Mitundu yosiyanasiyana ya madontho ndi chithandizo chawo
Pamsinkhu uliwonse mutha kuwona mawanga akuda akuwonekera pakhungu lanu. Kusakwanira kwa timadzi ta m'thupi, dzuwa, mimba…kodi matenda a mtundu uwu amachokera kuti? Kodi kuchitira iwo? Mafotokozedwe.
Onaninso kugula kwathu: Njira 6 zothandiza kwambiri zothana ndi mdima
Pali unyinji wa mawanga. Zina mwa izo, ndi kobadwa nako mawanga, zomwe zimakhala zovuta kulowererapo. Zomwe zimadziwika bwino ndi mabala kapena ephelids, mawanga a ku Mongolia kumbuyo ndi matako a ana omwe ali ndi khungu lakuda kapena lakuda, ndi angiomas. Ena mwa mawangawa amazimiririka pakapita nthawi.
Komabe, mitundu ina ya mawanga imatha kuwoneka m'moyo. Kuti amvetsetse chifukwa chake, munthu ayenera kukhala ndi chidwi ndi njira yopaka utoto pakhungu. Melanocyte ndi selo lomwe limapanga melanin ndikugawa ku keranocytes. (maselo omwe amaphimba khungu). Tikakhala ndi melanin wambiri, khungu lathu limakhala lakuda komanso lotetezedwa. Khungu lakuda kapena lakuda ndilochepa kwambiri lokhala ndi melanoma. Koma amakhudzidwanso kwambiri ndi vuto la mtundu wa pigmentation chifukwa amapanga melanin yambiri.
Kupanga melanin kumalakwika
Hyperpigmentation imatha kulumikizidwa ndi a kuwonongeka kwa melanocyte mothandizidwa ndi chinthu choyambitsa zinthu monga kuwala kwa UV, mahomoni kapena mankhwala osokoneza bongo, kapena kuwonjezeka kwa ma melanocyte m'dera lokhazikika. Zotsatira : melanin amaunjikana mopitirira muyeso m'malo ena akhungu kuti awononge ena ndipo mawanga amawonekera. Mankhwala ena omwe amagwiritsidwa ntchito pakhungu amathanso kuyambitsa mawanga ngati akhudzidwa ndi dzuwa.
Vuto lina la mtundu wa pigmentation, pamene melanocyte imachoka mu dongosolo pambuyo kutupa kwa epidermis (chikanga, ziphuphu zakumaso, psoriasis, lichen). Khungu ndiye amachitira ndi kupanga owonjezera melanin. Nthawi zambiri, zotupa zilizonse zapakhungu zimatha kupanga mdima kapena kuwala.
Chigoba cha mimba
Amawopedwa kwambiri ndi amayi apakati, chigoba cha mimba (kapena chloasma) chimakondedwanso ndi dzuwa. Amadziwika ndi mawanga a bulauni kapena ocheperako, osawoneka bwino, pamapepala kapena ma contour osakhazikika omwe nthawi zambiri amakhala pamphumi, masaya, kapena milomo. Matendawa amapezeka nthawi zambiri ali ndi pakati koma amatha kuwonekeranso pamapiritsi kapena modzidzimutsa. Nthawi zonse, Kutentha kwa dzuwa popanda chitetezo kumakhalabe choyambitsa. Azimayi omwe ali ndi khungu lakuda kapena lakuda amakhala ndi mwayi wokhala ndi chigoba cha mimba, koma khungu labwino silimaloledwa. Ndipo amuna ena amakhudzidwanso nthawi zina.
Zaka mawanga
Kuwonekera kwa dzuwa kwa nthawi yayitali kungayambitse mawanga akuda otchedwa lentigines kapena "maluwa akumanda" kupanga. Iwo ndiwo chizindikiro cha ukalamba wa khungu. Dzuwa lambiri limapangitsa kuti melanocyte ifooke, zomwe zimagawa melanin mwachisawawa. Madonthowa amapezeka makamaka m'malo omwe nthawi zambiri amakhala ndi kuwala, monga kumaso, manja, mikono, khosi. Matendawa amapezeka pakhungu labwino, lomwe silimakhudzidwa ndi kuwala kwa UV. Koma mawangawa samangokhudza okalamba okha. Amatha kuwoneka asanakwane kuyambira zaka 30, ngati kutuluka kwa dzuwa kunali mwadzidzidzi (ndi kutentha kwa dzuwa) kapena kukokomeza paubwana. Khungu likaphimbidwa ndi mawangawa, munthuyo amanenedwa kuti ali ndi helioderma. Kuyang'anira khungu kumalimbikitsidwa.
Mawanga a Brown: momwe mungawachitire?
Zizindikiro zakubadwa kapena zobadwa nazo ndizosatheka kuzichotsa. Kwa ena, padzakhala kofunikira kuphatikiza mankhwala angapo malinga ndi vuto. Ndiko kuti: malo akakhala akuya, amasanduka buluu. Kuzichotsa kudzakhala kovuta kwambiri. Dermatologist akhoza, monga sitepe yoyamba, kulembera a kukonzekera depigmenting ndi kugwirizana ndi a zonona zonona. Popanda zotsatira, adzatha kupereka maganizo ake kachikachiyama, chithandizo chaukali kwambiri chotengera nayitrogeni wamadzimadzi, kaya ndi laser magawo kapena peels. Kuphatikiza pa mankhwala osiyanasiyanawa, kugwiritsa ntchito mafuta oteteza ku dzuwa tsiku ndi tsiku ndikofunikira. Kuti mupeze zotsatira zabwino, chitanipo kanthu mwachangu momwe mungathere, pakangotha banga kapena posakhalitsa. Choyenera kwambiri ndikuteteza mawonekedwe ake pogwiritsa ntchito mafuta oteteza ku dzuwa.
