1.Ukhetho lweizithako ezimhlophe
✏ Ukukhethwa kwezithako ezimhlophe kufuneka kuhambelane neemfuno zemigangatho yesizwe yococeko lwezithambiso, kulandele imigaqo yokhuseleko nokusebenza ngempumelelo, ukwalela ukusetyenziswa kwezithako ezingavumelekanga, kwaye kuphephe ukusetyenziswa kwezinto ezifana nemekyuri, ilothe, iarsenic, nehydroquinone.
✏ Kuphando kunye nophuhliso lwezithambiso zokwenziwa mhlophe, kuyafuneka ukuba kuthathelwe ingqalelo iindlela ngeendlela ezahlukeneyo zokuqaqamba kwebala lolusu, izinto ezahlukeneyo ezinefuthe, kunye neendlela ezahlukeneyo zokwenza i-melanin.
✏ Ukusebenzisa izithako zokwenza mhlophe enye okanye ezininzi ezineendlela ezahlukeneyo zokusebenza, ezidityaniswe neendlela ezininzi ezimhlophe, ukwenza iziphumo ze synergistic kunye nokusombulula ngempumelelo iingxaki zebala lolusu ezibangelwa yimiba emininzi.
✏ Nika ingqwalaselo ukuhambelana kweekhemikhali zezithako ezikhethiweyo zokwenza mhlophe kwaye wakhe ifomyula ekhuselekileyo, ezinzileyo, nesebenzayo yoyilo lwefomula yokwenza mhlophe.
Imizekelo yezithako ezimhlophe ezineendlela ezahlukeneyo zokwenziwa mhlophe
2.Inkqubo yokhuselo lweUV:
✏ Funxa imitha ye-ultraviolet kwaye unciphise iimpembelelo zemitha ye-ultraviolet kwi-keratinocytes, efana ne-methoxycinnamate ethyl hexyl ester, ethylhexyltriazinone, phenylbenzimidazole sulfonic acid, diethylaminohydroxybenzoyl benzoate hexyl ester, njl.
✏ Jonga kwaye usasaze imitha ye-ultraviolet, yehlisa ifuthe elicaphukisayo lemitha ye-ultraviolet kwi-epidermis, kwaye ukhusele ulusu lomntu, njengokusebenzisa isitya se-dioksidi, i-zinc oxide, njl.
I-intracellular inhibition ye-melanocytes:
Ukuthintela umsebenzi we-tyrosinase, ukunciphisa i-melanin synthesis, ukunciphisa inani le-melanin eluswini, kunye nokwenza mhlophe ulusu, njenge.arbutin,iraspberry ketone, hexylresorcinol,phenethyl resorcinol, kunye ne-glycyrrhizin.
✏ Ukunciphisa indlela yokubonisa i-melanocytes ebandakanyekayo ekulawuleni i-MITF intetho kunye nokunciphisa ukubonakaliswa kwe-tyrosinase, njenge-resveratrol, i-curcumin, i-hesperidin, i-paeonol, kunye ne-erythritol.
✏ Ukunciphisa imidibaniso yemelanin;Ukuguqula i-melanin synthesis ukuya kwi-brown melanin synthesis, ukucoca i-oxygen free radicals, kunye nokunciphisa i-melanin synthesis, njenge-cysteine, i-glutathione, i-ubiquinone, i-ascorbic acid, i-3-o-ethyl ascorbic acid, i-ascorbic acid glucoside, i-ascorbic acid phosphate magnesium kunye nezinye izinto eziphuma kwi-VC. njengoi-vitamin E derivatives

Ukhetho lweMatrix
Ifom yedosi yemveliso yindlela yokunceda ukwenza mhlophe izithako ezisebenzayo ukufezekisa ukusebenza kwazo, kwaye kungumthwali obalulekileyo.Ifom yedosi imisela i-matrix.Ukuqulunqwa kunye ne-matrix kunempembelelo ebalulekileyo ekuzinzeni kunye ne-transdermal absorption yezithako ezimhlophe.
