Kodi ndi zinthu ziti zosamalira khungu zomwe zimakhala ndi mphamvu yonyowetsa khungu?

Akuti zinthu zitatu zachisamaliro chakhungundikuyeretsa, kunyowetsa ndichitetezo cha dzuwa, chilichonse mwa izi n'chofunika kwambiri. Nthawi zambiri timaona malonda otsatsa zodzoladzola mobwerezabwereza akunena za kufunika konyowetsa khungu ndi kutseka chinyezi, koma kodi mukudziwa zinthu zomwe zimapangitsa kuti chinyezi chikhale chonyowa? Kodi mukudziwa gulu lomwe glycerin, ceramide, ndi hyaluronic acid zimachokera?

Mu zodzoladzola zopatsa chinyezi, pali mitundu inayi ya utoto yomwe ingathandize kupatsa chinyezi: zosakaniza zamafuta, mankhwala ang'onoang'ono a hygroscopic, mankhwala a macromolecular a hydrophilic ndi zosakaniza zokonzanso.

1. Mafuta ndi mafuta

Monga Vaseline, mafuta a azitona, mafuta a amondi, ndi zina zotero. Mtundu uwu wa zinthu zopangira ukhoza kupanga filimu ya mafuta pakhungu mutagwiritsa ntchito, zomwe zikufanana ndi kuphimba khungu ndi filimu yosungiramo zinthu zatsopano, yomwe imagwira ntchito yochepetsa kutayika kwa madzi mu stratum corneum ndikusunga chinyezi cha stratum corneum.

2. Mankhwala ang'onoang'ono a molecule osawoneka bwino

ZakekunyowetsaZosakaniza zake zimakhala ma polyol ang'onoang'ono, ma acid, ndi mchere; zimayamwa madzi ndipo zimatha kuyamwa chinyezi kuchokera kumalo ozungulira, zomwe zimapangitsa kuti chinyezi chikhale m'ma cuticles a khungu. Zodziwika bwino ndi glycerol, butylene glycol, ndi zina zotero. Komabe, chifukwa cha hygroscopicity yake yamphamvu, mtundu uwu wa chosakaniza chonyowetsa siwoyenera nthawi yachilimwe yonyowa kwambiri komanso yozizira komanso youma ikagwiritsidwa ntchito yokha kapena kuchepetsedwa. Itha kukonzedwa bwino pophatikiza mafuta ndi mafuta.

3. Mankhwala osakanikirana ndi mamolekyulu a hydrophilic

Kawirikawiri ma polysaccharide ndi ma polima ena. Madzi akatupa, amatha kupanga mawonekedwe a netiweki, omwe amaphatikiza madzi omasuka kuti madzi asatayike mosavuta, motero amatenga gawo pakunyowetsa. Kawirikawiri, zinthu zopangira izi zimakhala ndi mphamvu yopangira filimu ndipo zimakhala ndi khungu losalala. Choyimira choyimira ndi hyaluronic acid yodziwika bwino. Ili ndi ntchito zosiyanasiyana, ndi yotetezeka komanso yofewa, imakhala ndi mphamvu yonyowetsa, ndipo ndi yoyenera mitundu yonse ya khungu ndi nyengo.

4. Zosakaniza zobwezeretsa

Monga ceramide, phospholipids ndi zinthu zina zamafuta. Stratum corneum ndiye chotchinga chachilengedwe cha thupi. Ngati ntchito yotchinga yachepa, khungu lidzataya chinyezi mosavuta. Kuwonjezera zinthu zopangira zomwe zimawonjezera ntchito yotchinga ya stratum corneum mu zinthu zonyowetsa khungu kungachepetse bwino kutaya madzi pakhungu ndikupeza mphamvu yonyowetsa khungu. Ali ngati okonza khungu.
