Abantu emhlabeni bathanda i-J. Lo, esanda kuqatshulwa yilanga, ekhanya njengomuntu olandelayo—kodwa asiyithandi ingozi ehambisana nelanga ehambisana nokuthola lokhu kukhanya. Faka ubuhle bomuntu ozishintshayo i-tanner. Kungakhathaliseki ukuthi iphuma ebhodleleni noma i-spray ese-salon, ungaqiniseka ukuthi ifomula iqukethe i-dihydroxyacetone. Leli gama limnandi impela, yingakho i-dihydroxyacetone ivame ukubizwa ngokuthi i-DHA.
I-DHA ifana ne-unicorn ezweni lezithako zobuhle ngoba, okokuqala, itholakala kuphela esigabeni esisodwa semikhiqizo, kanti okwesibili, empeleni iyisithako kuphela esingenza lokho ekwenzayo. Qhubeka ufunda ukuze ufunde ukuthi leyo mibala ye-faux tan iba kanjani.
I-DIHYDROXYACETONE
UHLOBO LWESITHAKO: Ushukela
IZINZUZO EZIPHAMBILI: Kubangela ukusabela kwamakhemikhali esikhumbeni okudala ubumnyama bamaseli ukuze abukeke ephuzi.1
UBANI OKUFANELE AYISEBENZISE: Noma ubani ofuna ukubukeka njengombala ophuzi ngaphandle kokulimala kwelanga. I-DHA ngokuvamile ibekezelelwa kahle yiningi, yize ngezinye izikhathi ingabangela i-contact dermatitis, kusho uFarber.
UNGAYISEBENZISA KANGANI: Umphumela wobumnyama we-DHA uvela zingakapheli amahora angu-24 futhi uhlala kuze kube yisonto, ngokwesilinganiso.
KUSEBENZA KAHLE NGE: Izithako eziningi ezimanzisa umzimba, ezivame ukuhlanganiswa ne-DHA emikhiqizweni yokuzishintsha umbala, ikakhulukazi ama-moisturizer nama-serum, kusho uFarber.
UNGASEBENZISI NGE: Ama-Alpha hydroxy acids asheshisa ukuqhekeka kwe-DHA; yize eyindlela enhle yokususa umbala wakho wesikhumba uma usulungile, ungawasebenzisi uma ufaka i-self-tanner.
Kuyini i-Dihydroxyacetone?
“I-Dihydroxyacetone, noma i-DHA njengoba ivame ukubizwa ngayo, iyinhlanganisela kashukela engenambala esetshenziswa kwabaningi abazithambisayo,” kusho uMitchell. Ingatholakala ngokwenziwa noma itholakale kushukela olula otholakala kuma-beet kashukela noma kumoba. Isexwayiso samaqiniso ajabulisayo: Yisithako kuphela esivunyelwe yi-FDA njengesithambisayo, kunezela uLam-Phaure. Uma kukhulunywa ngemikhiqizo yobuhle, uzoyithola kuphela kuma-self-tanner, yize ngezinye izikhathi isetshenziswa ngesikhathi senqubo yokwenza iwayini, kuphawula uMitchell.
Indlela i-Dihydroxyacetone Esebenza Ngayo
Njengoba kushiwo, umsebenzi oyinhloko we-DHA (ofundwayo kuphela) ukudala ubumnyama besikhumba okwesikhashana. Ikwenza kanjani lokhu? Sekuyisikhathi sokuba mnene futhi ube nesibindi okwesikhashana, ngoba konke kuncike ekusabeleni kwe-Maillard. Uma leli gama lizwakala lijwayelekile, kungenzeka ukuthi mhlawumbe ulizwile ekilasini lekhemistri lesikole samabanga aphezulu, noma ngenkathi ubukele i-Food Network. Yebo, i-Food Network. “Ukusabela kwe-Maillard kuyindlela yokusabela kwamakhemikhali eyaziwa nangokuthi i-non-enzyme browning—yingakho inyama ebomvu iba bomvu uma ipheka,” kuchaza uLam-Phaure.
Siyazi, kuyamangaza kancane ukuqhathanisa inyama yenkomo eshisayo ne-self-tanner, kodwa sizwe. Njengoba kukhulunywa ngesikhumba, ukusabela kwe-Maillard kwenzeka lapho i-DHA ixhumana nama-amino acid kumaprotheni amangqamuzana esikhumba, okubangela ukukhiqizwa kwama-melanoid, noma imibala ensundu, kuchaza uLam-Phaure.1 Lokhu, nakho, kudala ukubukeka okunsundu.
Kufanele kukhunjulwe ukuthi lokhu kusabela kwenzeka kuphela esikhumbeni, ungqimba oluphezulu lwesikhumba, yingakho i-self-tanner ingeyona ehlala njalo.1 Uma lawo maseli anombala ophuzi ephela, ukubukeka okumnyama kuyanyamalala. (Yingakho futhi ukukhipha i-exfoliation kuyisihluthulelo sokususa i-DHA; okwengeziwe ngalokho maduze.)
Imibuzo Evame Ukubuzwa
Ingabe i-DHA iphephile esikhumbeni?
I-Dihydroxyacetone, noma i-DHA, ivunyelwe emikhiqizweni yokuzishintsha umbala yi-FDA kanye neKomidi Lesayensi Lezokuphepha Kwabathengi le-EU.3 Ngo-2010, le nhlangano yokugcina yathi ekugxilweni okufika kumaphesenti ayi-10, i-DHA ayibeki ingozi empilweni yabathengi.4 Qaphela ukuthi i-FDA igcizelela ukubaluleka kokungavumeli i-DHA isondele ezindebeni zakho, emehlweni, noma kunoma yiziphi ezinye izindawo ezimbozwe ulwelwesi lwamafinyila.5
Ingabe i-DHA Iyingozi?
Nakuba i-FDA ivumile ukusetshenziswa kwe-DHA kuma-self-tanners nama-bronzers, isithako asivunyelwe ukudliwa—futhi kungaba lula ukugwinya i-DHA uma amehlo akho nomlomo wakho kungamboziwe kahle endaweni yokufutha i-spray tanning.5 Ngakho-ke uma unquma ukufuthwa uchwepheshe, qiniseka ukuthi uthola isivikelo esanele.