Ukongeza ngobumfama izithako ezimhlophe kwiimveliso, ngelixa ungahoywa indibaniselwano yezithako ezimhlophe kunye nefuthe leefom zedosi kwi-absorption yabo ye-transdermal, ayinakukhokelela kukhuseleko olwanelisayo, ukuzinza kunye nokusebenza kakuhle kwemveliso.
Iifom zedosi yeemveliso ezimhlophe ikakhulu ziquka i-lotion, i-cream, amanzi, ijeli, imaski yobuso, i-oyile yokunakekelwa kwesikhumba, njl.
✏ Cream lotion: Isixokelelwano ngokwaso siqulathe i-oyile ne-emulsifier, kunye nezinye izithako ezikhuthaza ukungena nazo zinokongezwa.Ifomula inokuhambelana okukhulu.Ezinye izithako ezimhlophe kunye ne-solubility ephantsi kunye ne-oxidation elula kunye ne-discoloration ingasetyenziswa kwinkqubo ngokulungiselela ifomula.Imvakalelo yolusu ityebile, enokulungelelanisa indibaniselwano yeoli kunye ne-emulsifier ukwenza imvakalelo yolusu entsha okanye engqindilili, okanye inokongeza iiarhente ezikhuthaza ukungena ukukhuthaza ukufunxwa kwe-transdermal kwezithako ezimhlophe.
✏ Ijeli yasemanzini: i-oyile ayinayo ngokubanzi okanye i-oyile encinci, ilungele ukubeka ulusu olunamafutha, iimveliso zasehlotyeni, amanzi okuthambisa kunye nezinye iimfuno zoyilo.Le fomu yedosi inezithintelo ezithile, kwaye izithako ezimhlophe ezine-solubility ephantsi azifanelekanga ukusetyenziswa kwifomula yolu hlobo lwefom yedosi.Xa uqulunqa iimveliso, kuyimfuneko ukuqwalasela ukuhambelana kwezithako ezimhlophe kunye nomnye, kunye nezinye iimpawu.
✏ Imaski yobuso: Faka imaski yobuso engatshintshiyo ngokuthe ngqo kumphezulu wolusu ukuthambisa i-cuticle, uthintele ukuphuma kwamanzi ukuba ngumphunga, kwaye ukhawulezise ukungena kunye nokufunxa kwezithako ezisebenzayo.Nangona kunjalo, i-mask patch yobuso inendawo enkulu yoqhagamshelwano kunye nesikhumba, esenza ukuba ulusu lukwazi ukunyamezela kwaye luneemfuno eziphezulu kubumnene bemveliso.Ke ngoko, ezinye izithako ezimhlophe ezinokunyamezelana okungalunganga azifanelekanga ukuba zongezwe kwifomyula yobuso obumhlophe.
✏ I-oyile yokukhathalela ulusu: yongeza izithako ezinyibilikayo ezinyibilikayo ezimhlophe kunye ne-oyile ukwenza i-oyile yokhathalelo lolusu, okanye udibanise nefomula enamanzi ukwenza imixube emibini yedosi ephindwe kabini yobumhlophe.
Ukukhethwa kwenkqubo ye-emulsification
Inkqubo ye-Emulsification yeyona nto ixhaphakileyo kwaye isetyenziswa ngokubanzi kwizithambiso, njengoko inokuhambisa zonke iintlobo zomsebenzi kunye nezithako.Iiarhente ezimhlophe ezineepropati ezifana ne-hydrophilicity, i-oleophility, kunye nokuguquguquka okulula kunye ne-oxidation ingasetyenziswa kwiinkqubo ze-emulsion ngokusebenzisa iteknoloji yokuphucula i-formula, inika indawo enkulu yokulinganisa ukusebenza kwemveliso.
Iinkqubo ze-emulsification ezisetyenziswa ngokuqhelekileyo ziquka amanzi kwi-oyile (0/W) inkqubo, i-oyile emanzini (W/0) inkqubo, kunye ne-multiple emulsification system (W/0/W, O/W/0).
Ukukhethwa kwezinye izithako ezincedisayo
Ukuphucula ngakumbi isiphumo sokwenza mhlophe kwemveliso, ezinye izinto ezincedisayo kufuneka zikhethwe, njengeoli, i-moisturizers, i-soothing agents, i-synergists, njl.
