Abantu ehlabathini bayayithanda into ekhazimlayo elangeni, J. Lo, ekhazimlayo emva nje kohambo oluya elwandle njengomntu olandelayo—kodwa ngokuqinisekileyo asiyithandi into yokuba umntu oza kutshisa ilanga angenza oku. Jonga ubuhle bomntu ozenzela i-tank. Nokuba iphuma ebhotileni okanye i-spray ese-salon, ungaqiniseka ukuba le fomyula ine-dihydroxyacetone. Eli gama limnandi kakhulu, yiyo loo nto i-dihydroxyacetone idla ngokubizwa ngokuba yi-DHA.
I-DHA ifana ne-unicorn kwihlabathi lezithako zobuhle kuba, okokuqala, ifumaneka kudidi olunye lweemveliso, kwaye okwesibini, yeyona nto kuphela enokwenza oko ikwenzayo. Qhubeka ufunda ukuze ufunde ukuba loo tan yobuxoki ivela njani.
I-DIHYDROXYACETONE
UHLOBO LWESITHAKO: Iswekile
IINGENELO EZIPHAMBILI: Ibangela ukusabela kweekhemikhali eluswini okudala ukuba iiseli zibe mnyama ukuze zibonakale zimnyama.1
NGUBANI OFANELE UKUYISEBENZISA: Nabani na ofuna ukubonakala ngathi umnyama ngaphandle komonakalo welanga. I-DHA idla ngokunyanyezelwa kakuhle ngabaninzi, nangona ngamanye amaxesha inokubangela i-contact dermatitis, utshilo uFarber.
UNGAYISEBENZISA KAngaphi: Isiphumo sobumnyama se-DHA sivela kwiiyure ezingama-24 kwaye sihlala ukuya kuthi ga kwiveki, ngokomyinge.
ISEBENZA KAKUHLE NGE: Izithako ezininzi ezifumisayo, ezidla ngokudityaniswa ne-DHA kwiimveliso zokuzithambisa ngokwazo, ingakumbi izinto zokuthambisa kunye ne-serum, utshilo uFarber.
MUSA UKUSEBENZISA NGE: Ii-Alpha hydroxy acids zikhawulezisa ukuqhekeka kwe-DHA; nangona ziyindlela elungileyo yokususa umbala wakho xa sele ulungile, musa ukuzisebenzisa xa uzifaka kwi-self-tanner.
Yintoni iDihydroxyacetone?
“I-Dihydroxyacetone, okanye i-DHA njengoko ibizwa njalo, yi-compound yeswekile engenambala esetyenziswa kwii-self-tanners ezininzi,” utshilo uMitchell. Ingafunyanwa ngokwenziweyo okanye ithathwe kwiiswekile ezilula ezifumaneka kwiibhithi zeswekile okanye kumoba. Isilumkiso senyani esimnandi: Sisithako sodwa esivunyiweyo yi-FDA njenge-self-tanner, wongeza uLam-Phaure. Xa kufikwa kwiimveliso zobuhle, uya kuyifumana kuphela kwii-self-tanners, nangona ngamanye amaxesha isetyenziswa ngexesha lenkqubo yokwenza iwayini, uphawula uMitchell.
Indlela iDihydroxyacetone Esebenza Ngayo
Njengoko kukhankanyiwe, umsebenzi oyintloko we-DHA (funda kuphela) kukudala ulusu lube mnyama okwethutyana. Ikwenza njani oku? Lixesha lokuba mhle kwaye ube nerdy okomzuzwana, kuba konke kuxhomekeke kwindlela iMaillard esabela ngayo. Ukuba eli gama livakala liqhelekile, kusenokwenzeka ukuba ulivile kwiklasi yekhemistri yesikolo samabanga aphakamileyo, okanye ngelixa ubukele iFood Network. Ewe, iFood Network. “IMaillard reaction yi-chemical reaction eyaziwa ngokuba yi-non-enzyme browning—yingakho i-red meat browns xa iphekwa,” ucacisa uLam-Phaure.
Siyazi, kuyamangalisa kancinci ukuthelekisa inyama yenkomo eshushu ne-self-tanner, kodwa phulaphula. Njengoko kubhekiselele kulusu, impendulo yeMaillard yenzeka xa i-DHA idibana nee-amino acids kwiiproteni zeeseli zesikhumba, nto leyo ebangela ukuveliswa kweemelanoids, okanye imibala emdaka, uLam-Phaure ucacisa.1 Oku, kudala inkangeleko yesikhumba.
Kuyafaneleka ukukhankanya ukuba le mpendulo yenzeka kuphela kwi-epidermis, umaleko ophezulu wolusu, yiyo loo nto i-self-tanner ingasebenzi ngonaphakade.1 Xa ezo seli zimnyama ziphela, ukubonakala okumnyama kuyanyamalala. (Kungenxa yoko le nto ukukhupha i-DHA kubalulekile; funda okungakumbi ngaloo nto kungekudala.)
FAQ
Ngaba i-DHA ikhuselekile kulusu?
I-Dihydroxyacetone, okanye i-DHA, ivunyiwe kwiimveliso zokuzitshisa ngokwazo yi-FDA kunye neKomiti yeSayensi yoKhuseleko lwaBathengi ye-EU.3 Ngowama-2010, le ntlangano yokugqibela yathi xa ifikelela kwi-10 ekhulwini, i-DHA ayibeki mngcipheko kwimpilo yabathengi.4 Qaphela ukuba i-FDA igxininisa ukubaluleka kokungayivumeli i-DHA isondele kwimilebe yakho, emehlweni, okanye nakweyiphi na indawo egqunywe ziinwebu ze-mucous.5
Ngaba i-DHA iyingozi?
Nangona i-FDA ivumile ukusetyenziswa kwe-DHA kwi-self-tanners nakwi-bronzers, esi sithako asivumelekanga ukutyiwa—kwaye kunokuba lula ukuginya i-DHA ukuba amehlo nomlomo wakho azigqunywanga kakuhle kwindawo yokutshiza.5 Ngoko ke ukuba ugqiba ekubeni utshizwe yingcali, qiniseka ukuba ufumana ukhuseleko olufanelekileyo.
