Ceramide yog dab tsi?
Ceramideyog ib chav kawm ntawm phospholipids nrog ceramide ua cov pob txha, feem ntau suav nrog ceramide phosphorylcholine thiab ceramide phosphoethanolamine. Phospholipids yog cov khoom tseem ceeb ntawm cov cell membrane, thiab 40 feem pua rau 50 feem pua ntawm cov sebum nyob rau hauv stratum corneum yog tsim los ntawm ceramide, uas yog ib feem tseem ceeb ntawm intercellular matrix thiab plays lub luag hauj lwm tseem ceeb hauv kev tswj cov dej tshuav ntawm lub stratum. corneum.
Raws li cov khoom nruab nrab ntawm cov stratum corneum hlwb, ceramide suav txog li 50 feem pua. Thaum cov ceramides thiab cov hlwb raug teeb tsa tsis tu ncua, stratum corneum yog cov qauv ua tiav thiab muaj zog, uas tuaj yeem kaw cov dej noo thiab tiv thaiv nws los ntawm cov stimuli sab nraud, thiab cov tsos yuav zoo li supple thiab flawless.
Cov kev tshawb fawb soj ntsuam tau pom tias nrog lub hnub nyoog, cov ntsiab lus ntawm ceramides hauv lub cev txo qis, tshwj xeeb tshaj yog nyob rau hauv lub ntsej muag thiab tes. Kev noj zaub mov tsis tu ncua ntawm ceramide tuaj yeem cuam tshuam cov tawv nqaij laus thiab ua kom cov hluas muaj zog.
Lub luag haujlwm tseem ceeb ntawm ceramide
● Moisturizing nyhuv
Cov dej noo thiab elasticity ntawm daim tawv nqaij yog ze ze rau cov dej noo nyob rau hauv lub epidermis. Kev poob ntawm daim tawv nqaij ntau dhau yuav ua rau cov tawv nqaij qhuav thiab txawm tias tawv nqaij tawv. Tom qab kev tshawb fawb, nws tau pom tias ceramide muaj lub peev xwm los koom nrog cov dej molecules, thiab nws tswj cov tawv nqaij noo los ntawm kev tsim cov qauv hauv lub stratum corneum.
● Anti-allergic nyhuv
Cov kev tshawb fawb tau pom tias ceramide ua lub luag haujlwm tseem ceeb hauv kev tswj hwm ntawm daim tawv nqaij ua haujlwm. Kev sim tau ua pov thawj tias daim ntawv thov hauv zos ntawm qee yam ntawm ntuj thiab hluavtaws ceramide tuaj yeem kho qhov poob ntawm daim tawv nqaij teeb meem kev ua haujlwm los ntawm kev siv cov kuab tshuaj organic thiab surfactants, yog li nws muaj txiaj ntsig zoo ntawm kev tiv thaiv daim tawv nqaij tiv thaiv kev ua xua. Ceramides tuaj yeem pab ua kom lub ntsej muag stratum corneum, txhim kho kev kam rau ntawm tag nrho cov tawv nqaij, tiv thaiv kev cuam tshuam ntawm cov khoom tsis zoo los ntawm sab nraud, zam qhov tshwm sim ntawm kev ua xua, thiab muaj cov nyhuv kho ntshav liab.
● Anti-aging, pab dawb thiab tiv thaiv oxidation
Thaum lub sij hawm kev laus ntawm daim tawv nqaij, lipid synthesis txo, thiab cov ntsiab lus ntawm ceramide nyob rau hauv lub stratum corneum txo. Cov yam ntxwv ntawm daim tawv nqaij laus yog: (1) daim tawv nqaij qhuav, desquamation, roughness, thiab poob ntawm luster; (2) thinning ntawm cuticle ntawm daim tawv nqaij, nce wrinkles, thiab txo elasticity. Kev siv cov ceramide tuaj yeem ua rau cov ntsiab lus ntawm ceramide nyob rau hauv stratum corneum ntawm epidermis, uas tuaj yeem txhim kho dryness, desquamation, thiab roughness ntawm daim tawv nqaij; Nyob rau tib lub sijhawm, ceramide tuaj yeem ua kom cov tuab ntawm stratum corneum ntawm lub epidermis, txhim kho daim tawv nqaij cov dej tuav lub peev xwm, txo cov wrinkles, ua kom tawv nqaij elasticity, thiab ncua kev laus. kev laus.
