Zvinonzi zvinhu zvitatu zvekuchengetedza gandavarikuchenesa, inonyorovesa uyedziviriro yezuva, chimwe nechimwe chazvo chakakosha. Tinowanzoona kushambadza kwezvizoro zvichiramba zvichidanidzira nezvekukosha kwekunyorovesa ganda uye kuvharira hunyoro, asi unoziva here kuti zvinhu zvipi zvine hunyoro? Unoziva here kuti glycerin, ceramide, uye hyaluronic acid zvinowanikwa muboka ripi?
Muzvizoro zvinonyorovesa, kune mhando ina dzemavara epigment anogona kuita basa renyorovesa: zvinhu zvinosanganiswa nemafuta, zvinhu zvinosanganiswa ne hygroscopic small molecule compounds, zvinhu zvinosanganiswa ne hydrophilic macromolecular compounds uye zvinhu zvinogadzirisa.
1. Mafuta nemafuta
Zvakaita seVaseline, mafuta emuorivhi, mafuta earumondi, nezvimwewo. Rudzi urwu rwezvinhu zvinogona kugadzira firimu remafuta pamusoro peganda mushure mekushandisa, izvo zvakafanana nekufukidza ganda nefirimu rekuchengetedza ganda, iro rinoita basa rekudzora kurasikirwa kwemvura mu stratum corneum uye kuchengetedza hunyoro hwe stratum corneum.
2. Makomputa madiki eHygroscopic
ZvayokunyorovesaZvishandiso zvacho zvinonyanya kuva mapolyol madiki, acids, uye munyu; zvinonwisa mvura uye zvinogona kunwisa hunyoro kubva munzvimbo yakapoteredza, zvichiita kuti hunyoro huwedzere muganda. Zvinowanzo shandiswa zvinosanganisira glycerol, butylene glycol, nezvimwewo. Zvisinei, nekuda kwehunyoro hwayo hwakasimba, rudzi urwu rwechinhu chinonyorovesa haruna kukodzera muzhizha rakanyorova zvakanyanya uye munguva yechando inotonhora uye yakaoma kana ikashandiswa yoga kana yakasanganiswa. Inogona kuvandudzwa nekubatanidza mafuta nemafuta.
3. Makemikoro eHydrophilic macromolecular
Kazhinji polysaccharides nemamwe mapolymer. Mushure mekuzvimba nemvura, inogona kugadzira chimiro che network, icho chinosanganisa mvura yakasununguka kuitira kuti mvura isarasike zviri nyore, nokudaro ichitamba basa mukuisa hunyoro. Kazhinji, zvinhu izvi zvine simba rekugadzira firimu uye zvine ganda rakatsetseka. Chinhu chinomiririra hyaluronic acid inozivikanwa zvikuru. Iine mashandisirwo akasiyana-siyana, yakachengeteka uye yakapfava, ine hunyoro hunooneka, uye yakakodzera marudzi ese eganda nemamiriro ekunze.
4. Zvinhu zvinogadzirisa mamiriro emuviri
Zvakadai seceramide, phospholipids nezvimwe zvikamu zvemafuta. Stratum corneum ndiyo chidziviriro chemuviri. Kana chidziviriro chikadzikira, ganda rinorasikirwa nehunyoro zviri nyore. Kuwedzera zvinhu zvinovandudza chidziviriro che stratum corneum muzvigadzirwa zvinonyorovesa kunogona kuderedza kurasikirwa nemvura paganda uye kuita kuti rinyorove. Vakafanana nevanogadzirisa cuticle.
