Pakutanga kwemwaka wezhizha, vazhinji vedu tiri kushamisika pamusoro pezuva rakanakisisa rekrimu, iro rinotarisirawo zvakatipoteredza. Kunyangwe paine vadziviriri vane zvinhu zvinogoneka, kusvika zvino chikamu chenyeredzi chakanga chisati chaunzwa: methylene yebhuruu.
Ichi chinhu, kusvika zvino chisingazivikanwi kune vakawanda, chinoshanda zvakanyanya-yakafara-spectrum UV kudzivirira mumiririri. Zvakaonekwa kuti kana zvichishandiswa pakushambira mugungwa, zvinogonawo kutarisira makorari nemhoteredzo yegungwa.
Oxybenzone inogona kusabatsira kune zvakatipoteredza
Una kutsva kutsva inoratidza kuti methylene yebhuruu inogona kunge iri iyo inotsiva yeavo vese vanoisa hupenyu hwemugungwa nekuchengetedzeka panjodzi. Mukuwedzera, inodzivirira ganda revanhu kubva kune zvinokuvadza zvinokonzerwa nemagetsi ezuva.
Muzvigadzirwa zvemazuva ano, inonyanya kushandiswa makemikari blocker ye ultraviolet rays ndeye oxybenzone. Vanotora ultraviolet B (UVB) uye ultraviolet A (UVA) mwaranzi. UVA mwaranzi inosanganiswa nekuchembera kweganda uye ine kureba kwewavelength. Nekune rumwe rutivi, mwaranzi yeUVB ndeiya ine hukama nekutsva kweganda uye ine urefu hupfupi.
Sezvineiwo, kune nyika dzakawanda dzakarambidza kushandiswa kweoxybenzone, pamwe chete nezvakatorwa, kudzivirira kukanganisa kwakashata pazvipenyu zvegungwa. Kunyangwe vatengi vachinyanya kufunga nezve sun protection factor (SPF) kudzivirira kupisa kwezuva uye pamwe nengozi matambudziko ehutano mukufamba kwenguva.
Vatsvakurudzi vakafumura rudzi rwekorari yakapfava kune yakafanana oxybenzone kana methylene blue. Izvi zvakatarisa kukura kwemhando dzakapfava dzekorari, pamwe nemhinduro dzadzo kune ese ari maviri zvikamu. Vakawana kuchena kwakanyanya uye kufa kwemakorari muXenia makorari akabatwa neoxybenzone musingasviki vhiki, nepo methylene yebhuruu isina mhedzisiro pahutano hwekorari, kunyangwe pakakwirira.
Methylene yebhuruu inonyanya kuvharira blocker
Ichi chinhu chinopa dziviriro kubva kune ultraviolet mwaranzi. Tsvagiridzo inoratidza kuti "methylene bhuruu inoshanda UVB blocker", ine zvinhu zvinonyanya kudiwa, maererano naDr. Kan Cao, munyori anotungamira uye muvambi weMblue Labs, Bluelene Skincare.
Methylene bhuruu inoratidza kunyura kwakafara kweUVB neUVA mwaranzi, inosimudzira kugadziriswa kweDNA kuvhiringika, uye haigadziri chero kukuvadza kumatombo ecoral. Vatsvagiri, vaisanganisira masayendisiti kubva kuMblue Labs neYunivhesiti yeMaryland, vakatarisa mabhenefiti ekudzivirira eUV emethylene bhuruu pakati pevadiki nevakuru, uye akaenzanisa mhedzisiro neOxybenzone.
Tsvagiridzo yakagumisa kuti bhuruu inobata UVA neUVB maranzi uye inobatsira kugadzirisa kukuvara kweDNA kunokonzerwa nemwaranzi yeultraviolet. Saka imwe sarudzo inogona kuiswa pamusoro pe classic sunscreens. Pamusoro pezvo, masayendisiti akafananidzawo methylene yebhuruu kune mamwe akajairwa ekuchengetedza ganda antioxidants akadai sevhitamini A uye vhitamini C mukugona kwayo kuderedza cellular oxidative kusagadzikana. Zvinonzi methylene bhuruu inoshanda kurwisa cell stress.
Iko kusanganiswa kwemethylene yebhuruu uye vhitamini C inogona kuve anti-aging effects, kunyanya paganda revanhu vakwegura, zvichiratidza maitiro akanaka ezvose zviri zviviri.
Tsvagiridzo nyowani inoratidza kuti methylene bhuruu inogona kunge iri chinhu chinoshanda mukati zuva nekuti haina njodzi kumatombo ecoral uye inogona kupa dziviriro yakafararira pamiranzi yeUVA neUVB.
