Ama-antioxidants yizinto ezivikela umuntu ezifweni ezisebenzayo zomoya-mpilo, kanye nama-radicals mahhala. Bangena emzimbeni, ngokuvamile ngokudla. Ngenxa yezindawo zayo, kungenzeka ukuthola ama-antioxidants ezithombeni.
Iqiniso lokuthi ama-antioxidants anomphumela wokuvuselela awubonakali. Kunalokho bavikele izimonyo ngokwabo ezinkambisweni ze-oxidative emoyeni. Ama-antioxidants amaningi anama-molecule amakhulu futhi akakwazi ukungena emzimbeni ngesikhumba. Ukusebenza ngokuqondile kwalezi zinto esikhumbeni futhi akuvimbeli inqubo yokuguga, ngoba kufanele ingene emzimbeni ngaphakathi.
Kuye kwafakazelwa ukuthi ama-antioxidants anethonya lokuphulukisa, unciphisa ukuvuvukala futhi udale umgoqo emisebeni ye-ultraviolet. Ngakho-ke, izindlela ezinhle kakhulu zokusebenzisa lezi zinto zilandela ama-cream, ama-sunscreens, ama-emollients asetshenziselwa isikhumba ngemuva kokubheka.
Ama-antioxidants adume kakhulu asetshenziselwa izimonyo yi-coenzyme Q10, selenium, amavithamini afana ne-A, C, E, F, i-lipoic acid, i-carotenoids (i-lycopene ne-β-carotene), i-bioflavonoids.
I-Vitamin C (okungenjalo - i-ascorbic acid) - le-antioxidant ihlakazeka emanzini. Ukutholakala kwalo ku-izimonyo kuklanyelwe ukuvikela isikhumba emiphumeleni yokukhanya kwe-ultraviolet, kuphuthuma inqubo yokuphulukisa kwamanxeba, kuthuthukisa ukukhiqizwa kwe-collagen esikhumbeni, kunciphise ukuguga.
I-Vitamin E (a-tocopherol) - ichitheka emafutheni. Elinye igama laleli vithamini yi-vitamin yobusha. Omunye wemithombo ewusizo kakhulu yale vithamini yiwoyela wegorosi amafutha, okuvame ukungezwa ezithombeni. Iqukethe le vithamini emafutheni omifino, atholakala ngokucindezela okubandayo, okusanhlamvu kanye nohlamvu oluhluma.
I-carotenoids (i-lycopene, i-β-carotene, i-retinol, njll) iphinde ichithe emafutheni. Lezi zinto ziyashesha ukuphulukiswa kwamanxeba, zivikele isikhumba kusuka ku-ultraviolet, ziqede ukoma nokucwenga isikhumba. Zinezingulube ze-orange nezibomvu zezitshalo. Bacebile ngamafutha kanye namafutha e-sea-buckthorn, izaqathe, i-dogrose, nayo ingatholakala emafutheni omnqumo.
I-Bioflavonoids (plant polyphenols), elinye igama layo - i-phytoestrogens, ngoba ihlelwe ngendlela efana ne-estrogens yabantu, kuphela izitshalo ezivela kuzo. Zitholakala eluhlaza okwesibhakabhaka, kanye nezingulube eziluhlaza zezitshalo. I-Phytoestrogens yohlobo oluthile lungaba khona njalo emithonjeni yamanzi emifino.
I-Superoxide dismutase (i-SOD)
Le enzyme iyanqanda amafomu asebenzayo oksijini. Emalungiselelweni okuzithokozisa, ama-SOD esitshalo, isilwane noma imvelaphi ye-microbial isetshenziswa. Le enzyme ingatholakala kulezi zitshalo ezilandelayo: itiye eluhlaza, i-witch hazel, i-sea buckthorn, i-chestnut yamahhashi, i-ginkgo biloba, njll.
Coenzyme Q
Le molekyu isisiza ukukhiqiza amandla ku-mitochondria (amangqamuzana wamandla eseli), inezindawo zokuvimbela i-antioxidant, futhi ivikela nokulimala kwe-oxidative ku-mitochondria. Le molekyula ingeziwe kuma-cosmetics okulwa nokuguga.
I-Vitamin F iyinhlanganisela yama-acids ama-unsaturated (i-arachidonic, linoleic, i-linolenic), esetshenziselwa kakhulu ekwakhiweni kwemikhiqizo yezitho zomzimba ezihloselwe ukondla, ukuhlanzwa kwesikhumba, ikakhulukazi uma isikhumba sithukuthele, somile, sinezibonakaliso ezicacile zokwehla. Lapho kuhlushwa ama-3-7%, le vithamini isisiza ukuqinisa imisebenzi yokuzivikela ye-epidermis, ubuyisele ukulinganisela kwe-hydrolipid, ngakho-ke isikhumba siswakanyisiwe, futhi ukuqina kwayo kukhula.
I-Panthenol (i-vitamin B5) - inemiphumela ephikisana nokuvuvukala. Yengezwa ezikhwameni ezenzelwe ukunakekelwa isikhumba esithukuthele nesicasulayo, kufaka phakathi nezinqubo zezimonyo. Kubuye kube yingxenye yezimpawu zezimoto nama-balms ezinwele, izinhlanzi zezingane kanye ne-sunscreen, njll.
I-Selenium yinto edingekayo emsebenzini we glutathione peroxidase. Esikhathini sezimonyo ngokuvamile uhlanganisa amanzi ashisayo, aqukethe selenium noma izakhi ze-selenium ne-cysteine ne-methionine. Izindlela ezinjalo zivuselela futhi zithuthukise isikhumba, ziqede ukucasuka.
