Cov kws kho mob dermatologists tau faib cov tawv nqaij ntev ntev rau hauv ob pawg loj.
Koj cov noob txiav txim siab txog kev laus hauv lub cev; Nws yog cov txheej txheem ntawm kev laus, piav qhia ib tus kws kho mob dermatologist ntawm lub koom haum ntawm Dermatology. Nws yog predetermined. Nws hais tias koj cov tawv nqaij maj mam thins, cell txuas ntxiv qeeb, thiab cov protein ntau xws li collagen thiab elastin txo qis, thiab cov kev hloov no feem ntau pib hauv koj nruab nrab-20s. Koj tsis tuaj yeem txwv cov txheej txheem no, tab sis koj tuaj yeem ua kom nws qeeb.
Tus ncej thib ob yog kev laus sab nraud, uas suav txog 90% ntawm cov kev hloov pauv uas peb pom hauv daim tawv nqaij laus. "Qhov no yog kev laus los ntawm lwm yam, hloov pauv tau. Sun exposure yog tus yeeb ncuab thib ib -peb hu ua "photoaging"-tab sis kev ua qias tuaj, kev noj zaub mov tsis zoo, kev ntxhov siab ntev, thiab kev ua neej tsis zoo xws li haus luam yeeb thiab tsis tsaug zog kuj ua lub luag haujlwm tseem ceeb.
Cov kev tshawb fawb tshiab tshaj tawm qhia qhov tob ntawm cov txheej txheem sab nraud 'kev nkag mus; lawv tsis tsuas yog ua rau lub ntsej muag puas tsuaj tab sis kuj ua rau cov lus teb inflammatory thiab ua kom cov cellular - qib aging.
Cov culprits ntawm qib cellular muaj xws li telomeres, senescent hlwb, thiab glycation.
Lub kiv puag ncig tiag tiag hauv kev tiv thaiv - kev tshawb fawb kev laus tshwm sim ntawm qib microscopic. Cov kws tshawb fawb tam sim no tab tom ua haujlwm los kawm txog cov txheej txheem lom neeg tshwj xeeb:
Telomere shortening: Koj tuaj yeem xav txog telomeres li cov hnab yas tiv thaiv ntawm qhov kawg ntawm cov hlua khi, tsuas yog lawv tiv thaiv chromosomes. Telomeres luv nrog txhua qhov kev faib cell. Thaum telomeres luv dhau lawm, cov hlwb tsis tuaj yeem faib mus ntxiv thiab thaum kawg muaj hnub nyoog lossis tuag. Cov kev ntxhov siab sab nraud, xws li hluav taws xob ultraviolet thiab oxidative kev nyuaj siab, ua rau kom telomere luv luv. Kev tshuaj xyuas tsis ntev los no hauv Phau Ntawv Xov Xwm ntawm Kev Tshawb Fawb Kev Tshawb Fawb tau hais tias: 'Kev tuav lub telomere ntev yog zoo li kev tswj cov tub ntxhais hluas cellular.'
Cellular Senescence: Thaum peb muaj hnub nyoog, peb lub cev sau "zombie" hlwb-cells uas tsis sib faib tab sis tsis kam tuag. Cov hlwb no tawv ncauj ciaj sia, secreting inflammatory proteins, ua puas ib ncig ntawm cov nqaij mos noj qab haus huv, thiab ua kom aging. Qhov tshwm sim ntawm senescent cell scavengers aims los tsim cov tebchaw uas muaj kev nyab xeeb tshem tawm cov hlwb ntawm daim tawv nqaij.
3. Glycation: Qhov no yog ib qho tseem ceeb heev tab sis feem ntau overlooked txheej txheem. Thaum cov ntshav qab zib nyob twj ywm siab tas li, cov piam thaj molecules khi rau cov proteins xws li collagen thiab elastin, tsim teeb meem tshiab molecules -advanced glycation end products (AGEs). Cov txheej txheem no stiffens daim tawv nqaij cov qauv txhawb nqa, ua rau nws yooj yim dua thiab elastic. "Glycation tsim ib tug ntoo khaub lig-txuas, nruj network nyob rau hauv dab tsi yuav tsum yog ib tug mos, elastic qauv," hais tias Dr. Benjamin Carter, kws tshuaj pleev ib ce. "Nws zoo li xeb ntawm scaffolding ntawm koj daim tawv nqaij." Lub teeb xiav thiab cov pa phem kuj tseem ua rau muaj kev laus.
Thaum UVB thiab UVA rays tseem yog thawj tus neeg tawm tsam sab nraud, ob qho "cov yeeb ncuab" niaj hnub no kuj tau txais kev saib xyuas.
1. High-lub zog pom lub teeb (HEV), lossis lub teeb xiav: Lub teeb xiav tsis yog los ntawm lub hnub nkaus xwb tab sis kuj tseem nyob ntawm peb lub xov tooj smartphones, khoos phis tawj, thiab ntsiav tshuaj, nkag mus tob rau hauv daim tawv nqaij. Cov kev tshawb fawb pom tias lub teeb xiav tsim cov dawb radicals, ua rau hyperpigmentation thiab muaj peev xwm ua kom cov duab nrawm dua.
