Kuthiwa izinto ezintathu zeukhathalelo lolusuziukucoca, ukufumisa kunyeukukhuselwa elangeni, nganye kwezi ibalulekile. Sihlala sibona iintengiso zezithambiso ziphindaphinda zikhwaza ngokubaluleka kokufumisa ulusu nokuzivalela kumswakama, kodwa uyazi ukuba zeziphi izinto ezinefuthe lokufumisa? Ngaba uyazi ukuba zeziphi izithako eziqhele ukubonwa njenge-glycerin, i-ceramide, kunye ne-hyaluronic acid ezikweyiphi iklasi?
Kwizinto zokuthambisa ezifumisayo, kukho iindidi ezine zeepigment ezinokudlala indima yokufumisa: izithako zeoyile, iikhompawundi zemolekyuli encinci ezithambileyo, iikhompawundi ze-hydrophilic macromolecular kunye nezithako zokulungisa.
1. Iioyile namafutha
Ezifana neVaseline, ioyile yomnquma, ioyile ye-almond, njl. Olu hlobo lwezinto ezikrwada lunokwenza ifilimu yokuthambisa phezu kolusu emva kokusetyenziswa, okufana nokugubungela ulusu ngomaleko wefilimu ehlala icocekile, edlala indima ekunciphiseni isantya sokulahleka kwamanzi kwi-stratum corneum kunye nokugcina umxholo wokufuma we-stratum corneum.
2. Iikhompawundi zemolekyuli ezincinci ezithambileyo
YayoukufumisaIzithako ikakhulu zii-polyols ezincinci, ii-asidi, kunye neetyuwa; ziyafunxa amanzi kwaye zinokufunxa umswakama osuka kwindawo engqongileyo, ngaloo ndlela zonyusa umswakama wesikhumba. Eziqhelekileyo ziquka i-glycerol, i-butylene glycol, njl. Nangona kunjalo, ngenxa yokuba i-hygroscopicity yayo enamandla, olu hlobo lwesithako esifumisayo alufanelekanga kwihlobo elinomswakama kakhulu kunye nobusika obubandayo nobomileyo xa lusetyenziswa lodwa okanye luxutywe. Lungaphuculwa ngokudibanisa iioyile kunye namafutha.
3. Iikhompawundi ze-macromolecular eziphila emanzini
Ngokubanzi iipolysaccharides kunye neepolymers ezithile. Emva kokudumba ngamanzi, inokwenza isakhiwo senethiwekhi yendawo, esidibanisa amanzi akhululekileyo ukuze amanzi angalahleki lula, ngaloo ndlela idlala indima ekufumeni. Ngokubanzi, ezi zinto ziluhlaza zinefuthe lokwenza ifilimu kwaye zinolusu oluthambileyo. Izinto eziluhlaza ezimeleyo yi-hyaluronic acid eyaziwayo. Ineendlela ezahlukeneyo zokusetyenziswa, ikhuselekile kwaye ithambile, inefuthe elicacileyo lokufumisa, kwaye ifanelekile kuzo zonke iintlobo zeentlobo zesikhumba kunye neemeko zemozulu.
4. Izithako zokubuyisela kwimeko yesiqhelo
Ezifana ne-ceramide, i-phospholipids kunye nezinye izinto ze-lipid. I-stratum corneum sisithintelo sendalo somzimba. Ukuba umsebenzi wesithintelo uyancipha, ulusu luya kulahlekelwa lula kukufuma. Ukongeza izinto eziluhlaza eziphucula umsebenzi wesithintelo se-stratum corneum kwiimveliso zokufumisa kunokunciphisa ngempumelelo izinga lokulahleka kwamanzi eluswini kwaye kufezekise isiphumo sokufumisa. Zifana nabalungisi besikhumba.
