Li-antioxidants ke lintho tse sireletsang motho mefuteng e sebetsang ea oksijene, hammoho le li-radicals tsa mahala. Li kena 'meleng, hangata li e-na le lijo. Ka lebaka la thepa ea eona, ho ka khoneha ho fumana li-antioxidants ka litlolo.
Taba ea hore li-antioxidants li na le phello e tsosolosang ha e pakoe. Ho e-na le hoo ba sireletsa litlolo tsa tsona ho tsoa mekhoeng ea lik'hemik'hale moeeng. Li-antioxidants tse ngata li na le limolek'hule tse khōloanyane 'me ha li khone ho kena' meleng ka letlalo. Ho sebelisa lisebelisoa tsena ka mokhoa o tobileng le letlalo ha ho thibele ts'ebeliso ea botsofali, kaha e tlameha ho kena 'meleng ho tsoa ka hare.
E se e ntse e pakoa hore li-antioxidants li na le phello ea pholiso, ho tlosa ho ruruha le ho baka moeli oa mahlaseli a ultraviolet. Ka lebaka leo, mokhoa o motle oa tšebeliso ea lisebelisoa tsena o na le litlolo tsa litelu, li-sunscens, li-emollients tse sebelisoang letlalong ka morao.
Li-antioxidants tse tummeng ka ho fetisisa tse sebelisoang litlolo ke: coenzyme Q10, selenium, livithamine tse kang A, C, E, F, lipoic acid, carotenoids (lycopene le β-carotene), bioflavonoids.
Vithamine C (ho seng joalo - ascorbic acid) - antioxidant ena e qhibiliha metsing. Ho ba teng ha eona litlamong ho etselitsoe ho sireletsa letlalo liphellong tsa khanya ea ultraviolet, ho potlakisa mokhoa oa ho folisa maqeba, ho eketsa tlhahiso ea collagen letlalong, ho liehisa botsofali.
Vithamine E (a-tocopherol) - e qhibiliha ka mafura. Lebitso le leng la vithamine ena ke vithamine ea bocha. E 'ngoe ea mehloli ea bohlokoa ka ho fetisisa ea vithamine ena ke oli ea kokoana-hloko ea koro, e atisang ho ekeletsoa litlolo. E na le vithamine ena ka oli ea meroho, e neng e fumanoa ke ho penya ho bata, ka lijo-thollo le ho hlahisa lijo-thollo.
Carotenoids (lycopene, β-carotene, retinol, joalo-joalo) le eona e qhibiliha ka mafura. Lintho tsena li potlakisa phekolo ea maqeba, li sireletsa letlalo ho ultraviolet, li felisa ho omella le ho phunya letlalo. Li na le li-pigments tsa li-orange le tse khubelu tsa limela. Ba ruile ka oli le lihlahisoa tsa oli tsa leoatleng-buckthorn, lihoete, litloholo, hape li ka fumanoa ka oli ea palema.
Li-Bioflavonoids (limela polyphenols), lebitso la tsona le leng - phytoestrogens, hobane li rarahane ka tsela e tšoanang le li-estrogens tsa batho, ke feela limela tsa tlhaho. Li na le li-blue, hammoho le li-pigments tse tala tsa limela. Mefuta e itseng ea Phytoestrogens e batla e fumanoa lihlahisoa tsa metsi.
Superoxide dismutase (SOD)
Enzyme ena e senya mefuta e sebetsang ea oksijene. Litokisetsong tsa litlolo, li-SOD tsa limela, liphoofolo kapa likokoana-hloko li sebelisoa. Enzyme ena e ka fumanoa ho limela tse latelang: tee e tala, mohaho oa moloi, sea buckthorn, li-chestnate tsa pere, ginkgo biloba, joalo-joalo.
Coenzyme Q
Molek'hule ena e thusa ho hlahisa matla mitochondria (lisele tsa matla tsa seleng), e na le li-antioxidant properties, hape e sireletsa khahlanong le tšenyo ea lik'hemik'hale ho mitochondria. Molek'hule ena e kenyelletsoa litlolo tse khahlanong le botsofali.
Vithamine F ke motsoako oa unsaturated mafura a acids (arachidonic, linoleic, linolenic), e sebelisoang haholo ho etsa lihlahisoa tse ntle tse hloekileng, ho hloekisa letlalo, haholo-holo haeba letlalo le halefile, le omme, le matšoao a hlakileng a ho hlakola. Ha mahlaseli a 3-7% a ntse a lekanngoa, vithamine ena e thusa ho matlafatsa mesebetsi e sireletsang ea epidermis, ho tsosolosa ho lekanngoa ha hydrolipide, kahoo letlalo le kolobisitsoe, 'me elasticity ea eona ea eketseha.
Panthenol (vithamine B5) - e na le se boleloang se khahlanong le ho ruruha. E kenyelitsoe ho chelete e etselitsoeng ho hlokomela letlalo le tukang le le halefisitsoeng, ho kenyelletsa le ka mor'a mekhoa ea litlolo. E boetse e le karolo ea shampoo le lipalesa bakeng sa moriri, masea a bana le li-crise tsa letsatsi, joalo-joalo.
Selenium ke ntho e hlokahalang bakeng sa mosebetsi oa glutathione peroxidase. Hangata litlolo li eketsa metsi a mocheso, o nang le selenium kapa metsoako ea selenium e nang le cysteine le methionine. Meriana e joalo e nolofalletsa letlalo, e felisa ho halefa.
