Kuthiwa izinto ezintathu zeukunakekelwa kwesikhumbakukhonaukuhlanza, okuthambisa futhiukuvikelwa kwelanga, ngasinye sazo sibalulekile. Sivame ukubona izikhangiso zezimonyo zimemeza ngokuphindaphindiwe ngokubaluleka kokuthambisa isikhumba nokuvalela umswakama, kodwa uyazi ukuthi yiziphi izinto ezinomphumela wokuthambisa? Uyazi ukuthi izithako ezivame ukubonakala i-glycerin, i-ceramide, ne-hyaluronic acid zingaphansi kwasiphi isigaba?
Ezimonyweni zokuthambisa, kunezinhlobo ezine zemibala engadlala indima yokuthambisa: izithako zamafutha, izakhi zama-molecule amancane angenawo umoya, izakhi zama-macromolecular ezisebenza emanzini kanye nezithako zokulungisa.
1. Amafutha namafutha
NjengeVaseline, uwoyela womnqumo, uwoyela we-alimondi, njll. Lolu hlobo lwezinto ezingavuthiwe lungakha ifilimu yamafutha ebusweni besikhumba ngemva kokusetshenziswa, okufana nokumboza isikhumba ngesendlalelo sefilimu yokugcina imisha, edlala indima ekunciphiseni ijubane lokulahleka kwamanzi ku-stratum corneum nokugcina okuqukethwe komswakama kwe-stratum corneum.
2. Ama-molecule amancane angenawo umswakama
KuyoukuthambisaIzithako ikakhulukazi ziyi-polyols ezincane zama-molecule, ama-acid, nosawoti; zimunca amanzi futhi zingamunca umswakama endaweni ezungezile, ngaleyo ndlela zandise umswakama wesikhumba. Ezivamile zifaka phakathi i-glycerol, i-butylene glycol, njll. Kodwa-ke, ngenxa yokuthi i-hygroscopicity yayo inamandla, lolu hlobo lwesithako esimanzi alufaneleki ehlobo elinomswakama kakhulu kanye nasebusika obubandayo nobomile uma lusetshenziswa lodwa noma luxutshwe. Lungathuthukiswa ngokuhlanganisa amafutha namafutha.
3. Ama-macromolecular compounds aphiliza amanzi
Ngokuvamile ama-polysaccharide kanye nama-polymer athile. Ngemva kokuvuvukala ngamanzi, angakha isakhiwo senethiwekhi yendawo, esihlanganisa amanzi akhululekile ukuze amanzi angalahleki kalula, ngaleyo ndlela edlala indima ekufakeni umswakama. Ngokuvamile, lezi zinto zokusetshenziswa zinomphumela wokwakha ifilimu futhi zinomuzwa wesikhumba obushelelezi. Izinto zokusetshenziswa ezimele yi-hyaluronic acid eyaziwayo. Inezinhlobo eziningi zokusetshenziswa, iphephile futhi imnene, inomphumela ocacile wokufumisa, futhi ifanele zonke izinhlobo zesikhumba kanye nezimo zezulu.
4. Izithako zokuvuselela
Njenge-ceramide, i-phospholipids nezinye izingxenye ze-lipid. I-stratum corneum iyisithiyo semvelo somzimba. Uma umsebenzi wesithintelo uncishisiwe, isikhumba sizolahlekelwa kalula umswakama. Ukwengeza izinto zokusetshenziswa ezithuthukisa umsebenzi wesithintelo se-stratum corneum emikhiqizweni yokuthambisa kunganciphisa ngempumelelo izinga lokulahlekelwa amanzi esikhumbeni futhi kufeze umphumela wokuthambisa. Bafana nabalungisi besikhumba.
