Chophimba Chopangira Chotsekereza Khungu Lanu
Mankhwala ndi zinthu zowonjezera zomwe zimapezeka m'madzi oundana omwe amachititsa kuti khungu likhale ndi kukopa makompyuta monga maginito. Kulankhula zamakono, timadzi timene timatulutsa timadzi timene timapanga timadzi timene timayambitsa ma hydrogen. Kulumikizana uku kumathandiza kuchepetsa khungu pokoka madzi kuchokera m'munsi mwa maselo.
Momwe Mankhwala Amagwirira Ntchito
Mankhwala amatha kugwira ntchito pokoka madzi kuchokera ku dermis (khungu lachiwiri la khungu) kupita ku epidermis (pamwamba pa khungu).
Izi zimawonjezera kuchuluka kwa chinyezi mu chidziwitso cha corneum , mndandanda wa maselo akufa omwe ali ndi kutuluka kwapadera kwa epidermis. Pochita zimenezi, khungu lidzawoneka losavuta ndipo silidzawoneka movutikira.
Mankhwalawa amalimbikitsanso kukhetsa maselo akufa (otchedwa dequamation ) mwa kuphwanya mapuloteni omwe amagwira maselo pamodzi. Ngati chinyezi chikuposa 70 peresenti, humectants akhoza kutulutsa mpweya wa madzi kuchokera mlengalenga kuti athandize kuchepetsa khungu.
Mitundu ya Humectants
Mankhwalawa amagwiritsidwa ntchito pazinthu zamakono ndi zosamalira zaumwini kuphatikizapo zipsera za tsitsi, oyeretsa thupi, mabala a nkhope, maso a maso, pambuyo pa dzuwa, frizz serums, ma balomo, ndi sopo zina.
Mankhwala amatha kukhala opangidwa ndi anthu kapena ochokera ku chilengedwe. Aliyense amagwira ntchito mosiyana ndipo akhoza kukhala ndi katundu omwe amawapangitsa kukhala oyenerera pazinthu zina. Chitsanzo chimodzi chotere ndi mtundu wa humectant wotchedwa gel nanolipid umene umagwiritsidwa ntchito pamapazi ambiri ndi chidendene chifukwa cha zinthu zake zokhazikika.
Humectants Zokwanira
Mankhwalawa amagwiritsidwa ntchito kwambiri m'magulitsidwe aumwini chifukwa ali otsika mtengo kuti azikhala ndi kukhala ndi moyo wamtali wautali wautali.
Ngakhale kuti maselo otchedwa humectants amatha kutseka chinyezi pamlingo winawake, sapereka zakudya zilizonse kapena zopindulitsa pakhungu.
Nthaŵi zina, amatha kusokoneza njira yowonjezera thupi ndipo amatha kuyanika khungu nthawi yaitali.
Zina mwazipangizo zamakono zotchuka zimaphatikizapo:
- Butylene glycol
- Urea
- Glycerin
- Kutuluka kwa Tremella
- Sorbitol
- Dicyanamide
- Sodium PCA
- Sodium lactate
Masewera Achilengedwe
Mankhwala oteteza zachilengedwe amakhala ndi cholinga chimodzi: kutulutsa chinyezi pamwamba pa khungu pamene khungu limatulutsa mphamvu. Amachita zimenezi ndi zinthu zomwe zimapangitsa kuti chinyezi chizikhala mumtambo ndikulimbikitsa kukula kwa maselo atsopano mu epidermis.
Zina mwa zozizwitsa zotchuka zachilengedwe zimaphatikizapo:
- Hyaluronic acid , mankhwala opangidwa ndi thupi omwe amalimbikitsa kukonza khungu ndi kukula kwa basal keratinocytes
- Aloe vera , chochokera ku chomera chokhala ndi anti-inflammatory and anti-acne properties
- Alpha hydroxy acid , mankhwala achilengedwe omwe amapezeka mu zipatso, mkaka, ndi nzimbe zomwe zimalimbikitsa exfoliation ndi desquamation
- Uchi , wothira mafuta omwe uli ndi alpha hydroxy acid
- Nyanja yamchere , yomwe imakhala ndi chomera chamchere chomwe chili ndi hydrocolloids zomwe zimathandiza kuchiritsa
Zolemba
Ngati nyengo yowuma makamaka makamaka m'nyengo yachisanu, humectants amatha kutunga madzi ochulukirapo kuchokera ku mbola ndikuyambitsa kuyanika msanga.
Izi ndizowona makamaka ndi maselo opangidwa ndi mavitamini monga glycerin.
Pofuna kuthana ndi izi, zowonjezera zowonjezereka zimapanga wothandizira omwe amachititsa kuti chinyontho chiwonongeke mwa kupanga mafuta kapena mankhwala ochotsera khungu pa khungu. Maofesiwa amakhala olemera komanso odzola ndipo amaphatikizapo zinthu monga:
- Mafuta amchere
- Petrolatum
- Lanolin
- Dimethicone
- Utoto wa sheya
Ngakhale pali mankhwala awiri kapena awiri omwe ali ndi humectant ndi wothandizira, anthu ena amakonda kusakaniza-ndi-match-moisturizers monga gawo lawo lokhazikika tsiku ndi tsiku. Werengani seti ya mankhwala mosamala mukasankha, ndipo nthawi zonse mugwiritsire ntchito chinyontho chodzidzimutsa pambuyo pa chinyezi cha moisturizer chifukwa cha zotsatira zabwino.
