I-Cosmetology, eqinisweni, ayifuni ngemuva kwesayensi futhi ikhula ngesivinini esisheshayo. Kodwa-ke, ezimweni eziningi, ukunikezwa kwe-cosmetology akuyona into ephawulekayo engasiza ngempela abesifazane emzabalazweni nokuguga.
Ngokwesibonelo, cabangela ukhilimu onama-liposomes, oye wakhuthazwa ngamandla emakethe yezimonyo isikhathi eside. Lokhu ukhilimu akwazi ukuthi kusho ukuthini kwabathengi. Ake sizame ukuthola ukuthi bazikhethela kanjani nokuthi bayabamba yini ukukhishwa okulandelayo kwabadayisi.
Ingabe ukukhetha kulungile?
Ukuhlanganiswa kwemikhiqizo nama-liposomes sekuvele kwandiswe kakhulu. Izinkampani zokuqamba izinkampani zikhiqiza hhayi kuphela ama-gel kanye nama-creams, kodwa futhi nobisi lwe-sol-gel, izimo ezihlukahlukene zezinwele, amakhemikhali azinwele kanye nemigqa yamadoda - ama-lotions nama-liposomes ngaphambi nangemva kokushefa.
Yeka ukuthi ungaqapheli ukuthenga, uma ukukhangisa kusuka kusikrini se-TV sithi ubungako obukhulu kakhulu be-liposomes, kalula ukungenela ezingxenyeni ezijulile ze-epidermis, ukuletha zonke izakhi kanye nama-moisturizers phakathi nendawo yeseli, ukunika amandla nokuqina.
Ngokwabo, i-liposomes ayinalutho yamaphilisi angenalutho enza indima yokuthutha futhi igcwele izinto eziphilayo ezisebenzayo kalula ngaphakathi kwamanzi.
Ngenxa yamathuba okukhiqiza, noma yimaphi amakhemikhali-amahomoni, ama-antiseptics, ama-complex complexes, ama-vithamini kanye ne-"anti-aging-aging" enzymes angafakwa ngaphakathi kwe-liposomes.
Ekuqaleni, ama-liposomes ayenziwa ukuvikela izidakamizwa ukuze angawa ngaphansi kwethonya lezici zangaphandle, ngesikhathi sokubeletha ngezijovo ezihlukahlukene, ezingxenyeni zangaphakathi ngegazi.
Ezokwelapha, ama-liposomes aqala ukusetshenziswa kusukela emakhulwini ayikhulu namakhulu ayisishiyagalolunye namashumi ayisikhombisa nanye. Kuthatha iminyaka engaba yishumi nje kuphela, futhi baqala ukuthakazelisa kumaqhawe amakhulu okuthiwa i-cosmetology, njengo-Loreal no-Christian Dior, owaqala ukuthuthukiswa kwemali egcwele, eyayihlanganisa nokuba khona kwe-taxonomy.
Imiphumela ye-liposomes kanye nokusemandleni abo kwi-cosmetology
I-Liposomes ngokwayo ayibonakali into ebaluleke kakhulu. Into ebalulekile okudingekayo kubo kungukuthi kukhona ngaphakathi okungenalutho okukuvumela ukuba uzifihle ngokwayo izinhlanganisela ezingaqiniseki ezivikelwe ezicini zangaphandle.
Abacwaningi babeka ithemba labo esikhaleni esingenalutho se-liposomes, esilondolozwe ngokuthembekile yi-membrane eqinile ngenxa yezinto ezivela ngaphandle. I-liposomes kufanele ihambisane kahle nabathwali bamakhemikhali angenamandla. Ngaphezu kwalokho, konke kwakulula kakhulu, ngoba isakhiwo segobolondo kanye nesakhiwo se-membrane yeseli sisondelene kakhulu nesakhiwo se-membrane ne-liposome, ngenxa yokuthi i-particle ye-liposome yayakhiwe ngamangqamuzana.
Kuyaziwa ukuthi ama-enzyme abhujiswa masinyane, ngisho nasendleleni engenhla ye-epidermis, uma engahlanganiswa ngokuqinile nabathwali. Futhi ukhilimu lapho izinhlamvu ezinhle zithi "Q10!" umphumela wokulenga okulindelwe, abathuthukisi ngeke bawalethe.
