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.