2. Cov pa phem hauv huab cua: Cov teeb meem me me (PM), polycyclic aromatic hydrocarbons (PAHs), thiab lwm yam pa phem tsim cov txheej txheem oxidative kev ntxhov siab rau ntawm daim tawv nqaij, ua rau nws cov khoom tiv thaiv thiab collagen. (2020) Ib txoj kev tshawb fawb luam tawm nyob rau hauv *Journal of Cosmetic Dermatology* pom tias cov tsheb khiav ntau dua-txog huab cua muaj feem cuam tshuam nrog kev nce ntxiv hauv cov pob txha (hnub nyoog me ntsis) thiab nasolabial quav.
3. Lub puas tau - hloov pauv arsenal ntawm kev tiv thaiv - cov khoom lag luam laus tau nthuav dav los ntawm cov khoom siv tshuaj pleev ib ce mus rau qib siab - kev kho tech.
Qhov kev nkag siab ntau ntxiv ntawm biology yog cuam tshuam ncaj qha rau cov khoom lag luam thiab kev kho mob cov neeg siv khoom tuaj yeem xaiv. Lub tswv yim ntawm kev tu tawv nqaij ib txwm muaj ntawm "kev ntxuav, toning, thiab moisturizing" tau raug hloov los ntawm kev txawj ntse, kev tshawb fawb- raws li kev tu tawv nqaij.
Sunscreen yog qhov tseem ceeb ntawm txhua hnub.
Broad -spectrum sunscreens nrog SPF 30 los yog siab dua nyob rau hauv undisputed anti- riam phom kev laus. Lawv qhov kev tsim kho tshiab nyob hauv cov qauv tsim- sib zog ua kom pom tseeb, ntxiv cov tshuaj tiv thaiv antioxidants los tiv thaiv cov pa phem, thiab ntxiv cov xim hlau oxide los muab lub cev tiv thaiv lub teeb xiav.
Lub zog ntawm cov khoom xyaw tshuaj pleev ib ce: Retinoids yog tus qauv kub -vitamin A derivatives, suav nrog AHK. Retinol (Cu) thiab tshaj -cov tshuaj tiv thaiv - tuaj yeem ua kom cov cell rov ua dua tshiab, txhawb kev tsim collagen, thiab muaj ntau xyoo cov ntaub ntawv kho mob txhawb nqa lawv cov txiaj ntsig.
Vitamin C (L{0}}ascorbic acid). Ib qho antioxidant haib uas neutralizes dawb radicals tsim los ntawm UV rays thiab muaj kuab paug, thaum brightening ntawm daim tawv nqaij laus thiab txhawb collagen synthesis.
Niacinamide (Vitamin B3). Cov khoom muaj ntau- hnub qub ua haujlwm. Nws ntxiv dag zog rau daim tawv nqaij barrier, txo redness, minimizes pores, thiab inhibits kev hloov ntawm pigmentation, pab fade tsaus nti.
Decanentide 25 yog cov qauv luv luv -chain peptide uas nws qhov tshwj xeeb amino acid ib ntus ua rau nws muaj kev lom zem tshwj xeeb. Hauv kev lag luam tu tawv nqaij, nws tau siv dav hauv kev tiv thaiv - kev laus thiab kho cov khoom. Qhov no peptide txoj haujlwm feem ntau yog los ntawm nws lub peev xwm los ua cov proteins uas tshwm sim hauv daim tawv nqaij, yog li txhawb kev sib txuas ntawm collagen thiab elastin.
Glycolic Acid / Salicylic Acid. Alpha-hydroxy acids thiab beta-hydroxy acids (xws li glycolic acid thiab salicylic acid) tuaj yeem tshem tawm cov cell tuag ntawm daim tawv nqaij, ua rau kom pom tseeb, ci ntsa iab thiab txhim kho daim tawv nqaij zoo nkauj thiab lub suab.
Lub neej yav tom ntej yog Proactive thiab tus kheej: Cov lus los ntawm lub hauv ntej ntawm dermatology yog kev txhawb zog. Txawm hais tias peb tsis tuaj yeem txwv tsis pub dhau lub sijhawm, peb muaj kev tswj hwm ntau dua li qhov cuam tshuam rau peb cov tawv nqaij. "Lub neej yav tom ntej ntawm kev tiv thaiv- kev laus yog proactive, tsis rov ua dua, thiab tus kheej zoo heev. Peb tab tom hloov mus rau cov kev daws teeb meem thiab kev kho kom haum rau ib tus neeg lub caj ces, kev ua neej, thiab txawm tias daim tawv nqaij microbiome. Peb lub hom phiaj tsis yog ua kom koj zoo li hluas mus ib txhis, tab sis kom koj cov tawv nqaij muaj kev noj qab haus huv thiab ua tiav lub neej."
Nov yog qee cov ntaub ntawv yooj yim txog Decapeptide-25: Nws qhov tshwj xeeb amino acid ib ntus thiab cov qauv lom neeg muaj txiaj ntsig zoo rau kev tu tawv nqaij. Los ntawm kev khi rau ntawm daim tawv nqaij receptors, nws tuaj yeem qhib cov txheej txheem ntawm tes, txhim kho daim tawv nqaij elasticity thiab firmness. Rau cov neeg siv khoom, qhov no txhais tau hais tias qhov zoo tshaj plaws los tiv thaiv kev laus yog holistic: ib qho kev sib raug zoo, kev tshawb fawb txog kev tu tawv nqaij niaj hnub ua ke nrog kev noj qab haus huv ntawm kev noj qab haus huv, thiab lees paub tias kev tiv thaiv ntawm daim tawv nqaij yog kev nqis peev rau kev noj qab haus huv ntawm daim tawv nqaij, tsis yog qhov zoo nkauj xwb.
