1.Kusankhidwa kwawhitening zosakaniza
✏ Kusankhidwa kwa zopangira zoyera kuyenera kutsata zofunikira zaukhondo wadziko lonse, kutsatira mfundo zachitetezo ndi mphamvu, kuletsa kugwiritsa ntchito zinthu zoletsedwa, komanso kupewa kugwiritsa ntchito zinthu monga mercury, lead, arsenic, ndi hydroquinone.
✏ Pakufufuza ndi kupanga zodzoladzola zoyera, ndikofunikira kuganizira njira zosiyanasiyana zoyera zamtundu wa khungu, zomwe zimakhudza, komanso njira zosiyanasiyana zopangira melanin.
✏ Kugwiritsa ntchito chopangira chimodzi kapena zingapo zoyera zokhala ndi njira zosiyanasiyana zochitira zinthu, kuphatikiza njira zingapo zoyera, kuti mukhale ndi zotsatira zofananira ndikuthana bwino ndi vuto la khungu lopangidwa ndi zinthu zingapo.
✏ Samalani kukhudzana kwa mankhwala omwe asankhidwa kuti akhale oyera ndikupanga mamangidwe otetezeka, okhazikika, komanso ogwira mtima.
Zitsanzo za zosakaniza zoyera ndi njira zosiyanasiyana zoyera
2.Njira yachitetezo cha UV:
✏ Mumamwa cheza cha ultraviolet ndi kuchepetsa mphamvu ya cheza cha ultraviolet pa keratinocyte, monga methoxycinnamate ethyl hexyl ester, ethylhexyltriazinone, phenylbenzimidazole sulfonic acid, diethylaminohydroxybenzoyl benzoate hexyl ester, etc.
✏ Yang'anirani ndikumwaza cheza cha ultraviolet, kuchepetsa kukwiya kwa cheza cha ultraviolet pa epidermis, ndikuteteza khungu la munthu, monga kugwiritsa ntchito mbale ya dioxide, zinc oxide, ndi zina zambiri.
Kuletsa kwa intracellular ma melanocyte:
✏ Kuletsa ntchito ya tyrosinase, kuchepetsa kaphatikizidwe ka melanin, kuchepetsa kuchuluka kwa melanin pakhungu, komanso kuyera khungu, mongaarbutin,rasipiberi ketone, hexylresorcinol,phenethyl resorcinol, ndi glycyrrhizin.
✏ Kuchepetsa njira yowonetsera ya melanocyte yomwe imakhudzidwa pakuwongolera mawu a MITF ndikuchepetsa mawu a tyrosinase, monga resveratrol, curcumin, hesperidin, paeonol, ndi erythritol.
✏ Kuchepetsa melanin pakati; Kusintha kaphatikizidwe ka melanin kupita ku kaphatikizidwe ka melanin wa bulauni, kuchotsa ma radicals opanda okosijeni, komanso kuchepetsa kaphatikizidwe ka melanin, monga cysteine, glutathione, ubiquinone, ascorbic acid, 3-o-ethyl ascorbic acid, ascorbic acid glucoside, ascorbic acid phosphate magnesium ndi zina zochokera ku VC, komansozotumphukira za vitamini E
3.Kuletsa kwa extracellular ma melanocytes
4.Kuletsa kayendedwe ka melanin
5.Anti glycation zotsatira
Kusankhidwa kwa matrix
Mawonekedwe a mlingo wa mankhwala ndi njira yothandizira zopangira zoyera kuti zikwaniritse mphamvu zawo, ndipo ndizofunikira kwambiri. Fomu ya mlingo imatsimikizira matrix. Mapangidwe ndi masanjidwewo zimakhudza kwambiri kukhazikika ndi kuyamwa kwa transdermal kwa zosakaniza zoyera.
