Niba uzi nezaIgipimo cya UVikoreshwa mu iteganyagihe, uzi ko ipima imbaraga z'imirasire y'izuba ya ultraviolet — igufasha gupima vuba uko ushobora gushya cyangwa gushya.
Ariko iyo bigeze kuriibitanda byo gusiga ibara ry'uruhu, igipimo cya UV gikora mu buryo butandukanye gato.
Reka turebe icyo ikigereranyo cya UV mu duti two gukaraba uruhu bisobanura, uburyo gikabije ugereranije n'izuba risanzwe, n'icyo bivuze ku ruhu rwawe.
1. Gusobanukirwa igipimo cya UV
ItsindaIgipimo cya UV (UVI)ni igipimo gipima imbaraga z'imirasire ya ultraviolet igera ku ruhu rwawe.
-
A UVI ya 1–2bivuze ko umuntu ashobora guhura n'ikibazo gito (ingaruka nke)
-
3–5iri hagati
-
6–7ni hejuru
-
8–10ni hejuru cyane
-
11+birakabije
Imirasire y'izuba yo hanze ikunze kuba hagati yaKuva kuri 0 kugeza kuri 12, bitewe n'igihe cy'umunsi n'aho uherereye.
2. Igipimo cya UV mu buriri bwo gukaraba
Ibitanda byo gusiga ibara ry'uruhu niikomeye cyanekurusha urumuri rw'izuba rusanzwe — niyo mpamvu amasomo agirwa magufi.
Uburiri bwinshi bugezweho bwo gukaraba butanga urugero rw'imirasire y'izuba rungana naIgipimo cya UV kiri hagati ya 10 na 15, kandi muri bimwe mu bikoresho bifite umuvuduko mwinshi, bishobora no kugera kurikugeza kuri 20 cyangwa hejuru.
Ibyo bivuze koIminota 10 mu gitanda cyo gusiga ibara ry'uruhubishobora gushyira uruhu rwawe ku mirasire ya UV nk'ukoisaha imwe cyangwa irenga ku zuba ryo mu mpeshyi rya saa sita.
3. Impamvu imbaraga za UV ziri hejuru cyane
Imikoreshereze y'uburiri bwo gusiga ibara ry'uruhuamatara ya UV agenzurwabitanga uruvange rwihariye rwa:
-
Imirasire ya UVA (90–95%)– ishinzwe gukurura ibara ry’uruhu ako kanya no guhindura uruhu rwinshi
-
Imirasire ya UVB (5–10%)- gushishikariza ikorwa rya melanin no kugira ibara rirambye
Iyi ngano yagenewe gufasha abakoresha kugira uruhu rw'umukara vuba, ariko nanone yongera amahirwe yoKubura uruhu, kurakara, cyangwa gusaza imburagiheiyo bikoreshejwe kenshi cyane.
4. Igihe cyo Gushyira Ibara ry'Umutuku mu Mutekano Hashingiwe ku Gipimo cya UV
Kubera ko ubukana bwa UV buri hejuru, igihe cyo kwigaragaza kigomba kuba gito.
| Igipimo cya UV mu Gitanda | Urwego rw'ibyago | Ishusho Isabwa (Abatangira) |
|---|---|---|
| 10–12 | Hejuru cyane | Iminota 5–7 |
| 13–15 | Bikabije | Iminota 3–5 |
| 16–20+ | Cyane cyane | Iminota 2–4 (ntarengwa) |
Buri gihe kurikiza amabwiriza y'umwuga ya salon yawe cyangwainama z'uwakozeku gishushanyo cyawe cyihariye cyo gusiga ibara ry'uruhu.
5. Kurinda uruhu rwawe mu gihe cy'imirasire y'izuba nyinshi
Kugira ngo ugire ibara ry’uruhu mu buryo butekanye kandi bunoze, ibuka inama z’ingenzi zikurikira:
Ambara buri giheUburinzi bw'amaso bwemewe na FDA(amataratara yo kwisiga ku zuba)
Koreshaamavuta yo kwisiga cyangwa accelerator asabwa na salonkugabanya ubwumye
Komeza amasomointera iri hagati y'amasaha 24-48 n'indi
Shyiraho umukonoamavuta yo kwisiga or amavuta yo kwisiga nyuma yo kuvanga ibara ry'uruhunyuma y'isomo kugira ngo amazi akomeze kwiyongera
Irinde kwisiga ibara ry'uruhu niba uruhu rwawe rufitegutwikwa n'izuba cyangwa gushwanyagurika
6. Itara ritukura ugereranije n'itara rya UV
Niba ushaka inyungu zakuvugurura uruhuhatabayeho kwibasirwa n'imiraba ya UV, tekereza kuibitanda byo gusiga ibara ry'umutuku.
Bakoreshauburebure bw'umurambararo butari UV (630–660 nm)bifasha kunozaikorwa rya kolajeni, imiterere y'uruhu, no gukomera, itangaurumuri rutekanye kandi rushingiye ku mucyonta ngaruka zo gushya kw'ibara ry'uruhu.
Zimwe mu buryo bugezweho bwo guhuza ibintu, nkaItara ritukura rya MERICAN + ibitanda byo gusiga ibara ry'imirasire y'urumuri rwa UV, bigufasha guhindura igihe cyawe kugira ngo gibe kiringaniyeubwiza n'umutekano— guhuza iterambere ry’amabara karemano n’ubwitonzi bworoheje bw’uruhu.
Ibitekerezo bya nyuma
ItsindaIgipimo cya UV mu biti bisukura ibara ry'umurabaubusanzwe nihejuru cyane kurusha izuba, niyo mpamvu ibiganiro biba bigufi kandi bigenwa neza.
Ukurikije ubukana bw'imirasire ya UV, ukurikiza imipaka yo kwisiga, kandi ugakoresha uburyo bwo kwita ku ruhu, ushobora kugera ku ibara ryiza kandi ringana mu mutekano.
Kugira ngo ubone uburambe bugezweho kandi bunogeye uruhu, hitamoIkoranabuhanga rya MERICAN ryo gusiga ibara ry'urumuri rutukura— byagenewe kongera ubwiza bwawe mu gihe birinda ubuzima bw'uruhu rwawe.
