Cov osmolytes organic yog ib hom tshuaj lom neeg uas tswj cov metabolism tshwj xeeb ntawm cov cell thiab tiv taus lub osmotic ua haujlwm siab los tswj cov mis macromolecular. Piv txwv li, qab zib, polyether polyols, carbohydrates thiab cov tshuaj sib xyaw, betaine yog ib qho tseem ceeb organic permeable substance.

Cov kev tshawb fawb uas twb muaj lawm qhia tau hais tias qhov qhuav lossis salinity ntawm ib puag ncig ntuj ntau dua, qhov ntau dua cov betaine hauv cov hlwb microbial.

Cov tawv nqaij hloov pauv qhov concentration ntawm osmolyte hauv cov hlwb raws li cov organic osmolyte uas tau sau lossis tso tawm, yog li ntawd thiaj li tswj tau qhov ntim thiab dej sib npaug ntawm cov hlwb.

Thaum lub siab osmotic ua haujlwm sab nraud, xws li daim tawv nqaij epidermal dehydration lossis ultraviolet radiation, yuav ua rau muaj ntau cov osmotic tshuaj tawm hauv cov hlwb tawv nqaij, ua rau apoptosis ntawm cov hlwb tawv nqaij sab nraud, thiab betaine osmotic tshuaj tuaj yeem cuam tshuam tag nrho cov txheej txheem.

Thaum betaine siv rau hauv cov khoom siv tu tus kheej, nws yog siv los ua cov organic penetrant los tswj qhov sib npaug ntawm cov cell raws li qhov nkag mus rau hauv cuticle ntawm daim tawv nqaij, yog li txhim kho cov dej noo ntawm daim tawv nqaij. Lub hauv paus ntsiab lus tshwj xeeb ntawm betaine ua rau nws cov yam ntxwv moisturizing txawv ntawm cov moisturizers feem ntau.

Piv nrog hyaluronic acid gel, beet txawm tias nyob rau hauv qis concentration tseem tuaj yeem muaj qhov cuam tshuam tiag tiag ntawm kev noo noo mus sij hawm ntev.

Fabkis L'Oreal's Vichy fountain deep moisturizing product ntxiv cov khoom xyaw no. Nws cov "tap water" deep moisturizing advertising hais tias cov khoom no tuaj yeem rub cov dej noo tob tob ntawm daim tawv nqaij rau ntawm daim tawv nqaij nrog dej tsawg dua, yog li ua kom daim tawv nqaij nto muaj dej txaus.
