Ndi zinthu ziti zosamalira khungu zomwe zimakhala ndi zonyowa?

Akuti zinthu zitatu zachisamaliro chakhungundikuyeretsa, moisturizing ndichitetezo cha dzuwa, iliyonse yomwe ili yofunika kwambiri. Nthawi zambiri timawona malonda a zodzoladzola akufuula mobwerezabwereza za kufunika konyowetsa khungu ndi kutseka chinyezi, koma kodi mumadziwa kuti ndi zinthu ziti zomwe zimakhala ndi mphamvu zowonongeka? Kodi mukudziwa kuti glycerin, ceramide, ndi hyaluronic acid ndi gulu liti?

Mu zodzoladzola zonyowa, pali magulu anayi amitundu omwe amatha kugwira ntchito yonyowa: zosakaniza zamafuta, ma hygroscopic ang'onoang'ono a molekyulu, ma hydrophilic macromolecular compounds ndi kukonza zopangira.

1. Mafuta ndi mafuta

Monga Vaseline, mafuta a azitona, mafuta a amondi, etc. Mtundu uwu wa zopangira ukhoza kupanga filimu yamafuta pakhungu pambuyo pa ntchito, yomwe ili yofanana ndi kuphimba khungu ndi filimu yosungira mwatsopano, yomwe imagwira ntchito kuchepetsa kutaya kwa madzi mu stratum corneum ndi kusunga chinyezi cha stratum corneum.

2. Mamolekyu ang'onoang'ono a Hygroscopic

Zakewonyowazosakaniza zambiri yaing'ono-molecule polyols, zidulo, ndi mchere; amamwa madzi ndipo amatha kuyamwa chinyezi kuchokera kumadera ozungulira, motero amawonjezera chinyezi cha ma cuticles a khungu. Zomwe zimaphatikizika ndi glycerol, butylene glycol, etc. Komabe, chifukwa cha hygroscopicity yake yolimba, chosakaniza choterechi sichiyenera kuzizira kwambiri komanso nyengo yozizira komanso yowuma ikagwiritsidwa ntchito yokha kapena kuchepetsedwa. Ikhoza kusinthidwa mwa kuphatikiza mafuta ndi mafuta.

3. Hydrophilic macromolecular mankhwala

Nthawi zambiri ma polysaccharides ndi ma polima ena. Pambuyo pa kutupa ndi madzi, imatha kupanga mapangidwe amtundu wa malo, omwe amaphatikiza madzi aulere kuti madzi asatayike mosavuta, motero amasewera gawo lonyowa. Kawirikawiri, zipangizozi zimakhala ndi mafilimu opanga mafilimu ndipo zimakhala ndi khungu losalala. Zoyimira zopangira ndi hyaluronic acid yodziwika bwino. Ili ndi ntchito zambiri, imakhala yotetezeka komanso yofatsa, imakhala ndi zotsatira zowoneka bwino zonyowa, ndipo ndizoyenera mitundu yonse ya khungu ndi nyengo.

4. Zosakaniza zobwezeretsa

Monga ceramide, phospholipids ndi zigawo zina za lipid. The stratum corneum ndiye chotchinga chachilengedwe cha thupi. Ngati ntchito yotchinga yachepetsedwa, khungu lidzataya mosavuta chinyezi. Kuonjezera zopangira zomwe zimakulitsa chotchinga cha stratum corneum kukhala zinthu zonyowa zitha kuchepetsa kutayika kwamadzi pakhungu ndikupangitsa kuti pakhale chinyezi. Iwo ali ngati okonza cuticle.
