Choonadi chonse chokhudza nanocosmetics

Magetsi ndi serums, zomwe zimatha kulowa mkati mwazigawo za epidermis ndikugwira ntchito kuchokera mkati, kumenyana ndi zizindikiro za ukalamba, ndi zifukwa zake ... amati, nthano? Komabe, chifukwa cha zochitika zamakono, Kodi mumakayikirabe? Ndiye tiyeni tione chomwe chiri.
Kawirikawiri pamatchulidwe a zonona, mumatha kuwerenga zolembera kuti "zigawozi zimakhudza kokha kokha mazenera a mbola." Chowonadi ndi chakuti kukula kwake kwa mamolekyumu a zinthu kumalowa mankhwala odzola kwambiri kumakhala kwakukulu poyerekezera ndi micropores mu zigawo za khungu, ndipo kotero iwo sangakhoze kudutsa patali kuposa pamwamba pa tsamba la epidermis. Ndicho chifukwa chake malingaliro abwino kwambiri a anthu agwiritsa ntchito zoposa chaka chimodzi kuti apange mankhwala odzola omwe angawafikire.

Choyamba, asayansi anapanga liposomes. Poyamba, mipira ing'onoing'onoyi, yomwe imatha kudutsa kudutsa pakati pa malo, inagwiritsidwa ntchito pa mankhwala, koma kumayambiriro kwa zaka za m'ma 1980, makampani odzola anagwiritsa ntchito mankhwalawa. Teknoloji yatsopano yakhala ikuyendera bwino pa ntchito yothana ndi kukalamba, chifukwa mipira ya liposome yomwe inadzaza ndi zothandiza kwambiri inadutsa mliri wa epidermal ndipo inagwera zigawo zakuya za khungu komwe makoswe awo amasungunuka ndipo zinthu zogwira ntchito zimathamangira ku maselo. Chifukwa cha liposomes, zinali zotheka kuonetsetsa kuti zosakaniza zosasunthika zitha kusungidwa bwino (mwachitsanzo, mofulumizitsidwa ndi mavitamini a mpweya), koma ma liposomes okha anali osakhazikika kwambiri: antchito omwe anali nawo anali ndi masamu osapitirira miyezi 12-14. Kuonjezera apo, kawirikawiri envelopu ya liposomes imasungunuka asanafike pamtunda. Pambuyo pazinthu zoyesayesa zowonjezera luso lamakono, mwachitsanzo, kunawoneka, mwachitsanzo, spherulites - mphamvu zowonongeka zamitundu yambiri, pang'onopang'ono kumasula zogwiritsira ntchito pamene zidalowa mu khungu. Komabe, nyengo yatsopano yeniyeni inangobwera kokha ndi kukula kwa sayansi ya nanotechnology.

Nkhani zazikulu
Poyerekeza ndi nanoparticles ("nanos" mumasuliridwe ochokera ku Greek - amamera), liposomes amawoneka ngati zimphona: kukula kwa nanosomes yogwiritsidwa ntchito mu zodzoladzola nthawi zambiri ndi 10-20 nm, pamene liposomes ndi 200-600 nm. Ndipo monga momwe kuwonetsedwa kwa maphunziro a asayansi a Israeli, omwe anayamba koyamba chitukuko cha nanocosmetics, kukula kochepa koteroko kumawalola iwo kuti akwaniritse chandamale_chizungu - popanda chopinga chilichonse ndi opanda malire. Pano pali nanosomes ndipo yambani ntchito yawo: amachotsa poizoni, amachititsa kuti maselo atsopano asinthidwe, azibwezeretsa, kumenyana ndi ukalamba.

Nanosomes inatsatiridwa ndi nanocomplexes - yosankhidwa mosamala zophika, mbali iliyonse yomwe inali yopangidwa ndi nanosize.

Nanopanacea kapena nano-pangozi?
Malingana ndi kafukufuku wa yunivesite ya Lancaster ku UK, zaka zaposachedwapa, maiko ambiri ovomerezeka okhudzana ndi nanoparticles amangokhala mankhwala ochepa chabe okhudzidwa ndi khungu ndi tsitsi. Kawirikawiri, opanga zodzoladzola amagwiritsa ntchito mankhwala awo omwe mamolekyu sangathe kulowa mkati mwa khungu. Komabe, pali zina - zing'onozing'ono zomwe zimatha kudutsa m'magazi ndipo zimalowa m'magazi. Iwo ndi omwe ali asayansi. Nanoparticles ambiri akukayika kwambiri - ngakhale atakhala ndi mankhwala osiyanasiyana ndi thupi kusiyana ndi mamolekyu omwe ali ofanana kwambiri.

Masiku ano palibe amene anganene mosapita m'mbali kuti nanocosmetics ndi yopanda phindu kapena, molakwika, yowopsya: kuyankha mafunso awa, zoposa chaka chimodzi kafukufuku amafunika. Akatswiri amadziwa kuti akamagwiritsa ntchito zipangizo zogwiritsira ntchito mankhwala, zimakhala zoopsa. Koma ambiri a iwo sangathe kupereka yankho losadziwika ku funso ngati pali chiwopsezo chenicheni. Ngakhale pali asayansi ambiri omwe amayerekezera nanotechnology ndi nyenyezi za Frankenstein: Maganizo abwino kwambiri a anthu sakudziwa zomwe adalenga, chifukwa zomwe zimachitika pa thupi la umunthu zikufunikiranso kuziphunzira. Motero, kafukufuku wambiri wasonyeza kuti nanoparticles ikhoza kulimbikitsa mapangidwe a zida zopanda ufulu zomwe zimawononga kapena kusintha DNA ya maselo.

