Zosintha zoyamba zikuwonekera kale zaka 30-35. Ngati wachinyamata unali wokwanira kugwiritsa ntchito kirimu chokha, tsopano ndi zovuta kuti tichite popanda masks odzola nthawi zonse: khungu limataya mchere. Zimakhala zovuta, zowonongeka, zopanda kubwezeretsedwa, zimatha kutaya. Pali makwinya, ndipo tsitsi lokongola limatikondweretsa kupatula patatha tchuthi. Chifukwa chake izi zikuchitika komanso momwe mungathetsere mavutowa, onani mu mutu wa mutu wakuti "Age amasintha khungu la nkhope."
Zimayambitsa ndi zotsatira
Ndili ndi zaka, kupanga adenosine triphosphate (ATP) m'maselo, chizindikiro cha ntchito zamagetsi ndi mphamvu zonse zakuthambo za thupi, zimachepa. Koma maselo a khungu lathu amatha kukonza zinthu zofunikira pokhapokha ngati ali ndi mphamvu zokwanira. Pakapita nthawi, magetsi amatha kuchepa. Izi zimachepetsa kuchepetsa mphamvu ya maselo, chifukwa mpweya umakhala wofunikira kwambiri pazochitika zambiri zamagetsi, kuphatikizapo kugwiritsidwa ntchito kwa mphamvu kuntchito ya selo. Kuonjezera apo, patapita nthawi, ntchito ya khungu yotchedwa skin fibroblasts imachepa - makamaka pamene ikuyamba kusamba. Koma ndizo zomwe zimabala collagen ndi elastin, chifukwa khungu limakhala lolimba ndi lolimba. Chomwe chimatchedwa "intercellular matrix" chimadwala: makwinya amaonekera ndipo "zomangamanga" za khungu zimasokonezeka.
Sayansi yamakono imadziwa njira zingapo zochepetsera zotsatira za kusintha kwa msinkhu. Choyamba, zimaphatikizapo kuphatikiza kwa mapuloteni (makamaka mapuloteni a soya) muzinthu zosamalirako: amachititsa kuti magetsi azigwiritsa ntchito maselo, amachititsa kuti mphamvu zamagetsi komanso ntchito za fibroblast zisinthe. Njira yachiwiri yothetsera cosmetology yamakono ndi hyaluronic asidi, imodzi yomwe imakhala ndi madzi okwana 500. Mpweya wotenthawu umapezeka pakhungu (mumtambo umodzi womwewo), umayambitsa kusinthika kwake ndipo umasokoneza katundu. Koma pokhala ndi msinkhu, hyaluronic acid imachepa, zomwe zimangowonjezera kusungunuka kwa maselo, komanso kuti khungu limasokonezeka. Choncho, khungu lathu limafuna mlingo woyenera wa hyaluronic acid.
Zotsatira
Mayesero amasonyeza kuti patadutsa masiku 28, kuzama kwa makwinya akulu kunachepera ndi 27%; dera lamakwinya lakuya linachepera ndi 40%; khungu linasungunuka kwambiri. Chifukwa chakuti mapuloteni a soya omwe ali m'gululi amachulukitsa kaphatikizidwe ka ATP, kuchepa kwa khungu kumakula. Ndipo imapereka mtundu wathanzi, pamwamba pake, maselo amagwira mofulumira ndipo, motero, amasinthidwa mwamsanga. Hyaluronic acid imayambitsa kaphatikizidwe ka collagen ndi elastin - chifukwa chake timayiramo asidi mu anti-aging treatment, kupititsa patsogolo khungu ndi mphamvu. Kuphatikizidwa mu kukonzekera kokha, izi ndi zowonjezera zina zimakhala zovuta. Tsopano tikudziwa kuti kusintha kwa khungu kwa nkhope kumakhala ndi zaka zingati.
