Izinto ezintathu zolusu olugudileyo

Inani elipheleleyo lokwaluphala lolusu:

I-UV radiation, ukufowuni

Iipesenti ezingama-70 zolusu oluvela ekufuphi

I-UV Rys ichaphazela i-collagen emzimbeni wethu, egcina ulusu lujongeka umncinci. Ukuba i-collagen iyancipha, ulusu luya kuthi lunciphise i-elasticity, ityheli, ukungqubana, ithoni yolusu olungalinganiyo, i-hyperpiment, i-chaigmetion kunye nezinye iingxaki zesikhumba.

I-spectrum yelanga yahlulahlulwe yangu-Uva kunye ne-UVB. I-UVB imitha inamaza amafutshane kwaye inokutshisa kuphela umaleko ophezulu wolusu lwethu, andikwazi ukungena nzulu kulusu; Nangona kunjalo, i-UVA ye-UVA inee-wavelength ezinde kwaye ingena kwiglasi kwaye ingene nzulu kulusu, ekugqibeleni lenza buthathaka i-collagen kwaye ikhokelela kuphuhliso lwe-wrinkles.

Ngamaxesha alula, u-UVA ukhokelela ekutshisweni, kwaye ukukhanya kwe-ultraviolet kunokwenzakalisa i-DNA yeSelfowuni, ukunciphisa umsebenzi we-fibroblast, kwaye kukhokelela kwi-synthesis eguqukayo, ukwaluphala, kunye ne-Apoptosis. Ke, i-UV yiyo yonke indawo, nokuba ilanga nokuba linelanga okanye lifu, kufuneka wenze umsebenzi olungileyo wokukhusela ilanga.

Eyona nto yesibini ibaluleke kakhulu kulusu

I-OxidaIve Free Ricals

Igama eliphambili le-radicals yasimahla yi 'ioksijini'. Siphefumla malunga ne-98 ukuya kwi-99 pesenti yeoksijini ngalo lonke ixesha siphefumla; Isetyenziselwa ukutshisa ukutya esikutyayo nokukhupha iimolekyuli ezincinci kwiiseli zethu ukuya kwi-metabolse, kwaye kukhupha amandla amaninzi ukwenza izihlunu zethu.

Kodwa mhlawumbi i-1% okanye i-2% yeoksijini inyula indlela eyahlukileyo neyingozi, le mali incinci i-oxygen, ebizwa ngokuba yi-radicals yasimahla, ehlasela iiseli zethu zasimahla. Ixesha elingaphezulu, lo monakalo ufumaneka ixesha elingaphezulu.

Eyona nto ibonakalayo yimiqondiso yokwaluphala ebonisa ulusu. Umzimba wethu unendlela yokuzikhusela elungisa umonakalo owenziwe kwiiseli zethu ngezinto zasimahla, kodwa xa ukuqokelela i-radicals yasimahla, kodwa xa iqhinga le-radicals yasimahla lingazilungisa ngakumbi kunezilolo zomzimba.

Lo mfanekiso ungentla sisizi izicubu zesikhumba somzimba wethu, unokubona ngokucacileyo ukuba i-epidermis ephezulu kwaye i-demis ye-rides iqaqambile, kunye neeseli ezivelisa i-collages, ezingumatshini wokwenza oomatshini.

I-fibroblays embindini womfanekiso yi-fibroblasts, kunye ne-spider web zijikeleze yi-collagen. I-collagen iveliswa zii-fibroblasts, kwaye ulusu lolutsha luyinethiwekhi ezintathu kunye ne-fibrobgely i-fibroblages, kunye ne-fibroblests i-fills etsala ngamandla eentsinga ukuze anike isikhumba esigcweleyo kwaye sicocekile.

Kwaye ulusu oludala, i-fibroblasts kunye ne-Coltagenting phakathi kokuchithwa kwee-fibroblays kuya kuhlala imbambano, le nto sihlala siyithetha njani isikhumba, siyicombulula njani i-oxidotion?

Ukongeza ekunikeni ingqalelo ngakumbi kwi-suncreen, sinokusebenzisa abanye ngeVitamin A, Vitamin E, i-vitamic e, i-ferulic acid, i-resveratic acid, ezinye izithako zeemveliso zonyango; Ngokwesiqhelo kunokutya iziqhamo ezinemibala eqaqambileyo kunye nemifuno eqaqambileyo, ezinjengeetamatisi, iitamatisi zityebile e Lycopene.

Inokufumana ioksijini kakuhle kwaye ikhusele uxinzelelo lwe-oxidage, unokutya ngakumbi i-broccoli, i-broccoli iqulethe i-oyile ye-istard ye-istard, ezi ziqhamo kunye nemifuno kunye nemifuno zinokukhuthaza ukumelana nesesi.

Esona sithathu sibaluleke kakhulu kulusu

Ulusu lwe-tulting

Ukupheliswa, ngokwemigaqo yobungcali, ibizwa ngokuba yindlela engaphendulwanga yi-gelycosyy gencycosyy okanye impendulo ye-melad. Umgaqo kukuba ukunciphisa iswekile kubuye kwi-protile ngokungabikho kwe-enzyme; Ukucutha iswekile iguquguquka kakhulu ziiprotein, kunye nokunciphisa iswekile kunye neeproteins ezikhoyo, iprotein, kunye nokuphendula kwakhona, okanye iminyaka emfutshane.

Iminyaka yeqela leqela elingenakuphikwa, elityheli-li-brownish, elinxulunyaniswa ne-bilografity, elinxulunyaniswa nentshabalalo ye-enzyme, kwaye yenye yezona culrits eziphambili zokwaluphala komntu. Njengoko sineminyaka yobudala, iminyaka iqokelela emzimbeni, ekhokelela ekunyukeni kobunzima beendonga zangaphakathi zemithambo yegazi, i-Elastin Metabolis ekhokelela kwi-proterings ishwankathelwe kwi-Osteoporousis ekhokelela kwizakhiwo zeproteyini zakudala, okukhokelela ekulahleni nasekuthambekeni kwe-elasticy ye-collagen kunye neentsinga ze-elastic kwi-dermis.
