Malebela a Tlhokomelo ea Letlalo——Lintho Tse Amang ho Thella ha Letlalo

Elastin ea motho e entsoe haholo-holo ho tloha morao ho embryonic ho ea pele ho nako ea lesea, 'me hoo e ka bang ha ho elastin e ncha e hlahisoang nakong ea motho e moholo. Lithapo tsa elastic li na le liphetoho tse fapaneng nakong ea botsofali le ho etsa lifoto.

1. Bong le litho tse fapaneng tsa 'mele

Khale koana ka 1990, litsebi tse ling li ile tsa etsa liteko baithaopi ba 33 ho ithuta ho saroloha ha letlalo likarolong tse 11 tsa ’mele oa motho.

E bontša hore elasticity ea letlalo e fapane haholo pakeng tsa likarolo tse fapaneng; athe ha e le hantle ha ho na phapang e kholo lipakeng tsa batho ba bong bo fapaneng

Elasticity ea letlalo e fokotseha butle-butle ka lilemo.

2. Lilemo

Ka lilemo tse ntseng li eketseha, letlalo la botsofali la endogenous ha le fokotsehe ebile le bonolo ho feta letlalo le lenyenyane, 'me marang-rang a marang-rang a marang-rang a senyeha' me a fokotseha, a iponahatsa e le ho batalatsa ha letlalo le wrinkles e ntle; botsofaling bo sa feleng, eseng feela Fibrous Degradation ea likarolo tsa ECM, empa hape le ho lahleheloa ke likhechana tse ling tsa oligosaccharide. LTBP-2, LTBP-3, le LOXL-1 kaofela li ne li laoloa, 'me LTBP-2 le LOXL-1 li phetha karolo ea bohlokoa ho laola le ho boloka fibrin deposition, kopano le sebopeho ka ho tlama fibulin-5. Li-perturbations tse amanang le factor expression li hlaha e le mekhoa ea ho eketsa botsofali bo sa feleng.

3. Lintlha tsa tikoloho

Tšenyo ea mabaka a tikoloho letlalong, haholo-holo ho etsa lifoto, tšilafalo ea moea le lintlha tse ling li 'nile tsa lebisoa tlhokomelo butle-butle, empa liphello tsa lipatlisiso ha li hlophisehe.

Letlalo la ho etsa lifoto le khetholloa ke ho fetola le ho fetoha ha catabolic le anabolic. Letlalo le bonahala le le mahlahahlaha le le sosobane ka ho tebileng ka lebaka la ho lahleheloa ke li-microfibrils tse nang le fibrillin tse ngata sebakeng sa epidermis-dermal junction, elastin degeneration, empa habohlokoa le ho feta, ho kenngoa ha lintho tsa chaotic elastin sebakeng se tebileng sa dermis, mosebetsi oa elastin o amehile.

Tšenyo ea sebopeho sa likhoele tse rekerehang tsa letlalo e ke ke ea etsolloa pele motho a le lilemo li 18, 'me tšireletso ea UV e bohlokoa nakong ea kholo. Ho ka 'na ha e-ba le mekhoa e' meli ea mahlaseli a mahlaseli a letsatsi: likhoele tse thellang li senyeha ke elastase e patiloeng ke lisele tse pota-potileng kapa tse khantšitsoeng ke UV, 'me likhoele tse rekelitsoeng li kobehile nakong ea ts'ebetso ea synthesis; li-fibroblasts li na le phello ea ho khothaletsa likhoele tse otlolohileng ho boloka linearity. Phello e ba e fokolang, e fellang ka ho kobeha.— Yinmou Dong Khatiso ea indasteri ea lik'hemik'hale, 158-160

Ts'ebetso ea phetoho ea elasticity ea letlalo e ka 'na ea se ke ea bonahala ka ho lekaneng mahlong a hlobotseng,' me re ka sebelisa setsebiletlalo la ho hlahloba letlalohlokomela esita le ho bolela esale pele phetoho ea letlalo nakong e tlang.

Ka mohlala,ISEMECO or Resur Skin Analyzer, ka thuso ea mabone a setsebi le k'hamera e hlalosang boemo bo phahameng ho bala boitsebiso ba letlalo, ho kopantsoe le algorithm ea ho hlahloba AI, e ka shebella lintlha le ho bolela esale pele ka liphetoho tsa letlalo.
