Nws yog hais tias peb lub ntsiab ntawmtu tawv nqaijyogntxuav, moisturizing thiabtiv thaiv tshav ntuj, txhua qhov yog qhov tseem ceeb.Peb feem ntau pom cov ntawv tshaj tawm tshuaj pleev ib ce rov hais dua txog qhov tseem ceeb ntawm moisturizing ntawm daim tawv nqaij thiab kaw cov dej noo, tab sis koj puas paub tias cov tshuaj twg muaj cov nyhuv moisturizing?Koj puas paub tias qeb twg pom cov khoom xyaw glycerin, ceramide, thiab hyaluronic acid yog?
Hauv cov tshuaj pleev ib ce moisturizing, muaj plaub pawg ntawm cov xim uas tuaj yeem ua lub luag haujlwm moisturizing: cov khoom xyaw roj, hygroscopic me me molecule compounds, hydrophilic macromolecular compounds thiab kho cov khoom xyaw.
1. Cov roj thiab cov rog
Xws li Vaseline, txiv roj roj, roj almond, thiab lwm yam. Cov khoom siv raw no tuaj yeem tsim cov roj nplaum rau ntawm daim tawv nqaij tom qab siv, uas yog sib npaug rau npog daim tawv nqaij nrog ib txheej ntawm cov yeeb yaj kiab tshiab, uas plays lub luag haujlwm hauv qeeb cov dej poob hauv stratum corneum thiab tswj cov dej noo ntawm stratum corneum.
2. Hygroscopic me me molecule tebchaw
Nwsmoisturizingcov khoom xyaw feem ntau yog me me-molecule polyols, acids, thiab ntsev;Lawv yog cov dej-absorbent thiab tuaj yeem nqus dej noo los ntawm ib puag ncig ib puag ncig, yog li ua kom cov dej noo ntawm daim tawv nqaij cuticles.Feem ntau muaj xws li glycerol, butylene glycol, thiab lwm yam. Txawm li cas los xij, vim nws qhov muaj zog hygroscopicity, cov khoom siv moisturizing no tsis haum rau lub caij ntuj sov heev thiab lub caij ntuj no txias thiab qhuav thaum siv ib leeg lossis diluted.Nws tuaj yeem txhim kho los ntawm kev sib xyaw cov roj thiab cov rog.
3. Hydrophilic macromolecular compounds
Feem ntau polysaccharides thiab qee cov polymers.Tom qab o nrog dej, nws muaj peev xwm tsim ib tug spatial network qauv, uas combines dawb dej kom cov dej tsis yooj yim ploj, yog li ua lub luag hauj lwm ntawm moisturizing.Feem ntau, cov khoom siv raw no muaj cov yeeb yaj kiab tsim thiab muaj cov tawv nqaij zoo nkauj.Tus neeg sawv cev raw khoom yog cov paub zoo hyaluronic acid.Nws muaj ntau yam kev siv, muaj kev nyab xeeb thiab maj mam, muaj qhov pom tseeb moisturizing nyhuv, thiab haum rau txhua hom tawv nqaij thiab huab cua puag.
4. Restorative cov khoom xyaw
Xws li ceramide, phospholipids thiab lwm yam lipid Cheebtsam.Lub stratum corneum yog lub cev lub ntuj tsim.Yog tias qhov cuam tshuam kev ua haujlwm raug txo, daim tawv nqaij yuav yooj yim poob dej.Ntxiv cov khoom siv raw uas txhim khu kev ua haujlwm ntawm cov stratum corneum rau hauv cov khoom siv moisturizing tuaj yeem txo cov tawv nqaij cov dej tsis zoo thiab ua tiav cov nyhuv moisturizing.Lawv zoo li cov kws kho cuticle.
