Chero ani zvake anogona kukanganiswa neganda rakaoma pane imwe nguva kana imwe. Vamwe vanhu vane ganda rakaoma nekuda kwemajini avo, vamwe vanogona kutambura naro pane dzimwe nguva muhupenyu hwavo nekuda kwezvinhu zvekunze. Kuchengeta ganda rakaoma, zvakakosha kuti uzive hunhu hwayo uye uone zvinoshandiswa zvinoda kuti ugare wakanaka.

Ganda inhengo yakakura kwazvo mumuviri wemunhu sezvo ichimiririra 16% yehuremu hwayo. Inotamba mabasa akakosha mumuviri: ganda rinotidzivirira kubva pakurwisa kwekunze (kuvhunduka, kusvibiswa…), kunobatsira muviri kudzora tembiricha yayo, kutora chikamu mukugadzira vhitamini D uye mahormone uye kunotidzivirira pavari. hutachiona kuburikidza neayo immune system (inotungamirwa nekeratinocytes). Ganda redu rakarongeka mumatanho akati wandei.

Ganda inhengo yakaoma kunzwisisa yakarongeka kuita zvidimbu zvinoverengeka zvinowirirana.

• Epidermis: ndezve iyo pamusoro peganda inoumbwa nemhando nhatu dzemasero: keratinocytes (musanganiswa wekeratin uye lipids), melanocyte (maseru anopenda ganda) uye maseru e-langherans (immune system yeganda). Epidermis inoita basa rekudzivirira nekuti iri semi-inogoneka. 
• Iyo dermis, danga repakati : Inowanikwa pasi pechirwere uye inoitsigira. Iyo yakakamurwa kuita mativi maviri, iyo papillary dermis uye iyo yemeso dermis yakazara mune tsinga magumo uye elastic elastic. Aya maviri akaturikidzana ane fibroblast (ayo anogadzira collagen) uye immune maseru (histiocytes uye mast maseru). 
• L'hypoderme, pakadzika peganda : yakasungirirwa pasi pe dermis, iyo hypodermis idipose tishu, ndiko kuti kunoumbwa nemafuta. Tsinga nemidziyo yeropa zvinopfuura nemu hypodermis kuenda kune dermis. Iyo hypodermis inzvimbo yekuchengetera mafuta, inodzivirira mapfupa nekuita sechinhu chinotyisa, inochengeta kupisa uye inogadzira iyo silhouette.

Aya marara akasiyana ane 70% yemvura, 27,5% protein, 2% mafuta uye 0,5% mineral salts uye trace element.

Ganda rakaoma rudzi rweganda, seganda rine mafuta kana rakabatana. Iyo inoratidzirwa nekusunga, kutetepa uye kunoonekwa kweganda zviratidzo sekukasira, kusvuura uye kusviba ganda. Vanhu vane ganda rakaoma vanogona zvakare kuva yakanyanya kutaurwa kukwegura kweganda kupfuura mamwe (makwati akadzika). Chikonzero chikuru cheganda rakaoma ndiko kushayikwa kwemapididhi: materu akasimbisa anotadza kuburitsa sebum yakakwana yekugadzira firimu rinodzivirira paganda. Kuomarara nekugwinha kweganda kunoitikawo kana ganda rapera mvura, izvi zvinonzi kuoma kwenguva kweganda. Mubvunzo, zvekunze kurwisa senge kutonhora, kuoma mhepo, kusvibiswa, zuva, asiwo kushomeka kwemukati nekunze hydration. Zera zvakare njodzi yekuoma nekuti nekufamba kwenguva metabolism metabolism inononoka.

Ganda rakaoma nekudaro rinoda kupihwa chikafu nekunyoroveswa nemvura zvakadzika. Iyo hydration yeganda inotanga nekupa kwakanaka kwemvura. Ndosaka zvinokurudzirwa kunwa 1,5 kusvika 2 malita emvura pazuva. Pamusoro pezvo, vanhu vane ganda rakaoma vanofanira kushandisa zvigadzirwa zvekuchengetedza zuva nezuva zvakapfuma mumidziyo inotorwa nemvura, masikirwo anonyorovesa zvinhu (zvinodaidzwawo kuti Natural Moisturizing Factors kana NMF) uye lipids kuti aidye zvakadzika. 

Nyeredzi mamorekuru mukuchengetwa kweganda kwemakore akati wandei, urea ndeimwe yeZvisikwa Moisturizing Zvinhu, zvinonzi "hygroscopic" vamiririri. MaNMF anowanikwa zviripo mukati mecorneocyte (masero ari muepidermis) uye ane basa rekukwezva nekuchengetedza mvura. Mukuwedzera kune urea, kune lactic acid, amino acids, makabhohaidhiretsi uye mamineral ions (chloride, sodium uye potasium) pakati peNMFs. 

Urea mumuviri unouya kubva pakuparara kwemapuroteni nemuviri. Iyi mamorekuru inogadzirwa nechiropa uye inobviswa mune weti. Urea inowanikwa mukunyorovesa kutarisirwa kweganda ikozvino yagadziriswa murabhoritari kubva kuammonia uye carbon dioxide. Yakanyatso kubvumidzwa nemhando dzese dzeganda, urea inozivikanwa nekeratolytic yayo (inonatsa zvinyoro ganda), antibacterial uye moisturizing (inobata uye inochengetedza mvura) chiito. Nekusunga kumamorekuru emvura, urea inozvichengeta mumatanho epamusoro epidermis. Iyi mamorekuru saka inonyanya kukodzera kune ganda rine macallus, ganda rinowoneka-ganda, ganda rinotapira uye rakaoma ganda.
