ʻO Dihydroxyacetone no ka ʻili: ʻO ka mea hoʻonaninani palekana loa

Makemake nui ka poʻe o ke ao nei i ka ʻōlinolino maikaʻi i honi ʻia e ka lā, ʻo J. Lo, i hoʻi mai mai kahi holo moku e like me ke kanaka aʻe—akā, ʻaʻole mākou makemake i ka pōʻino o ka lā e pili ana i ka hoʻokō ʻana i kēia ʻōlinolino. E komo i ka nani o kahi mea hoʻonaninani ponoʻī maikaʻi. Inā paha mai loko mai o ka ʻōmole a i ʻole kahi pīpī i loko o ka salona, ​​hiki iā ʻoe ke maopopo loa aia ka dihydroxyacetone i loko o ka formula. He ʻōlelo piha ka inoa, ʻo ia ke kumu i kapa pinepine ʻia ai ʻo dihydroxyacetone ʻo DHA.

He ʻano unicorn ʻo DHA i loko o ke ao o nā mea hoʻonani no ka mea, ʻo ka mua, loaʻa wale ia i hoʻokahi ʻano huahana, a ʻo ka lua, ʻo ia wale nō ka mea hiki ke hana i kāna hana. E heluhelu e aʻo pono pehea e hiki mai ai kēlā faux tan.

ʻO DIHYDROXYACETONE
ʻANO O KA MEA HOʻOHUI: He kōpaʻa
NĀ PŌMAIKAʻI NUI: Hoʻoulu i kahi hopena kemika i loko o ka ʻili e hana ai i ka ʻeleʻele o nā ʻāpana no kahi hiʻohiʻona ʻeleʻele.1
ʻO WAI KA MEA E HOʻOHANA AI: ʻO kēlā me kēia mea makemake i ke ʻano o ka ʻeleʻele me ka ʻole o ka pōʻino o ka lā. Hoʻomanawanui maikaʻi ʻia ka DHA e ka hapa nui, ʻoiai hiki ke hana i ka dermatitis pili i kekahi manawa, wahi a Farber.
ʻEhia ka pinepine o ka hoʻohana ʻana: Hoʻomaka ka hopena ʻeleʻele o ka DHA i loko o 24 mau hola a mau a hiki i hoʻokahi pule, ma ka awelika.
HANA MAIKAʻI ME: He nui nā mea hoʻomaʻū, i hui pinepine ʻia me DHA i nā huahana self-tanning, ʻoiai nā moisturizers a me nā serums, wahi a Farber.
MAI HOʻOHANA ME: Hoʻolalelale nā ​​​​ʻakika Alpha hydroxy i ka haki ʻana o DHA; ʻoiai he ala maikaʻi lākou e wehe ai i kou ʻili ke mākaukau ʻoe, mai hoʻohana iā lākou i ka wā e hoʻopili ai i ka self-tanner.
He aha ka Dihydroxyacetone?
"ʻO Dihydroxyacetone, a i ʻole DHA e like me ka mea i kapa pinepine ʻia, he hui kō kala ʻole i hoʻohana ʻia i ka hapa nui o nā mea hoʻonaninani ponoʻī," wahi a Mitchell. Hiki ke loaʻa ma ke ʻano synthetically a i ʻole i loaʻa mai nā kō maʻalahi i loaʻa i nā beets kō a i ʻole ke kō kō. ʻŌlelo aʻoaʻo leʻaleʻa: ʻO ia wale nō ka mea hoʻohui i ʻae ʻia e ka FDA ma ke ʻano he mea hoʻonaninani ponoʻī, wahi a Lam-Phaure. I ka wā e pili ana i nā huahana nani, e ʻike wale ʻoe iā ia i loko o nā mea hoʻonaninani ponoʻī, ʻoiai hoʻi i kekahi manawa hoʻohana ʻia i ka wā o ke kaʻina hana waina, wahi a Mitchell.
Pehea e hana ai ʻo Dihydroxyacetone
E like me ka mea i ʻōlelo ʻia, ʻo ka hana nui a DHA (heluhelu wale nō: wale nō) ka hana ʻana i kahi ʻeleʻele pōkole o ka ʻili. Pehea e hana ai i kēia? ʻO ka manawa kēia e ʻoluʻolu a nerdy no kekona, no ka mea, pili ia i ka hopena Maillard. Inā kamaʻāina ke ʻano o ka huaʻōlelo, no ka mea ua lohe paha ʻoe iā ia ma ka papa kemika kula kiʻekiʻe, a i ʻole i ka nānā ʻana i ka Food Network. ʻAe, ʻo ka Food Network. "ʻO ka hopena Maillard kahi hopena kemika i ʻike ʻia hoʻi he browning non-enzymatic - ʻo ia ke kumu e ʻeleʻele ai ka ʻiʻo ʻulaʻula i ka wā e kuke ai," wahi a Lam-Phaure.
Ua ʻike mākou, he mea ʻē iki ka hoʻohālikelike ʻana i kahi steak sizzling me ka self-tanner, akā e hoʻolohe mai iā mākou. No ka ʻili, hana ʻia ka hopena Maillard i ka wā e launa pū ai ka DHA me nā waikawa amino i loko o nā protein o nā ʻili ʻili, e hana ana i ka hana ʻana o nā melanoids, a i ʻole nā ​​​​pigments brown, wahi a Lam-Phaure.1 ʻO kēia, ma ka huli ʻana, hana i kahi ʻano ʻeleʻele.
He mea kūpono ke haʻi ʻia ʻo kēia hopena e hana wale ʻia ma ka epidermis, ka papa luna loa o ka ʻili, ʻo ia ke kumu ʻaʻole mau loa ka self-tanner.1 Ke hemo kēlā mau hunaola i hoʻoluʻu ʻia, nalowale ke ʻano ʻeleʻele. (ʻO ia ke kumu he kī ka exfoliation i ka wehe ʻana i ka DHA; e pili ana i kēlā ma kahi manawa pōkole.)
Nā nīnau i nīnau pinepine ʻia
He palekana anei ka DHA no ka ʻili?
Ua ʻāpono ʻia ʻo Dihydroxyacetone, a i ʻole DHA, i nā huahana self-tanning e ka FDA a me ke Komite ʻEpekema o EU no ka Palekana o ka Mea kūʻai aku.3 I ka makahiki 2010, ua ʻōlelo ka hui hope loa i nā ʻano a hiki i ka 10 pakeneka, ʻaʻohe pilikia o ka DHA i ke olakino o ka mea kūʻai aku.4 E hoʻomaopopo i ka FDA e hoʻoikaika nei i ke koʻikoʻi o ka ʻae ʻole ʻana i ka DHA kokoke i kou mau lehelehe, nā maka, a i ʻole nā ​​​​wahi ʻē aʻe i uhi ʻia e nā membrane mucous.5

He mea ʻino anei ka DHA?
ʻOiai ua ʻāpono ka FDA i ka hoʻopili ʻana o DHA ma ke ʻano topical i nā self-tanners a me nā bronzers, ʻaʻole i ʻae ʻia ka mea hoʻohui no ka ʻai ʻana—a hiki ke maʻalahi ke ʻai ʻana i ka DHA inā ʻaʻole i uhi pono ʻia kou mau maka a me kou waha i loko o kahi pahu ʻaila ʻaila.5 No laila, inā hoʻoholo ʻoe e pīpī ʻia e kahi loea, e hōʻoia e loaʻa ana iā ʻoe ka palekana kūpono.
