Kuteteza ndi thanzi la khungu ndilofunika kwambiri chipolopolo chodziwika bwino, chomwe chimapangidwa pamwamba pa khungu chifukwa cha kusakaniza komwe kumapangidwa ndi sebaceous glands kusungunuka, thukuta, ndi khululu kamoyo wawo pakhungu la mabakiteriya - epidermal staphylococci. Koma zimasokonezedwa ndi kuwala kwa dzuwa, zodzoladzola, kutukuta kwambiri komanso zakudya zosiyanasiyana.
Alpha hydroxy acids.
Kawirikawiri asidi ambiri m'mapangidwe ndi alpha hydroxy acid.
Gululi limaphatikizapo zipatso zamchere - mandimu, apulo, tartaric, lactic ndi glycolic. Zakudya izi zimapezeka mu zodzoladzola zambiri ndi katundu. Pogwiritsa ntchito mankhwala odzola komanso moyenera, amawotcha khungu, amawathira, amachepetsa kuwala kwa khungu, komanso amawonjezera zowonjezera zowonongeka.
Pamwamba pa khungu nthawi zonse anapangidwa "guluu" - mtundu wochuluka wa maselo akufa a epidermis. Mankhwala oyenera a alpha hydroxy acids amawononga "gululi", ndipo amachititsa khungu kukhala losalala komanso losalala. Zotsatira zake, zikopa zakufa zakufa zimachotsedwa pamtunda, kuti zodzoladzola zilowe mkati mwa zikopa za khungu, zomwe zimapangitsa kuti zitheke. Ngati khungu silingagwirizane, limakhala losalala ndipo likuwoneka kuti silikuyenda bwino, kugwiritsa ntchito zodzoladzola ndi alpha hydroxy acids kudzapereka zotsatira zabwino.
Ngakhale kuti mawonekedwe ofanana ndi maselo amapezeka ku alpha hydroxy acids, amasiyana mosiyanasiyana ndi zotsatira za mavuto osiyanasiyana a khungu. Mwa alpha hydroxy acids, omwe amapezeka kwambiri ndi glycolic, citric, malic ndi lactic acid zomwe tatchula pamwambapa.
- Glycolic acid.
Chofala kwambiri pakati pa alpha hydroxy acids ndi glycolic acid. Amapangidwa kuchokera ku nzimbe kapena amapezeka mwachangu, mwa kaphatikizidwe. Ndizothandiza kwambiri chifukwa cha kukula kwake kwa mamolekyulu, zomwe zimachititsa kuti khungu lilowe mosavuta.
Glycolic acid amayeretsa bwino khungu la maselo akufa, amathandiza kuchotsa ang'onoang'ono makwinya ndi ziphuphu zamchere, normalizes ntchito ya glands yokhala ndi sebaceous. Imodzi mwa ubwino waukulu wa asidiyi ndi mphamvu yake yoimiritsa mtundu wa khungu, kuunika mitundu yosiyanasiyana ya pigment, kuchepetsa khungu, ndipo, ngati chothandizira, imapangitsa kuti zinthu zina zodzikongoletsera zizikhala bwino. Zimaganiziridwa kuti glycolic acid, yomwe imalowa mkati mwachangu, imathandizira kupanga collagen.
- Citric asidi.
Citric asidi ndi antioxidant yamphamvu kwambiri, kotero kuti, monga glycolic acid, imathandiza kupanga collagen mu dermis layer. Kuonjezera apo, asidi awa amachepetsa ukalamba wa khungu, kuchotsa mawanga a pigment. Citric asidi amapezeka kwambiri mu zipatso za citrus.
- Lactic asidi.
Pofewetsa khungu, lakuda khungu, akatswiri a dermatologists nthawi zambiri amagwiritsa ntchito lactic asidi omwe ali mumkaka, omwe ali ndi mphamvu zowonetsera ndi kuchepetsa khungu. Madzi a Lactic amakhalabe ndi chinyezi pakhungu, amachotsa khungu lakufa pamwamba pake ndipo amachititsa kuti zinthu zina zowonongeka zitheke.
- Apple acid.
Mankhwala a apulosi amapezeka mu mphesa zobiriwira ndi maapulo. Chifukwa cha mphamvu yake yowonjezera kutuluka kwa mpweya ku ziphuphu, nthawi zambiri amagwiritsidwa ntchito pochiza matenda monga fibromyalgia. Mankhwala a apulosi amagwiritsidwa ntchito popanga zodzoladzola zamankhwala.
Kuphatikizana kolondola kwa chilengedwe cha asidi-m'munsi mwa khungu ndi kukhalapo kwa zidulo mu wothandizira zodzoladzola ndi chinthu chachikulu chomwe chimakhudza mphamvu ya zodzoladzola pa khungu. Ngati mumagwiritsa ntchito zodzoladzola moyenera, ndiye kuti alpha hydroxy acids yothandiza pakhungu sikungayambitse mkwiyo ndipo sichidzawotchera.
Amino acid.
Peptides ndi mtundu wa unyolo, womangidwa ndi amino acid - njerwa zamagetsi za thupi. Mndandandawu uli ndi pang'ono za amino acid zomwe zimagwirizanitsidwa palimodzi, chifukwa cha zibwenzi za peptide.
Ndili ndi msinkhu, khungu limasiya kutaya kwake koyamba. Izi zimachitika chifukwa cha kuchepa kwa ntchito ya maselo apadera omwe amapanga collagen ndi elastin - zomwe zimatchedwa fibroblasts. Pambuyo pa zaka 40, pali kuchuluka kwa makwinya, monga chaka chilichonse zomwe collagen zachepetsedwa ndi 1%. Amino zidulo zimathandiza kusungunuka ndi ubwana wa khungu, zomwe zimachititsa kuti collagen ndi elastin zikhale ndi fibroblasts.
Amino acids ndi abwino kwa khungu lirilonse, chifukwa silinakhudze chilengedwe cha asidi. Matenda ambiri a khungu amathetsedwa pogwiritsira ntchito zodzoladzola zotsutsa, zomwe zili ndi amino acid.
Zida zina zothandiza.
- Alpha-lipoic asidi amachepetsa kukalamba, kulowa mkati mwazitali kwambiri pakhungu, kuchotsa maselo ofooketsa komanso owopsa a maselo a cytokine. Alpha-lipoic acid imasungunuka m'madzi ndi mafuta, ndi antioxidant yothandiza.
- Salicylic acid imagwiritsidwa ntchito pochiza mavala ndi exfoliation ya khungu louma.
- Vitamini C, pokhala antioxidant, monga ascorbic acid imathandiza kuti khungu liwunikire.
- Ellagic amachimake m'makono odzola amachepetsera maonekedwe ndi maonekedwe a misinkhu ya zaka, kukhala chilengedwe chobadwa.
- Linoleic acid imapangitsa khungu louma ndi lowonongeka. Ndi gawo la kuchepetsa emulsions.
- Hyaluronic acid imagwiritsidwa ntchito ngati chimbudzi chokhala ndi madzi ambiri.
- Poly-hydroxy-acid: monga ena hydroxy-gulu acids, ndi othandiza kwambiri, koma mwachikondi amakhudza khungu.
