Bivugwa ko ibintu bitatu byakwita ku ruhunikweza, kuvomera kandikurinda izuba, buri kimwe muri byo ni ngombwa. Dukunze kubona amatangazo yo kwisiga yamamaza inshuro nyinshi avuga akamaro ko gutobora uruhu no gufunga ubuhehere, ariko uzi ibintu bigira ingaruka nziza? Waba uzi icyiciro gikunze kugaragara glycerine, ceramide, na aside hyaluronic?
Mu kwisiga amavuta yo kwisiga, hari ibyiciro bine bya pigment bishobora kugira uruhare runini: ibikoresho byamavuta, Hygroscopique ntoya ya molekile ntoya, hydrophilique macromolecular hamwe nibisanwa.
1. Amavuta n'ibinure
Nka Vaseline, amavuta ya elayo, amavuta ya almonde, nibindi. Ubwoko bwibikoresho fatizo birashobora gukora firime yamavuta hejuru yuruhu nyuma yo kuyikoresha, ibyo bikaba bihwanye no gupfuka uruhu urwego rwa firime ibika neza, ikagira uruhare muri gutinda gutakaza amazi muri stratum corneum no gukomeza ubuhehere buri muri stratum corneum.
2. Hygroscopique ntoya ya molekile
Yayoamaziibiyigize ahanini ni mato-molekile polyole, acide, nu munyu; zikurura amazi kandi zirashobora gukuramo ubuhehere buturuka ku bidukikije, bityo bikongerera ubushuhe bwa cicicles y'uruhu. Mubisanzwe harimo glycerol, butylene glycol, nibindi, ariko, kubera hygroscopique ikomeye, ubu bwoko bwibintu bitanga amazi ntibikwiriye kubihe byizuba ryinshi nubukonje nubukonje bwumye iyo bikoreshejwe wenyine cyangwa bivanze. Irashobora kunozwa muguhuza amavuta namavuta.
3. Hydrophilique macromolecular ibice
Mubisanzwe polysaccharide na polymers zimwe. Nyuma yo kubyimba n'amazi, irashobora gukora imiyoboro y'urusobekerane, ihuza amazi yubusa kugirango amazi atazimira byoroshye, bityo bikagira uruhare mukubura amazi. Mubisanzwe, ibi bikoresho bibisi bifite ingaruka zo gukora firime kandi bifite uruhu rworoshye. Ibikoresho fatizo bihagarariye ni aside izwi cyane ya hyaluronic. Ifite uburyo butandukanye bwo gukoresha, ifite umutekano kandi yoroheje, ifite ingaruka zigaragara neza, kandi ikwiranye nubwoko bwose bwuruhu hamwe nikirere.
4. Ibikoresho byubaka
Nka ceramide, fosifolipide nibindi bigize lipide. Stratum corneum ni inzitizi yumubiri. Niba imikorere ya bariyeri igabanutse, uruhu ruzatakaza byoroshye. Ongeramo ibikoresho fatizo byongera imikorere ya barrière ya stratum corneum mubicuruzwa bitanga amazi birashobora kugabanya neza umuvuduko wamazi wuruhu kandi bikagira ingaruka nziza. Bameze nkabashinzwe gusana.
