
Cov txiaj ntsig ntawm polyglutamic acid yog txhua yam - puag ncig thiab ntau - txheej, thiab nws tshwj xeeb tshaj yog muaj npe nrov rau nws qhov ua tau zoo moisturizing.
1. Tsis zoo li moisturizing thiab tawv nqaij -nourishing teebmeem
Qhov no yog lub peev xwm zoo tshaj plaws ntawm polyglutamic acid, uas tuaj yeem hu ua "moisturizing superstar".
Super muaj zog tuav lub peev xwm
(1) Nws cov qauv molecular muaj ntau ntawm hydrophilic carboxyl pawg, ua kom nws sib txuas ntau cov dej molecules deb tshaj nws qhov hnyav los ntawm hydrogen bonds. Cov ntaub ntawv theoretical qhia tau hais tias 1 gram ntawm polyglutamic acid tuaj yeem kaw txog li 5,000 grams dej, ib daim duab ntau dua li ntawm hyaluronic acid.
(2) Nws tuaj yeem tsis tsuas yog ntes dej xwb tab sis kuj tiv thaiv nws cov evaporation thiab poob, ua kom muaj cua moisturizing zaj duab xis rau ntawm daim tawv nqaij thiab khov kho cov dej noo hauv stratum corneum.
Synergy thiab Sib piv nrog Hyaluronic acid:
(1)Synergistic nyhuv:Polyglutamic acid thiab hyaluronic acid yog ib khub zoo heev. Polyglutamic acid tuaj yeem ua raws li "cov ntaub thaiv npog", txo cov degradation ntawm hyaluronic acid thiab ua kom nws cov nyhuv moisturizing. Nyob rau tib lub sijhawm, nws tseem tuaj yeem txhawb nqa cov tawv nqaij tus kheej synthesis ntawm hyaluronic acid, txhim kho daim tawv nqaij kom muaj peev xwm tuav tau ntawm sab hauv.
(2) Qhov txawv thiab qhov zoo:
1) Molecular hnyav tis: Polyglutamic acid feem ntau muaj ntau yam kev xaiv yuag molecular, thiab sib txawv molecular hnyav txhua tus ua lawv lub luag haujlwm.
2) Cov yeeb yaj kiab zoo dua- tsim cov cuab yeej: Cov yeeb yaj kiab moisturizing tsim los ntawm polyglutamic acid yog cov sib xws thiab smoother, muab cov tawv nqaij zoo.
3) Ntau "ntse" moisturizing: Nws tuaj yeem hloov kho nws cov dej hauv lub xeev raws li kev hloov pauv ntawm ib puag ncig cov av noo, tswj kom muaj dej noo zoo txawm tias nyob hauv qhov chaw qhuav.
2. Txhawb kev kho ntawm daim tawv nqaij barrier
Cov tawv nqaij noj qab nyob zoo yog lub hauv paus ntawm daim tawv nqaij zoo nkauj. Polyglutamic acid tuaj yeem muab qhov zoo tshaj plaws hydration ib puag ncig rau keratinocytes los ntawm nws cov khoom moisturizing zoo, yog li txhawb kev sib txawv thiab cov metabolism ntawm keratinocytes.
Thaum cov tawv nqaij barrier puas lawm, kev siv cov polyglutamic acid tuaj yeem pab rov qab muaj kev ncaj ncees thiab kev sib koom ua ke ntawm stratum corneum, txo cov dej transdermal, thiab yog li txhim kho daim tawv nqaij ua haujlwm thiab kev noj qab haus huv.
3. Soothing thiab tiv thaiv -inflammatory
Polyglutamic acid muaj cov nyhuv soothing ntawm cov tawv nqaij rhiab, liab lossis khaus.
Cov txheej txheem yog nyob rau hauv ntxiv dag zog rau daim tawv nqaij barrier kom txo tau cov ntxeem tau ntawm lwm irritants xws li pa phem thiab allergens. Lub caij no, qee qhov kev tshawb fawb tau taw qhia tias nws tuaj yeem txo cov kev mob tshwm sim los ntawm kev tswj hwm cov haujlwm ntawm lub cev tiv thaiv kab mob.
