FAQ

Q1: Dipeptide-4 (Cys-Gly) pab ua kom daim tawv nqaij ci ntsa iab li cas dhau ntawm nws cov teebmeem antioxidant?

A: Dipeptide-4 ua rau daim tawv nqaij ci ntsa iab los ntawm ob txoj kev ua haujlwm uas nthuav dav tshaj qhov kev tiv thaiv antioxidant yooj yim. Ua ntej, nws cov haujlwm tiv thaiv glycation tiv thaiv kev tsim cov AGEs, uas yog lub luag haujlwm rau qhov daj thiab dulling ntawm collagen fibers - ib qho tseem ceeb ua rau daim tawv nqaij sallow, lackluster. Los ntawm kev khaws cia collagen clarity, Dipeptide-4 pab tswj kom muaj lub ntsej muag translucent, radiant. Qhov thib ob, ua ke nrog lwm cov cysteine-muaj peptides xws li GSH thiab γ-GC, Dipeptide-4 synergistically inhibits tyrosinase kev ua haujlwm, txo cov melanin synthesis thiab txhawb kom muaj lub ntsej muag zoo dua.

Q2. Lub tshuab ua haujlwm ntawm Dipeptide-4 (L-Cysteinylglycine) ua tus thawj coj glutathione yog dab tsi thiab nws piv rau glutathione ncaj qha hauv cov tshuaj tiv thaiv kev laus li cas?

A: Dipeptide-4 ( L-Cysteinylglycine) yog ib qho glutathione precursor los ntawm lub voj voog γ-glutamyl, rov tsim glutathione kom tswj tau qhov sib npaug redox. Piv rau glutathione ncaj qha, nws muaj qhov me me (178 Da vs 307 Da) rau kev nkag mus zoo dua, ruaj khov dua hauv cov qauv, thiab ua haujlwm ua ib qho metabolic intermediate. Cov pov thawj hauv kev kho mob txhawb nqa nws cov txiaj ntsig antioxidant thiab anti-glycation, thaum glutathione ncaj qha muaj kev ua haujlwm tsawg. Rau cov khoom tiv thaiv kev laus, Dipeptide-4 zoo dua vim muaj kev ruaj khov, nkag mus, thiab kev ua haujlwm pov thawj.

Q3. Dipeptide-4 (L-Cysteinylglycine) nyob rau hauv cov tshuaj pleev ib ce uas muaj dej ruaj khov npaum li cas, thiab cov pH thiab qhov kub zoo tshaj plaws yog dab tsi los khaws nws cov tshuaj antioxidant thiab anti-glycation?

Dipeptide-4 ( L-Cysteinylglycine) ruaj khov hauv cov dej ntawm pH 5.5-7.0. Tsis txhob siv cov kua qaub muaj zog (pH<3.5) thiab cov hauv paus muaj zog. Ntxiv rau qhov kub qis dua 40°C; kev ua kom sov ntev yuav ua rau cov haujlwm puas tsuaj. Khaws cov khoom siv raw ntawm 2-8°C txog li peb xyoos. Tsis txhob siv cov hlau ions muaj zog xws li Fe³⁺ thiab Cu²⁺. Kev ua raws li cov xwm txheej no yuav ua rau cov tshuaj antioxidant thiab anti-glycation ua haujlwm tau zoo thoob plaws lub sijhawm khaws cia.

Q4. Puas siv tau Dipeptide-4 (L-Cysteinylglycine) nrog lwm cov peptides tiv thaiv kev laus (piv txwv li, Matrixyl, Argireline) lossis vitamin C derivatives yam tsis poob qhov ua tau zoo? Muaj cov teebmeem synergistic twg tau tshaj tawm?

Yog lawm, Dipeptide-4 ( L-Cysteinylglycine) sib xyaw zoo nrog lwm yam khoom siv. Nrog rau cov vitamin C derivatives (piv txwv li, AA2G), nws muab cov teebmeem synergistic dual-pathway antioxidant. Nrog Argireline, nws tsom mus rau cov wrinkles dynamic thiab static. Nrog Matrixyl, cov txheej txheem ua kom tiav: Matrixyl txhawb nqa collagen, Dipeptide-4 muab cov txiaj ntsig antioxidant thiab anti-glycation. Nrog niacinamide, nws txhim kho anti-glycation thiab txhim kho cov tawv nqaij. Siv cov vitamin C derivatives stabilized es tsis txhob siv cov kua qaub L-ascorbic ntshiab. Dipeptide-4 yog qhov ua tau zoo heev thiab synergistic.

Q5. Cov tshuaj Dipeptide-4 (L-Cysteinylglycine) uas pom zoo kom siv ntau npaum li cas rau cov khoom uas tsis tas siv lawm kom tiv thaiv kev lwj thiab cov tshuaj antioxidant, thiab puas muaj kev txhawj xeeb txog kev nyab xeeb lossis kev khaus rau cov tawv nqaij rhiab heev?

Rau cov khoom uas tsis siv tshuaj pleev, cov tshuaj pom zoo yog 0.1% -1.0% rau cov tshuaj pleev/tshuaj pleev tiv thaiv kev laus; rau cov tawv nqaij rhiab heev, 0.05% -0.2%. Qhov tsawg kawg nkaus ntawm kev siv tau zoo yog 0.05%. Kev Nyab Xeeb: 2023 CIR xaus lus tias muaj kev nyab xeeb rau kev siv pleev kom zoo nkauj. Sau npe hauv Suav teb (siv ntau tshaj plaws 0.005% uas tsis siv tshuaj pleev) thiab Nyiv Pooj. Feem ntau cov tawv nqaij zam tau zoo. Tsis tshua muaj liab me ntsis thaum siv ntau dhau. Kev sim thaj rau cov tawv nqaij rhiab heev. 0.05% -1.0% zoo thiab muaj kev nyab xeeb; pib ntawm 0.05% rau cov tawv nqaij rhiab heev.
