Lintlha tse tharo tsa letlalo le tsofetseng

Karolo e 'ngoe e le' ngoe ea botsofali:

Radiation ea UV, linepe

70% ea letlalo la letlalo le simolohang ho nka setšoantšo

UV ROS e ama seliba 'meleng oa rona, e bolokang letlalo le shebahala e le monyane. Haeba molomo oa koahela, letlalo le tla fokotsa ho fokotseha, ho sesa, ho booa, ho utloahala, molumo o lekaneng, hyperpigtement, pigmentpigmentation, pigmentpigmentation, pigmentpigmentation, pigmentpigation, pigmentpigte

Letsatsi le pharalletseng la letsatsi le arotsoe Uva le UVB. Uvb mahlaseli a makhuts'oane a na le khanya ea letlalo, 'me a ka chesa leqhubu la letlalo la rona, a sa khone ho kenella hare letlalong; Leha ho le joalo, Uvas e bolelele ba uveleth 'me e kenella ka khalase le ho kenella ka har'a letlalo, qetellong ea ho hola.

Ka mantsoe a bonolo, UVB e lebisa holong, UVB e lebisa ho ho chesa, le leseli la ultraviole le ka senya DNA ea cellular, e fokotsa tšebetso ea mohatla, e lebisang ho phetisetso ea cellular, le apoptosis. Kahoo, UV e hohle, ebang ke letsatsi kapa le na le chatsi kapa maru, o hloka ho etsa mosebetsi o motle oa ts'ireletso ea letsatsi.

Li-oxidament tsa mahala tsa mahala

Lentsoe la bohlokoa la meharo ea mahala ke 'oksijene'. Re phefumoloha hoo re ka bang karolo ea 98 ho isa ho 99 ea oksine nako le nako ha re hema; E sebelisoa ho chesa lijo tseo re li jang le ho lokolla limolek'hule tse nyane bakeng sa lisele tsa rona tse futhumetseng, 'me ha ho lokolla matla a mangata ho etsa hore mesifa ea rona e sebetse.

Empa mohlomong 1% kapa 2% ea okgen e khetha tsela e fapaneng le e kotsi, oksijene ena e nyane, hangata e ne e bitsoa lisele tsa rona tsa mahala, tse tšoasang lisele tsa rona. Ha nako e ntse e tsamaea, tšenyo ena e bokellana ka nako e telele.

Matšoao a hlokoalang haholo ke matšoao a ho tsofala a hlahang letlalong. Mmele oa rona o na le mokhoa oa ts'ireletso bo lokisang tšenyo e entsoeng ho lilaki tsa rona ka lisele tsa mahala, empa ha lisele tsa mahala li ka li lokisa, letlalo le butle-butle.

Setšoantšo se kaholimo ke lisele tsa 'nete tsa letlalo, o ka bona hantle hore li-Epiredmis tsa holimo li lefifi, Dormis e bitsoa fibroblast, eo ho nang le mechini ea ho etsa methapo.

Fibroblamps bohareng ba setšoantšo ke fibroblambers, 'me web e ba potolohileng ea bona ke molomo. Mofoko o hlahisoa ke fibroblast, 'me letlalo le lenyenyane ke k'homphieutha e likarolo li tharo, e nang le fibrobolas ka matlapeng a masela ho fafatsa letlapa le felletseng le boreleli.

Mme letlalo la khale, likhokahano tsa fibrobla le kamano pakeng tsa ho arohana ha fibroblation hangata ho tla ba le botsofaling, re rarolla letlalo hape, re rarolla lesapo la letlalo khafetsa hakae?

Ntle le ho ela hloko haholo ho khanya ea letsatsi, re ka sebelisa ba bang ka Vitamin A, Vitamin E, Ferric acid, resitloana ea lihlahisoa tsa tlhokomelo ea letlalo; Hangata e ka ja litholoana le meroho e botšo haholo, joalo ka tamati, tamati e ruile ka Lycopene.

E ka monya oksijene e hantle 'me ea thibela khatello ea maikutlo, brocoli e na le karolo ea ho itšireletsa, e le hore lisele tsena li khone ho itšireletsa, litholoana tsena le meroho li ka khothalletsa ho hanyetsa sele.
