Vanhu vari munyika vanoda kupenya kwezuva kwakanaka, J. Lo, kungobva kusvetwa nezuva kunopenya sezvakaita munhu anotevera—asi isu hatidi kukuvara kwezuva kunokonzerwa nekuwana kupenya uku. Ona runako rwemuchina weganda anozvishongedza. Ingava iri mubhodhoro kana mu-salon spray, unogona kuva nechokwadi chekuti fomura iyi ine dihydroxyacetone. Zita racho rinonaka, ndosaka dihydroxyacetone ichinyanya kushandiswa neDHA.
DHA inenge yakafanana neyunicorn munyika yezvinoshandiswa pakunaka pakuti, yekutanga, inowanikwa muchikamu chimwe chete chezvigadzirwa, uye yechipiri, ndiyo yega chinhu chinogona kuita zvainoita. Ramba uchiverenga kuti uzive chaizvo kuti tan iyoyo yenhema inozobuda sei.
DIHYDROXYACETONE
Rudzi rwechinhu: Shuga
ZVINHU ZVAKABATSIRA: Zvinokonzera makemikari muganda izvo zvinoita kuti masero asvibe kuti aonekwe seakatsvuka.1
NDIANI ANOFANIRA KUISHANDISA: Chero ani zvake anoda chitarisiko cheganda rakatsvuka risina kukuvara nezuva. DHA inowanzo bvumidzwa nevakawanda, kunyange zvazvo dzimwe nguva ichigona kukonzera dermatitis yekubatana, anodaro Farber.
UNOGONA KUISHANDISA KANGANI: Mhedzisiro yerima yeDHA inokura mukati memaawa makumi maviri nemana uye inogara kusvika vhiki, paavhareji.
ZVINOSHANDA ZVAKANAKA NE: Zvinhu zvakawanda zvinonyorovesa, izvo zvinowanzo sanganiswa neDHA muzvigadzirwa zvinozvichenesa, kunyanya zvinonyorovesa uye zvinoisa muropa, anodaro Farber.
USASHANDISE NE: Alpha hydroxy acids inokurumidza kuparara kweDHA; kunyangwe iri nzira yakanaka yekubvisa kusviba kweganda rako kana wagadzirira, usashandise paunenge uchizora self-tanner.
Chii chinonzi Dihydroxyacetone?
“Dihydroxyacetone, kana kuti DHA sezvainowanzo taurwa, ishuga isina ruvara inoshandiswa muvanhu vazhinji vanozvigadzira waini,” anodaro Mitchell. Inogona kugadzirwa nekugadzira kana kubva mushuga dziri nyore dzinowanikwa mushuga beet kana nzimbe. Yambiro inonakidza: Ndiyo yega chinhu chinotenderwa neFDA semugadziri wehuswa, anowedzera Lam-Phaure. Kana zvasvika kune zvigadzirwa zvekunaka, unoiwana chete muvanhu vanozvigadzira waini, kunyange zvazvo dzimwe nguva ichishandiswawo panguva yekugadzira waini, anodaro Mitchell.
Mashandiro anoita Dihydroxyacetone
Sezvambotaurwa, basa guru reDHA (kuverenga: chete) nderekugadzira kusviba kweganda kwenguva pfupi. Rinoita sei izvi? Yava nguva yekuti rive rakanaka uye rine simba kwekanguva, nekuti zvese zvinoenderana neMaillard reaction. Kana izwi iri richinzwika serakajairika, zvingangodaro nekuti pamwe wakarinzwa mukirasi yekemesitiri yechikoro chesekondari, kana uchiona Food Network. Ehe, Food Network. "Maillard reaction ikemikari reaction inozivikanwawo sekuti non-enzyme browning—ndosaka nyama tsvuku ikaita browns painobikwa," anotsanangura Lam-Phaure.
Tinoziva, zvinoshamisa zvishoma kuenzanisa nyama inonaka ne self-tanner, asi tinzwei. Nezveganda, Maillard reaction inoitika kana DHA ikabatana nemaamino acids mumapuroteni emasero eganda, zvichikonzera kugadzirwa kwe melanoids, kana kuti brown pigments, Lam-Phaure anotsanangura.1 Izvi, zvinoita kuti chitarisiko cheganda chionekwe sechakatsvukira.
Zvakakosha kutaura kuti maitiro aya anongoitika chete muganda, iro riri pamusoro peganda, ndosaka munhu anozvicheka-cheka asingagari kwenguva refu.1 Kana masero iwayo atsvuka apera, chitarisiko chakasviba chinonyangarika. (Ndicho chikonzero neiwo kubvisa DHA iriyo kiyi yekubvisa; zvakawanda nezvazvo munguva pfupi.)

DHA Yakachengeteka Here paganda?
Dihydroxyacetone, kana kuti DHA, inotenderwa muzvigadzirwa zvinozvichenesa neFDA pamwe neEU's Scientific Committee on Consumer Safety.3 Muna 2010, sangano rekupedzisira rakataura kuti kana paine huwandu hunosvika gumi muzana, DHA haikonzeri njodzi kuhutano hwemutengi.4 Cherechedza kuti FDA inosimbisa kukosha kwekurega DHA iri pedyo nemiromo yako, maziso, kana chero imwe nzvimbo yakafukidzwa nemukati memukati.5
DHA Inokuvadza Here?
Kunyangwe hazvo FDA yakabvumidza kushandiswa kweDHA pamusoro peganda muzvishandiso zvekudziya muviri (self-tanners) nezvinonyungudutsa (bronzers), chinhu ichi hachibvumidzwe kunwiwa—uye zvinogona kuva nyore kunwa DHA kana maziso ako nemuromo zvisina kuvharwa zvakanaka muspray tanning booth.5 Saka kana ukasarudza kupfapfaidzwa nenyanzvi, iva nechokwadi chekuti uri kudzivirirwa zvakakwana.