Kuonjezera mwakhungu zopangira zoyera kuzinthu, ndikunyalanyaza kuphatikizika kwa zopangira zoyera komanso kukhudzidwa kwa mitundu ya mlingo pamayamwidwe awo amtundu wa transdermal, sikungabweretse chitetezo chokwanira, kukhazikika, komanso kuchita bwino kwa mankhwalawa.
Mitundu ya mlingo wa zinthu zoyera makamaka imaphatikizapo mafuta odzola, kirimu, madzi, gel osakaniza, chigoba cha nkhope, mafuta osamalira khungu, ndi zina zotero.
✏ Mafuta odzola: Makinawo ali ndi mafuta ndi emulsifier, ndipo zopangira zina zolimbikitsira zitha kuwonjezeredwa. Fomula ili ndi kugwirizana kwakukulu. Zosakaniza zina zoyera zokhala ndi kusungunuka kochepa komanso kutsekemera kosavuta komanso kusinthika kwamtundu zitha kugwiritsidwa ntchito pamakina pokulitsa chilinganizocho. Khungu limakhala lolemera, lomwe limatha kusintha kuphatikiza kwa mafuta ndi emulsifier kuti lipangitse kumverera kwatsopano kapena kokhuthala, kapena kutha kuwonjezera othandizira kulowa kuti alimbikitse kuyamwa kwazinthu zoyera.
✏ Gelisi ya m'madzi: yopanda mafuta kapena mafuta ochepa, oyenera kuyika khungu lamafuta, zinthu zachilimwe, madzi odzola ndi zina zofunika pakupanga. Fomu ya mlingoyi ili ndi malire ena, ndipo zosakaniza zoyera zokhala ndi kusungunuka kochepa sizoyenera kugwiritsidwa ntchito mumtundu wa mtundu uwu wa mlingo. Popanga zinthu, m'pofunika kuganizira kugwirizana kwa zosakaniza zoyera ndi wina ndi mzake, ndi zina.
✏ Chigoba cha kumaso: Pakani chigoba chokhazikika pakhungu kuti mufewetse chotchinga, kupewa kutuluka kwa madzi, ndikufulumizitsa kulowa ndi kuyamwa kwa zinthu zomwe zimagwira ntchito. Komabe, chigamba cha chigoba cha nkhope chimakhala ndi malo akuluakulu okhudzana ndi khungu, zomwe zimapangitsa kuti khungu likhale losalolera komanso limakhala ndi zofunikira zapamwamba pa kufatsa kwa mankhwala. Choncho, zina zosakaniza whitening ndi kulolerana osauka si oyenera kuwonjezeredwa chilinganizo cha whitening chigoba nkhope.
✏ Mafuta osamalira khungu: onjezani zopangira zoyera zosungunuka ndi mafuta kuti mupange mafuta osamalira khungu, kapena phatikizani ndi madzi amadzimadzi kuti mupange mipangidwe iwiri ya zinthu ziwiri zoyera.
Kusankhidwa kwa emulsification system
Emulsification system ndiye chonyamulira chomwe chimagwiritsidwa ntchito kwambiri komanso chogwiritsidwa ntchito kwambiri muzodzola, chifukwa chimatha kupereka mitundu yonse yazinthu ndi zosakaniza. Whitening agents okhala ndi zinthu monga hydrophilicity, oleophility, ndi kusinthika kosavuta ndi makutidwe ndi okosijeni angagwiritsidwe ntchito m'makina a emulsion kudzera muukadaulo wokongoletsa chilinganizo, kupereka malo akulu ofananirako mayendedwe azinthu.
Njira zomwe zimagwiritsidwa ntchito popanga emulsification zimaphatikizapo madzi mumafuta (0/W), mafuta m'madzi (W/0), ndi ma emulsification angapo (W/0/W, O/W/0).
Kusankha zinthu zina zothandizira
Kuti mupititse patsogolo kuyera kwa zinthuzo, zopangira zina ziyeneranso kusankhidwa, monga mafuta, moisturizer, othandizira otonthoza, ma synergists, ndi zina zambiri.
