Abantu kwisi bakunda izuba ryiza ryasomwe nizuba, J. Lo, inyuma-yinyuma-yubwoko bwurumuri nkumuntu ukurikira - ariko rwose ntidukunda kwangirika kwizuba guherekeza kugera kurumuri.Injira ubwiza bwumukunzi mwiza.Byaba bivuye mu icupa cyangwa muri salon muri salon, urashobora rwose kumenya neza ko amata arimo dihydroxyacetone.Izina rwose ni umunwa, niyo mpamvu rwose dihydroxyacetone ikunze kugenda na DHA.
DHA ni nkimwe muri unicorn mwisi yibigize ubwiza muriyo, imwe, iboneka gusa murwego rumwe rwibicuruzwa, na bibiri, mubyukuri nibintu byonyine bishobora gukora ibyo ikora.Soma kugirango umenye neza uko iyo faux tan iba.
DIHYDROXYACETONE
UBWOKO BWA INGREDIENT: Isukari
INYUNGU Z'INGENZI: Bitera imiti mu ruhu itera umwijima w'utugingo ngengabuzima.1.
NINDE WAKWIYE GUKORESHA: Umuntu wese ushaka isura yumucyo utagira izuba.Farber avuga ko DHA yihanganira benshi, nubwo rimwe na rimwe ishobora gutera indwara ya dermatite.
UKUNTU USHOBORA GUKORESHA: Ingaruka zijimye za DHA zikura mugihe cyamasaha 24 kandi kimara icyumweru, ugereranije.
AKAZI KAMWE NAWE: Ibikoresho byinshi bitanga amazi, bikunze guhuzwa na DHA mu bicuruzwa byo kwikorera, cyane cyane ibibyimba ndetse na serumu, nk'uko Farber abivuga.
NTIMUKORESHE NA: Alpha hydroxy acide yihutisha gusenyuka kwa DHA;mugihe aruburyo bwiza bwo gukuraho igituba cyawe umaze kwitegura, ntukoreshe mugihe ushyiraho tanner.
Dihydroxyacetone ni iki?
Mitchell agira ati: “Dihydroxyacetone, cyangwa DHA nk'uko bikunze kuvugwa, ni isukari itagira ibara ikoreshwa mu kwisiga.”Irashobora gukomokaho cyangwa ikomoka ku isukari yoroshye iboneka muri beterave cyangwa isukari.Lam-Phaure yongeyeho ko ibintu bishimishije byerekana: Nibintu byonyine byemejwe na FDA nkuwikorera wenyine.Mitchell avuga ko ku bijyanye n'ibicuruzwa by'ubwiza, uzabisanga gusa mu kwikenura, nubwo rimwe na rimwe bikoreshwa mu gihe cyo gukora vino.
Uburyo Dihydroxyacetone ikora
Nkuko byavuzwe, imikorere yibanze ya DHA (soma: gusa) nugukora umwijima wigihe gito wuruhu.Nigute ibikora?Igihe cyo kubona neza no gutinyuka kumasegonda, kuko byose bishingiye kuri reaction ya Maillard.Niba ijambo risa nkaho rimenyerewe, birashoboka kuko ushobora kuba warabyumvise mumashuri yisumbuye ya chimie, cyangwa mugihe ureba Urusobe rwibiryo.Nibyo, Urusobe rwibiryo.Lam-Phaure abisobanura agira ati: “Imyitwarire ya Maillard ni imiti ikoreshwa kandi izwi ku izina rya brown-non-enzymatique-niyo mpamvu inyama zitukura zijimye iyo zitetse.”
Turabizi, biratangaje gato kugereranya igikoma kinini na tan-tanner, ariko utwumve.Nkuko bijyanye n'uruhu, reaction ya Maillard ibaho mugihe DHA ikoranye na aside amine muri proteyine za selile zuruhu, bigatuma habaho umusaruro wa melanoide, cyangwa pigment yumukara, Lam-Phaure abisobanura.1 Ibi na byo, bitera uruhu. isura.
Bivuga ko iyi myitwarire iboneka gusa muri epidermis, igice cyo hejuru cyuruhu, niyo mpamvu kwikorera-tanneri bidahoraho.1 Iyo selile zimaze kwangirika, isura yijimye irazimira.(Niyo mpamvu kandi exfolisiyoneri ari urufunguzo rwo gukuraho DHA; ibindi kuri ibyo mu kanya.)
Ibibazo
DHA ifite umutekano kuruhu?
Dihydroxyacetone, cyangwa DHA, yemerewe ibicuruzwa byo kwisiga ubwabyo na FDA ndetse na komite y’ubumenyi y’ubumwe bw’ibihugu by’Uburayi ishinzwe umutekano w’abaguzi.3 Mu mwaka wa 2010, umuryango wa nyuma wavuze ko mu kwibanda ku kigero cya 10%, DHA nta kibazo kibangamira ubuzima bw’umuguzi.4. Menya ko FDA ishimangira akamaro ko kutareka DHA hafi yiminwa yawe, amaso yawe, cyangwa ahandi hantu hose huzuyemo ururenda.5.
DHA Yangiza?
Nubwo FDA yemeje ikoreshwa rya DHA muburyo bwo kwisiga hamwe na bronzeri, ibiyigize ntibyemewe kuribwa-kandi birashobora koroha gufata DHA mugihe amaso yawe numunwa wawe bitapfunditswe neza mukibanza cyo guteramo spray.5. Niba rero uhisemo guterwa na pro, menya neza ko uhabwa uburinzi buhagije.