4. Brighten daim tawv nqaij thiab txhim kho dullness
Inhibit tyrosinase kev ua haujlwm:Tyrosinase yog ib qho enzyme tseem ceeb hauv cov txheej txheem ntawm melanin synthesis. Cov kev tshawb fawb tau pom tias polyglutamic acid tuaj yeem tsis yog -kev sib tw inhibit qhov kev ua ntawm cov enzyme no, yog li txo qis melanin los ntawm qhov chaw.
Multi-dimensional Brightening:Vim nws lub peev xwm moisturizing muaj zog, nws tuaj yeem ua rau cov stratum corneum nrog cov dej noo thiab ua kom zoo zoo ntawm cov hlwb, yog li tam sim ntawd txhim kho daim tawv nqaij cov luster thiab pob tshab, ua tiav cov nyhuv "tuaj yeem ci ntsa iab". Qhov no, ua ke nrog kev tawm tsam ntawm melanin los ntawm qhov chaw, ua tiav ob qho tib si luv - lub sij hawm thiab ntev - lub sij hawm brightening los.
5. Anti-aging thiab smoothing wrinkles
Instant filling nyhuv:Siab -molecular- hnyav polyglutamic acid tuaj yeem tsim ib zaj duab xis du ntawm daim tawv nqaij. Los ntawm optical diffraction, nws instantly sau cov kab zoo qhuav thiab wrinkles, ua rau daim tawv nqaij smoother. Qhov no yog lub cev tam sim ntawd los tiv thaiv -wrinkle effect.
Ntev -lub sij hawm tiv thaiv -aging:
1)Txhawb kev ua haujlwm fibroblast:Fibroblasts yog cov "tsim" lub luag haujlwm rau kev tsim cov collagen, elastin thiab hyaluronic acid. Polyglutamic acid tuaj yeem txhawb kev loj hlob ntawm fibroblasts, yog li ua rau cov ntsiab lus ntawm collagen nyob rau hauv daim tawv nqaij, txhim kho elasticity thiab firmness, thiab hauv paus combating sagging thiab wrinkles.
2)Qhov kawg moisturizing:Dryness yog thawj qhov ua rau cov kab zoo. Los ntawm kev tuav cov stratum corneum nyob rau hauv ib qho zoo tagnrho hydrated lub xeev, cov kab qhuav los ntawm dryness tuaj yeem tiv thaiv tau zoo thiab txhim kho.
6. Txhim khu kev nkag mus thiab kev ua tau zoo ntawm lwm cov khoom xyaw nquag
Polyglutamic acid muaj qee qib ntawm bioadhesion, uas tuaj yeem pab lwm cov khoom xyaw nquag (xws li vitamin C, nicotinamide, peptides, thiab lwm yam) nyob rau ntawm daim tawv nqaij ntev dua, ua rau muaj feem ntau ntawm lawv txoj kev nqus thiab kev siv.
Qhov "hydrated ib puag ncig" nws tsim rau ntawm daim tawv nqaij nws tus kheej kuj pab soften lub stratum corneum, ua rau nws yooj yim dua rau dej -soluble Cheebtsam nkag mus.
3.Polyglutamic acid ntawm qhov sib txawv molecular hnyav thiab lawv cov kev ua haujlwm tsom
Zoo li ntau cov khoom xyaw nquag, qhov ua tau zoo ntawm polyglutamic acid kuj tseem cuam tshuam nrog nws qhov hnyav molecular.
(1)Siab molecular hnyav polyglutamic acid
Nws tsuas yog ua haujlwm rau ntawm daim tawv nqaij.
Muaj nuj nqi:Zaj duab xis zoo heev- sib sau, dej- xauv, nrawm nrawm sau, thiab daim tawv nqaij du.
Daim tawv nqaij xav:Nws feem ntau ua rau cov tawv nqaij du thiab tsis yog- nplaum.
(2)Tsawg molecular hnyav polyglutamic acid
Nws tuaj yeem nkag mus tob rau hauv daim tawv nqaij (lub epidermis thiab txawm tias lub dermis superficial).
Kev Ua Haujlwm: Txhawb kev tsim cov collagen thiab hyaluronic acid los ntawm sab hauv, ncaj qha inhibits melanocytes, thiab ua tiav bio{0}} qib tiv thaiv - laus thiab ci.