Okufanayo kusebenza ku-vitamin E, enye ye-antioxidants enamandla kunazo zonke, enomphumela omuhle kakhulu wokulwa nokuguga ngenxa ye-neutralization yama-radicals yamahhala, okuyiyona eyimbangela enkulu yenqubo yokuguga kwe-cell. Ngaphansi kwesenzo se-oksijeni, i-vitamin E i-oxidized kweso. Ngakho ngesikhathi sokusebenza ukhilimu odwetshiwe, oqukethe i-vitamin E, izinguquko zayo ze-vitamin saturation.
Isithwali senethiwekhi esinjalo sisetshenziswe abaningi iminyaka engamakhulu amaningana, kodwa ukusesha ngaleso sikhathi akuphumelelanga. Izinto eziyodwa ziyi-inert ye-chemistry, ezinye zazingenakho iphunga elimnandi kunazo zonke, elingenakuqedwa ngisho nangempepho enamandla kunazo zonke, izinto zesithathu zivele ziqhume ngokushesha lapho zixhumana kancane nomoya.
Ithemba lahlala kuphela kuma-liposomes kanye neqiniso lokuthi ipulasitiki yabo yanele ukungena emigqeni ejulile ye-epidermis. Kungakhathaliseki ukuthi ukhilimu onama-liposomes, izinethemba zabathengi nabakhiqizi ziqinisekisa yini?
Isenzo sezinganekwane nge-liposome
Ngenxa yezobuchwepheshe zanamuhla zokukhiqiza, kwaba khona ukuthola izinhlayiya zibe ngu-0.1 microns ngobukhulu. Kodwa ngokuvamile ubukhulu obujwayelekile bama-liposomes buvela kumamitha angu-0.2 kuya ku-0.6. Zama ukukhumbula le nombolo. Isikhumba esingenalutho sinesayizi ye-pore ka-0.019 micron. Yenza umbuzo ozwakalayo - futhi kanjani, empeleni ama-liposomes, amakhulu amakhulu, angangena esikhumbeni? Yeka ukuthi i-liposome inkulu kakhulu kangakanani, ingabe izingqimba ze-epidermis zihamba ngaphandle kokuvinjelwa?
Abathuthukisi abakhiqiza izindlela zokuzithokozisa ngama-liposomes, bakholelwa ukuthi lokhu kungenxa yokudonswa okuthile kwesakhiwo se-liposome ngenkathi sidlula ama-microcapillaries.
Lokhu kubonakala okuthakazelisayo. Ukuphihliza nokukhubazeka, i-particle iyangena lapho idinga khona. Kodwa kuze kube manje lokhu akuqinisekisiwe ngumthombo owodwa olusemthethweni.
Isivimbela esikhumbeni sethu singakwazi ukunqoba kalula inombolo encane yama-liposomes.
Amanye ama-creams afundiswa ngaphansi kwe-microscope ye-electron. Izifundo zibonisile ukuthi azikho ama-liposomes nhlobo, noma ziye zahlakazeka kakhulu, ukuthi azibonisi noma yimaphi umphumela oyifunayo, noma zihlanganiswe ngokuphelele kumuntu oyedwa.
Lezi zinsiza zingathinta isikhumba, kodwa futhi ukuthi akufanele ukuthembela ekukhangiseni. Umphumela ofanayo ukhiqizwa yi-emulsion evamile noma ukhilimu ongafana ne-gel.
Ihlala idinga eyodwa kuphela. Ama-liposomes angena esikhumbeni sethu, echotshoziwe kakhulu, kodwa okuqukethwe kwangaphakathi akusekelwe, okwenziwe abakhiqizi.
Faka ukungenelela kwesikhumba nama-lecithini, okubhekisela ezintweni ezisebenzayo. Zikhona ezikhathini zeqanda. Ngakho-ke, izidakamizwa eziqukethe i-yolk, hhayi ezimbi kunokuba zikhangiswe, zingase zibe ngcono, ngoba intengo yabo ingaphansi kakhulu.
Futhi into eyodwa ngaphezulu. Kukhona inkolelo yokuthi phakathi nokuguga kwesikhumba amangqamuzana amangqamuzana ekhanda abo aqina, futhi ama-liposomes angawalungisa la maseli. Kodwa-ke, akekho owayengakufakazela. Amaseli amadala anesisindo esifanayo sekhanda njengamasha.
Kuhlala ukubuza - kuthiwani ukubuyisela?
