Osmolyte z’umwimerere ni ubwoko bw’ibintu bikoresha imiti bigumana imiterere yihariye y’uturemangingo kandi birwanya umuvuduko w’imikorere ya osmotic kugira ngo bihamye formula ya macromolecular. Urugero, isukari, polyols za polyether, karubohidrati n’ibindi binyabutabire, betaine ni ikintu cy’ingenzi kinyuramo mu mubiri.

Ubushakashatsi bwa siyansi buriho bwerekana ko uko ibidukikije byumye cyangwa bifite umunyu mwinshi, ni ko betaine nyinshi mu turemangingo twa mikorobe.

Uturemangingo tw’uruhu duhindura ingano ya osmolyte mu turemangingo bitewe n’uko osmolyte y’umwimerere yakusanyijwe cyangwa yarekuwe, kugira ngo tugumane ingano n’amazi mu turemangingo.

Iyo umuvuduko mwinshi w’inyuma wa osmotiki, nko kubura amazi mu ruhu cyangwa imirasire ya ultraviolet, bizatera gusohoka kwa osmotiki mu turemangingo tw’uruhu, bigatuma uturemangingo tw’inyuma tw’uruhu tubura, kandi osmotiki ya betaine ishobora kubangamira cyane igikorwa cyose.

Iyo betaine ikoreshejwe mu bikoresho byo kwiyitaho, ikoreshwa nk'ikintu kiyinjiza mu mubiri kugira ngo igumane uburyo bwo kwinjira mu turemangingo hakurikijwe uko uruhu rwinjira, kugira ngo rwongere ubushuhe bw'uruhu rwo hejuru. Ihame ryihariye ryo koroshya ubushuhe rya betaine rituma imiterere yayo yo koroshya ubushuhe itandukanye n'iy'ibisanzwe byo koroshya ubushuhe.

Ugereranyije na gel ya aside hyaluronic, beterave nubwo yaba iri ku rugero ruto ishobora kugira ingaruka nyazo zo kwisiga igihe kirekire.

Isosiyete y’Abafaransa yitwa L’Oreal yo mu bwoko bwa Vichy fountain deep moisturizing yongereraho ibintu nk’ibyo. Amatangazo yayo yo kwamamaza avuga ko iyi porogaramu ishobora gukurura ubushuhe bw’uruhu mu ruhu hakoreshejwe amazi make, kugira ngo irusheho gutera imbere uruhu rufite amazi ahagije.
