1. Kutayika kwa mapuloteni mu dermis:

Collagen ndi elastin, zomwe zimathandizira khungu ndikupangitsa kuti likhale lolemera komanso lolimba.Pambuyo pa zaka 25, mapuloteni awiriwa amachepetsa mwachibadwa chifukwa cha ukalamba wa thupi la munthu, ndiyeno amachititsa kuti khungu liwonongeke;Munthawi ya kutayika kwa collagen, zomangira za collagen peptide ndi maukonde zotanuka omwe amachirikiza khungu amasweka, zomwe zimapangitsa kuti pakhale zizindikiro za khungu, atrophy, ngakhale kugwa, ndipo khungu limakhala lotayirira.

2. Mphamvu yothandizira khungu imachepa:

Mafuta ndi minofu ndi chithandizo chachikulu cha khungu, pamene kutayika kwa mafuta a subcutaneous ndi kupumula kwa minofu chifukwa cha zifukwa zosiyanasiyana monga ukalamba ndi kusowa kwa masewera olimbitsa thupi kumapangitsa khungu kutaya chithandizo ndi kugwedezeka.

3. Endogenous ndi exogenous:

Ukalamba wapakhungu umayamba chifukwa cha ukalamba wamkati komanso wakunja.Kukalamba kumabweretsa kuchepa kwa umphumphu wa khungu ndi ntchito ya thupi.Kukalamba kwamkati kumatsimikiziridwa ndi majini, ndipo sikungasinthe, komanso kumakhudzana ndi zowonongeka zaufulu, glycosylation, endocrine, etc. Pambuyo pa ukalamba, kutayika kwa minofu ya adipose, khungu kupatulira, ndi kolajeni ndi hyaluronic acid kaphatikizidwe mlingo ndi wotsika kuposa mlingo wotayika. , kuchititsa atrophic khungu kutaya elasticity ndi sagging.Kukalamba kwakunja kwa makwinya kumachitika makamaka chifukwa cha kuwala kwa dzuwa, komwe kumakhudzananso ndi kusuta, kuwononga chilengedwe, kusamalidwa kolakwika kwa khungu, mphamvu yokoka, ndi zina zotero.

4. UV:

80% ya kukalamba kwa nkhope kumayamba ndi kuwala kwa dzuwa.Kuwonongeka kwa UV pakhungu ndi njira yophatikizira, kutsatira pafupipafupi, nthawi komanso mphamvu ya dzuwa, komanso chitetezo cha khungu la pigment yake.Ngakhale khungu lidzayambitsa njira yodzitetezera ikawonongeka ndi UV.Yambitsani ma melanocyte mu basal wosanjikiza kuti apange kuchuluka kwakuda ndikuwanyamula kupita pamwamba pa khungu kuti atenge kuwala kwa ultraviolet, kuchepetsa kuwonongeka kwa cheza cha ultraviolet, koma kuwala kwina kwa ultraviolet kudzalowabe dermis, kuwononga makina a collagen, hyaluronic acid kutaya, zotanuka CHIKWANGWANI atrophy, ndi kuchuluka kwa ma free radicals, kuchititsa suntan, kumasuka, youma ndi akhakula khungu, ndi makwinya akuya minofu.Choncho, sunscreen iyenera kuchitidwa chaka chonse.

Mwachitsanzo, mphamvu yokoka, chibadwa, kupsinjika maganizo, kuwala kwa dzuwa ndi kusuta kumasinthanso khungu, ndipo potsirizira pake kumapangitsa kuti khungu liwonongeke, zomwe zimabweretsa kumasuka.

Chidule:

Khungu limakalamba chifukwa cha zinthu zingapo.Pankhani ya kasamalidwe, tiyenera kuyamba ndi chikhalidwe cha khungu ndi zifukwa zokalamba, ndikusintha mwasayansi kasamalidwe.Makwinya enieni akapangidwa, zimakhala zovuta kuti mankhwala osamalira khungu achotsedwe bwino.Ambiri a iwo ayenera kuphatikizidwa ndi kasamalidwe kazida zokongolakuchita pa dermis kukwaniritsa makwinya kuchotsa zotsatira, mongaMTS mesoderm mankhwala, mawayilesi pafupipafupi, singano yowunikira madzi, laser, kudzaza mafuta, poizoni wa botulinum, ndi zina zambiri.
