Zvinonzi zvinhu zvitatu zvekuchengetwa kwegandavarikuchenesa, moisturizing uyesun protection, chimwe nechimwe chazvo chinokosha.Isu tinowanzoona zvishambadzo zvezvizoro zvichiramba zvichishevedzera nezvekukosha kwekunyorovesa ganda uye kuvharika muunyoro, asi unoziva here kuti ndezvipi zvinhu zvine moisturizing mhedzisiro?Unoziva here kuti ndeapi chikamu chinowanzo onekwa zvinongedzo glycerin, ceramide, uye hyaluronic acid ndezvake?
Muzvizoro zvinonyorovesa, kune zvikamu zvina zvepigment zvinogona kuita basa rekunyorovesa: oiri zvinongedzo, hygroscopic madiki mamorekuru makomisheni, hydrophilic macromolecular makomponi uye kugadzirisa zvinongedzo.
1. Mafuta nemafuta
Zvakadai seVaseline, mafuta emuorivhi, mafuta emuarumondi, nezvimwewo. Rudzi urwu rwezvinhu zvakasvibirira zvinogona kugadzira firimu remafuta paganda repamusoro mushure mekushandiswa, izvo zvakaenzana nekufukidza ganda nejira remutsva-kuchengeta firimu, iro rinoita basa mu. kuderedza kurasikirwa kwemvura mu stratum corneum uye kuchengetedza mwando we stratum corneum.
2. Hygroscopic maduku mamorekuru makomboni
Zvayomoisturizingzvinosanganisa kazhinji madiki-morekuru polyols, asidhi, uye munyu;ivo vanotora mvura uye vanogona kutora unyoro kubva kunharaunda yakapoteredza, nokudaro vachiwedzera hunyoro hwehuputi hweganda.Zvakajairwa zvinosanganisira glycerol, butylene glycol, etc. Zvisinei, nekuda kwehygroscopicity yakasimba, rudzi urwu rwehutu hunopisa haruna kukodzera kutonhora kwakanyanya uye kutonhora uye kuoma kwechando kana kushandiswa kwega kana kuderedzwa.Inogona kuvandudzwa nekubatanidza mafuta nemafuta.
3. Hydrophilic macromolecular compounds
Kazhinji polysaccharides uye mamwe mapolymers.Mushure mekuputika nemvura, inogona kuumba hurongwa hwemambure enzvimbo, iyo inobatanidza mvura yakasununguka kuitira kuti mvura irege kurasika nyore nyore, nokudaro ichiita basa mukunyorovesa.Kazhinji, zvinhu izvi zvakasvibiswa zvine firimu-kugadzira maitiro uye zvine ganda rakatsetseka rinonzwa.Mumiririri mbishi zvinhu ndiyo inozivikanwa hyaluronic acid.Iine huwandu hwakawanda hwemashandisirwo, yakachengeteka uye yakapfava, ine yakajeka moisturizing maitiro, uye yakakodzera kune ese marudzi eganda uye mamiriro ekunze.
4. Kudzorera zvinhu
Zvakadai seceramide, phospholipids uye zvimwe lipid components.Iyo stratum corneum ndiyo inodzivirira yemuviri.Kana basa rekudzivirira rakaderedzwa, ganda richarasikirwa nyore nyore unyoro.Kuwedzera zvinhu zvakasvibirira zvinosimudzira basa rezvivharo zve stratum corneum muzvigadzirwa zvinonyorovesa zvinogona kunyatso kudzikisa ganda rekurasikirwa kwemvura uye kuwana hunyoro hunoita.Vakafanana nevanogadzirisa cuticle.