Zaka zingapo zapitazo, panali deta yomwe, mwachitsanzo, ndalama za nanoparticles (zotchedwa antiseptic ndi chida chodziwika cha zinthu zambiri zodzikongoletsera ndi kukonzekera kunja kwa ntchito), zikagwiritsidwa ntchito, zingayambitse njira zosiyanasiyana, kuphatikizapo kuphwanya pa mlingo wa DNA. Ngakhale zoposa nanocosmetics, asayansi akudera nkhawa za chitetezo cha nutraceuticals ndi nanoparticles. Ndipo bungwe la "zobiriwira" kaŵirikaŵiri limalimbikitsa kuchepetsa kanthawi kogulitsidwa kwa nanocosmetics ndi zinthu zina - malinga ngati chitetezo cha ntchito yawo sichidzatsimikiziridwa mosatsimikizika.

Kuti tipewe maganizo a tsankho, zimphona zambiri zomwe sizikhala ndi chilolezo chimodzi chokha cha anthu omwe sagwiritsira ntchito mankhwalawa zimapewa kugwiritsa ntchito "chiwerengero cha" nano ", pogwiritsa ntchito njira yotchedwa" microencapsulation technology "," microparticles "kapena" microliposomes ".

Mungathe, koma mosamala?
Masiku ano, pafupifupi chakhumi cha ndalama zomwe zimagulitsidwa ndi mabiliyoni ambiri a madola omwe akugwiritsidwa ntchito ndi malonda a nanotechnology amathera pofufuza za chitetezo chawo cha thanzi la anthu ndi chilengedwe. Koma, malinga ndi asayansi ambiri, ndalama zimenezi sizinali zokwanira.

Vuto lina ndilokuti zotsatira zafukufuku sizifalitsidwa kawirikawiri.

Nakomponenty lero ikhoza kupezeka mu mapangidwe ambiri a cocktails for mesotherapy. Zatsopano zatsopano mu nanocosmetology ndi teknoloji ya Airge, yomwe imachokera ku jekeseni ya hyaluronic acid, yomwe imapindula ndi nanoparticles ya zida zogwiritsira ntchito zakudya. Pambuyo pa ndondomekoyi, kamvekedwe ka khungu kamatuluka, makwinya amachepa, kupangidwa kwa collagen ndi elastin kumawonjezeka, ndipo chofunika kwambiri, khungu limakhala losalala ndipo limakula, ndipo kuponda khungu komwe kumachitika ndi msinkhu ndi chimodzi mwa mavuto akulu omwe kuli kovuta kulimbana ngakhalenso zopambana kwambiri zomwe zimachitika mu cosmetology zamakono .

Njira ina yotchuka ndi laser nanoporphyring, yomwe imapangitsa kuti khungu limapanga khungu lachitsulo (makamaka molondola, nano-mabowo) kumayambitsa mavuto a khungu ndi makwinya, zotambasula, zotengera zowonongeka, pores.

Kulimbikitsana kumeneku kumachititsa kuti maselo asinthidwe, kupanga collagen ndi elastin, kutulutsa khungu kumadulidwa, ndipo kumakhala kochepa kwambiri.

Zokometsera ndi zinthu zina zodzikongoletsera, zomwe zimakhala zosakanizidwa sizingagwiritsidwe ntchito imodzi kapena ziwiri, koma zimapanga mbali yaikulu ya njirayi, ndizokongola kwambiri, koma zotsatira za anti-aging agent ndi nanocomplex zimakhala zofanana ndi zotsatira za opaleshoni ya pulasitiki: makwinya a zaka amatha, nkhope ya oval imatuluka. Koma, ndithudi, iwo ayenera kusankhidwa ndi katswiri dermatocosmetologist: ndi zochita zodziimira, pali mwayi waukulu kwambiri kuti muyambe kuwombera kuchokera ku kanki ndi mpheta.

Ndipo kuchokera kwa akatswiri omwe si akatswiri (ku Russia, zodzoladzola zoterezi zimanyalanyazidwa kwambiri chifukwa chakuti zimaphatikizidwa ku mfundo ya malonda a malonda) pali vuto lina kuposa zabwino.

Mbali ina ya ndalama - m'zaka zaposachedwa, chiganizo "nano" chakhala chofewa kwambiri.

Ndipo ngati chizindikirocho chimati "nanocream" kapena "nanoshampun", nthawi zambiri zimakhala za kukhalapo kwa gawo limodzi la nanosize, ndipo nthawi zina dzina ili ndi malonda. Choncho, ngati nanocosmetics imakopa chidwi chanu, bwino mupatseni makonda ndi mbiri. Ndipo onetsetsani kuti mumamvetsera dermatocosmetologists, ndikukumbutsa kuti ili ndi chida chogwiritsidwa ntchito kwambiri kuposa mankhwala odzola, kotero palibe njira yochitira popanda kuyankhulana ndi akatswiri oyenerera!
