Nyob rau hauv xyoo tas los no, "peptides" tau dhau los ua cov lus nrov thoob plaws ntau yam khoom noj qab haus huv thiab kev noj qab haus huv. Txaus siab los ntawm cov khoom siv-savvy cov neeg siv khoom, peptides tau ua lawv txoj hauv kev los ntawm kev tu plaub hau thaum ntxov thiab cov tshuaj ntxiv rau hnub no cov kab kev tu tawv nqaij siab. Tam sim no, lawv tau raug qhuas tias yog qhov loj tom ntej tom qab hyaluronic acid. Tab sis dab tsi yog peptides, thiab vim li cas lawv thiaj li tau txais kev saib xyuas ntau?
Peptides yog dab tsi?
Txhawm rau nkag siab peptides, peb yuav tsum xub nkag siab lo lus "peptide" nws tus kheej. Lub peptide yog ib qho sib xyaw ua ke ntawm α-amino acids txuas ua ke los ntawm peptide bonds. Nws yog ib yam khoom uas feem ntau pom nyob rau hauv tib neeg lub cev thiab feem ntau sawv cev rau qhov nruab nrab ntawm kev puas tsuaj ntawm cov proteins.
Yog li, puas yog peptides tsuas yog sau cov amino acids? Hauv essence, yog. Tus naj npawb ntawm cov amino acid units txiav txim seb hom peptide: ob amino acids tsim ib dipeptide, peb tsim tripeptide, thiab lwm yam. Thaum ib cov saw ntau tshaj 50 amino acids, nws yog feem ntau cais raws li ib tug protein. Feem ntau, ib qho peptide uas muaj peb lossis ntau dua cov amino acids raug xa mus ua ib qhopolypeptide.
Nyob rau hauv tib neeg lub cev, peptides ua lub luag haujlwm tseem ceeb hauv ntau yam kev ua haujlwm lom neeg - tswj cov tshuaj hormones, txhawb kev sib txuas lus neural, pab kev tsim tawm, thiab pab txhawb kev loj hlob ntawm tes. Lawv tuaj yeem qhib cov enzymes, tswj DNA transcription, thiab cuam tshuam cov protein synthesis, yog li ua rau muaj kev cuam tshuam ntawm lub cev. Qhov tseeb, ntau yam khoom siv hauv peb lub cev muaj nyob hauv daim ntawv peptide, ua rau lawv tseem ceeb rau tib neeg kev noj qab haus huv.
Peptides hauv Skincare: Functions and Types
Hauv kev tu tawv nqaij, peptides feem ntau yog categorized raws li lawv cov haujlwm tseem ceeb, suav nrogteeb liab peptides, cov kab mob peptides, thiabinhibitor peptides.
Cov teeb liab peptides ua raws li cov neeg xa xov, xa cov cim rau ntawm daim tawv nqaij los txhawb kev tsim cov collagen thiab elastin. Qhov no ua rau cov tawv nqaij firmer, zoo nkauj dua thiab muab cov txiaj ntsig tiv thaiv kev laus. Piv txwv xws li Palmitoyl Pentapeptide-3, Palmitoyl Tripeptide-1, Palmitoyl Hexapeptide, thiab Palmitoyl Tripeptide-5.
Carrier peptides pab thauj cov kab mob, xws li tooj liab, mus rau qhov chaw ntawm kev ua haujlwm enzymatic. Qhov no txhawb kev tsim collagen thiab elastin, pab kho qhov txhab, thiab txhawb kev tsim cov hlab ntsha tshiab. Ib qho piv txwv zoo yog Copper Tripeptide-1.
Inhibitor peptides ua haujlwm los ntawm kev so ntawm lub ntsej muag cov leeg, softening wrinkles tshwm sim los ntawm cov leeg rov ua dua. Cov peptides no tshwj xeeb tshaj yog nrov hauv cov khoom tu lub ntsej muag tsom cov kab qhia. Piv txwv xws li Acetyl Hexapeptide-3, Acetyl Octapeptide-1, dipeptide derivatives ntawm nab venom, thiab Pentapeptide-3.
Puas muaj tej yam downsides?
Piv nrog rau cov khoom xyaw ua kom nrawm dua li AHAs lossis retinoids, peptides yuav xa cov txiaj ntsig ntau dua. Cov teebmeem tshwm sim tuaj yeem siv sijhawm ntau lub lis piam lossis ntau lub hlis kom tshwm sim, uas txhais tau hais tias kev sib xws thiab kev ua siab ntev yog qhov tseem ceeb thaum siv peptide-based skincare.
Tsis tas li ntawd, peptide extraction thiab synthesis yog cov txheej txheem nyuaj uas ua rau cov nqi ntau lawm. Yog li ntawd, cov khoom zoo peptide feem ntau kim dua. Cov neeg siv khoom yuav tsum tau ceev faj nrog cov khoom pheej yig uas thov kom muaj peptides, vim tias qhov tseeb concentration lossis kev ua tau zoo yuav muaj lus nug.
Tshaj Skincare: Cov ntawv thov kho mob
Peptides tsis yog ib qho khoom siv tu tawv nqaij xwb - lawv kuj tau txais kev sib tw hauv kev kho mob. Lawv tab tom tshawb nrhiav rau kev siv tshuaj tiv thaiv peptide, tshuaj tiv thaiv kab mob, thiab lwm yam tshuaj kho tshiab. Raws li kev tshawb fawb txuas ntxiv mus, qhov dav dav ntawm peptides hauv tib neeg kev noj qab haus huv thiab tshuaj yuav tsum loj hlob.
