Ceramides yog ib tsev neeg ntawm ib txwm muaj lipids uas ua feem ntau nyob rau hauv daim tawv nqaij txheej saum toj kawg nkaus, tsim ib qho kev tiv thaiv thiab txo cov natural transepidermal dej poob.Ceramides kho lub stratum corneum txheej nyob rau hauv cov ntaub ntawv ntawm cov tawv nqaij qhuav, txhim kho daim tawv nqaij hydration, thiab ua rau kom cov kev xav ntawm softness.Lawv muaj txiaj ntsig zoo rau kev ntxhov siab, rhiab, scaly, ntxhib, qhuav, hnub nyoog, thiab cov tawv nqaij puas.Ceramides ua lub luag haujlwm tseem ceeb hauv cov qauv ntawm cov txheej txheem epidermal thiab tsim ib feem tseem ceeb ntawm cov cell membrane network.Lawv pab tsim thiab txhawb nqa daim tawv nqaij txoj haujlwm.Qhov no yog qhov tseem ceeb heev: yog tias lub stratum corneum lub hydration yog khaws cia, ces nws ua hauj lwm ntau dua nyob rau hauv cov nqe lus ntawm saj zawg zog thiab desquamation, nws kev ncaj ncees yog upheld, thiab daim tawv nqaij yog tsis tshua muaj rau khaus.Ceramide ntau lawm txo nrog lub hnub nyoog, accentuating tej yam nyiam rau cov tawv nqaij qhuav.Thaum muab tso rau hauv kev npaj kho mob ntawm daim tawv nqaij, cov tshuaj pleev ib ce ntawm ceramides tuaj yeem muaj txiaj ntsig zoo rau stratum corneum yog tias cov ceramides tswj kom sau cov chaw sib txuas thiab yog tias lawv tau hydrolyzed los ntawm qhov tseeb extracellular enzymes ntawm daim tawv nqaij.Xws li daim ntawv thov kuj tuaj yeem txhawb kev tsim cov ceramide hauv daim tawv nqaij, yog li ua rau daim tawv nqaij cov ntsiab lus lipid thiab txhawb cov tawv nqaij tiv thaiv kev tiv thaiv, ntsuas los ntawm transepidermal dej poob.Cov tshuaj pleev xim rau cov ceramides tau pom tias ntes thiab khi dej, tsim nyog rau daim tawv nqaij kom nyob twj ywm, du, thiab hydrated.natural ceramides yog tau los ntawm cov tsiaj thiab nroj tsuag.Thaum cov ceramides tuaj yeem tsim cov khoom siv hluavtaws, nws yog ib qho nyuaj kom tau txais ib qho zoo sib xws rau cov uas pom nyob rau hauv qhov, ua rau lawv kim raw khoom.
