1. Isisekelo sesayensi sezithako ezisebenzayo
Izithako ezisebenzayo zibhekisela ezintweni ezingasebenzisana namaseli esikhumba futhi zikhiqize imiphumela ethile yomzimba. Ngokwemithombo yazo, zingahlukaniswa zibe izingcaphuno zezitshalo, imikhiqizo ye-biotechnology, nezinhlanganisela zamakhemikhali. Indlela yayo yokusebenza ihlanganisa ukulawula izindlela zokubonisa amaselula, okuthinta ukubonakaliswa kofuzo, nokuguqula umsebenzi wama-enzyme.
Umgomo wokusetshenziswa kwezimonyo usekelwe ikakhulukazi ku-physiology yesikhumba. Izithako ezisebenzayo zimuncwa esikhumbeni futhi zisebenze ku-epidermis noma ungqimba lwe-dermis, zisebenzisa i-antioxidant, anti-aging, whitening neminye imiphumela. Isibonelo, i-vitamin C ifinyelela imiphumela emhlophe ngokuvimbela umsebenzi we-tyrosinase.
Ukulawulwa kwekhwalithi kuyisihluthulelo sokuqinisekisa ukuphepha nokusebenza kahle kwezithako ezisebenzayo. Kubandakanya ukuhlolwa kobumsulwa bezinto zokusetshenziswa, ukucaciswa kokuqukethwe kwesithako esisebenzayo, ukuhlola ukuzinza, njll. Amasu okuhlaziya athuthukile njenge-HPLC, GC-MS, njll. anikeza iziqinisekiso ezithembekile zokulawula ikhwalithi.
2. Ukuhlaziywa kwezithako ezisebenzayo ezijwayelekile
Izithako ze-Antioxidant ezifana ne-vitamin C, i-vitamin E,i-coenzyme Q10, njll. kunganciphisa ama-radicals mahhala futhi kubambezele ukuguga kwesikhumba. Ucwaningo luye lwabonisa ukuthi ngemva kwamasonto angu-12 okusebenzisa imikhiqizo equkethe uvithamini C, ukujula kwemibimbi yesikhumba kwehla ngo-20%.
izithako ezimhlophe zihlanganisai-arbutin, i-niacinamide, i-quercetin, njll. Lezi zithako zenza kube mhlophe imiphumela ngokuvimbela ukukhiqizwa kwe-melanin noma ukusheshisa umzimba wayo. Izivivinyo zemitholampilo zibonise ukuthi imikhiqizo equkethe u-2% we-arbutin inganciphisa indawo ye-pigmentation ngo-40%.
Izithako ezilwa nokuguga njenge-retinol, ama-peptides, ne-hyaluronic acid zingashukumisa ukukhiqizwa kwe-collagen futhi zithuthukise ukunwebeka kwesikhumba. Ucwaningo luye lwaqinisekisa ukuthi ukusebenzisa imikhiqizo equkethe i-retinol izinyanga ezingu-6 kungakhuphula ukunwebeka kwesikhumba ngo-30%.
izithako moisturizing ezifanai-hyaluronic acid, i-ceramide, i-glycerol, njll. ithuthukisa umsebenzi wokuvimbela isikhumba ngezindlela ezahlukene. Idatha yokuhlola ibonisa ukuthi imikhiqizo equkethe i-hyaluronic acid ingakhuphula umswakama wesikhumba ngo-50%.
3. Ukuthuthukiswa kwesikhathi esizayo kwezithako ezisebenzayo
Isiqondiso sokuthuthukiswa kwezithako ezintsha ezisebenzayo sihlanganisa ukukhomba okuqinile, i-bioavailability ephezulu, kanye nendlela ecacile yokwenza. Isibonelo, izithako ezisebenzayo ezisekelwe ku-epigenetics zingalawula ukubonakaliswa kofuzo kumaseli esikhumba.
I-Biotechnology idlala indima ebaluleke kakhulu ekukhiqizeni izithako ezisebenzayo. Ngokusebenzisa ubuchwepheshe obunjengobunjiniyela bezakhi zofuzo nobunjiniyela bokuvutshelwa, izithako ezinokuhlanzeka okuphezulu nomsebenzi onamandla zingakhiqizwa. Umsebenzi webhayoloji we-collagen ehlangene uphindwe kathathu kunokukhishwa kwendabuko.
Ukunakekelwa kwesikhumba komuntu siqu kuyisitayela esizayo. Ngokusebenzisa amasu afana nokuhlolwa kofuzo nokuhlaziywa kwe-microbiota yesikhumba, inhlanganisela ehlosiwe yezithako ezisebenzayo ingathuthukiswa. Ucwaningo lubonise ukuthi izinhlelo zokunakekelwa kwesikhumba komuntu siqu zisebenza kahle ngo-40% kunemikhiqizo ejwayelekile.
Izithako ezisebenzayo ziqhubezela imboni yezimonyo ibheke endleleni yesayensi nenembe kakhudlwana. Ngokuthuthukiswa kobuchwepheshe obusezingeni eliphezulu njenge-biotechnology kanye ne-nanotechnology, kuzoba khona impumelelo eyengeziwe ocwaningweni nasekusetshenzisweni kwezithako ezisebenzayo. Lapho bekhetha izimonyo, abathengi kufanele banake isimo sesayensi nesihlosiwe sezithako ezisebenzayo, babuke ngokunengqondo ukusebenza kahle komkhiqizo, futhi banake kakhulu impilo yesikhumba kuyilapho bephishekela ubuhle. Ngokuzayo, izithako ezisebenzayo ngokungangabazeki zizoletha ukuqamba okusha kanye namathuba embonini yezimonyo.
