Sechigadzirwa chakakurumbira mumunda wekuchengetedza ganda, kuchenesa ganda kwave chinhu chakakosha kune vanhu vanoda ganda rakajeka uye rinopenya, nekuda kwezvinhu zvaro zvinoshanda zvine huwandu hwakawanda uye mhedzisiro yaro. Maitiro aro ekushanda haasi chinhu chimwe chete asi anoshanda pamwe chete pamatanho akasiyana-siyana kuti aite kuti ganda rivandudzwe kubva mukati zvichienda kunze.
Panobva kugadzirwa kwemelanin, kuchenachinhu chaichozvinogona kunzi "zviri panzeve". Tora nicotinamide semuenzaniso. Inogona kudzivirira kutakurwa kwemelanin kubva kumasero ebasal kuenda kumasero e epidermal, sekunge kuisa zvipingamupinyi munzira isingadzivisiki ye "transporters" dzemelanin, zvichideredza kuiswa kwemelanin pamusoro peganda. Transimic acid inobvisa zvakanyanya ketani yekugadzira melanin nekudzivisa kushanda kwetyrosinase. Iyi nzira yekudzivirira kuchena inonyanya kukodzera vanhu vanogara vachisangana nemwaranzi ye ultraviolet kwenguva yakareba kana kuti vane mukana wekusvibiswa neganda nekuda kwekuzvimba.
Kana melanin yatoumbwa, chinhu chinochenesa chinoshanduka kuita "nyanzvi yekuchenesa". Zvinhu zvakaita semuchero acid nesalicylic acid zvinogona kukurudzira kuvandudzwa kwe stratum corneum zvinyoro nyoro uye kukurumidzisa kubviswa kwe metabolic ye keratin yekare uye marara ane melanin. Zvakafanana nekupa ganda kuchenesa kwakadzika, zvichibvumira masero matsva uye akajeka eganda kuti aonekwe, uye kugadzirisa matambudziko eganda risina kuenzana uye kuomarara uye kusviba. Panguva iyi, vhitamini C nezvinhu zvinobva mairi, zvine simba re antioxidant, hazvingogone chete kubvisa ma free radicals anokonzerwa nezvinhu zvekunze zvakaita semwaranzi ye ultraviolet uye kusvibiswa, asiwo zvinoderedza melanin yakatogadzirwa, zvichidzorera ganda kuhunhu hwaro hwepakutanga.
Kune mavara eruvara rweganda akasimba, kuchenesa mavara kune nzira chaiyo yekurova. Zvinhu zvakaita se377 nehydroquinone (zvinoshandiswa nechiremba) zvinogona kupinda mukati meganda uye kushanda zvakananga pamaganda akatoungana, zvichikurudzira kuora kwawo nekupararira kwawo. Azelaic acid haingodzivisi kugadzirwa kwemelanin chete asiwo ine simba rekudzivirira kuzvimba, ichivandudza zvakanyanya kuvezwa kwemavara mushure mekuzvimba.
Pamusoro pekuchena, hyaluronic acid, ceramide nezvimwe zvinoshandiswa mu essence zvinogonawo kuenzana nekunyorovesa nekugadzirisa, zvichivaka chipingamupinyi chine hutano cheganda. Ganda rine hutano uye rakanyorova rinogona kuratidza chiedza zviri nani uye kuratidza kupenya kwechisikigo uye kwakajeka. Pamusoro pezvo, mamwe essence ane zvinhu zvinodzivirira glycation zvakaita secarnosine nehyaluronic acid, izvo zvisingangochenese ganda chete asiwo zvinodzivirira collagen kubva glycation, zvichidzivirira ganda kuti risashanduke yero nekuda kwekukwegura.
Zvisinei, kuti kucheneswa kweganda kuwedzere kushanda, kushandiswa kwakakodzera ndiko kunokosha. Zvakanakisisa kutanga kushivirira usati washandisa, kunyanya kune zvigadzirwa zvine acid kana zvinhu zvinoshanda zvine concentration yakawanda. Mushure mekushandisa masikati, matanho akasimba ekudzivirira zuva anofanira kutorwa; zvikasadaro, mhedzisiro yekucheneswa kweganda inogona "kuparadzwa" nyore nyore nemwaranzi ye ultraviolet. Panguva imwe chete, zvakakosha kutarisisa kurambidzwa kwekusanganiswa kwezvinhu kuti udzivise kutsamwa kweganda kunokonzerwa nekusawirirana kwezvinhu. Kucheneswa kweganda hakusi chinhu chinogona kuwanikwa nehusiku humwe chete. Nekushandisa nguva dzose kwemavhiki mana kusvika masere, pamwe chete nehurongwa hwenguva dzose uye mararamiro ane hutano, munhu anogona kuwana zvinodiwa.kuchenazvinoita kuti ganda ripenye nekupenya kwakajeka uye kunopenya.
