Ubwoko bwuruhu rwa Fitzpatrick

Ibyiciro bya Fitzpatrick ni ugushyira ibara ryuruhu muburyo bwa I-VI ukurikije ibiranga reaction yo gutwikwa cyangwa gutwikwa nyuma yizuba:

Ubwoko I: Umweru; byiza cyane; umusatsi utukura cyangwa umuhondo; amaso y'ubururu; ibice

Ubwoko bwa II: Umweru; ubutabera; umusatsi utukura cyangwa umuhondo, ubururu, hazel, cyangwa amaso yicyatsi

Ubwoko bwa III: Cream yera; byiza n'amaso yose cyangwa ibara ry'umusatsi; rusange

Ubwoko bwa IV: Umuhondo; bisanzwe bya Caucase ya Mediterane, ubwoko bwuruhu rwabahinde / Aziya

Ubwoko V: Ubwoko bwijimye bwijimye, hagati yuburasirazuba bwuruhu

Ubwoko bwa VI: Umukara

Muri rusange abantu bemeza ko abanyaburayi n’abanyamerika bafite melanine nkeya mu gice cyibanze cyuruhu, kandi uruhu ni ubwoko bwa I na II; uruhu rwumuhondo mu majyepfo yuburasirazuba bwa Aziya ni ubwoko bwa III, IV, kandi ibirimo melanin murwego rwibanze rwuruhu biringaniye; Uruhu rwumukara-umukara nyafurika ni ubwoko bwa V, VI, kandi ibirimo melanin murwego rwibanze rwuruhu ni byinshi cyane.

Kuruhu rwa laser hamwe no kuvura fotone, intego ya chromofore ni melanin, kandi imashini nibipimo byo kuvura bigomba guhitamo ukurikije ubwoko bwuruhu.

Ubwoko bwuruhu ni ishingiro ryingenzi rya algorithm yagusesengura uruhu. Mubyigisho, abantu bafite amabara atandukanye yuruhu bakeneye gukoresha algorithm zitandukanye mugihe bamenye ikibazo cya pigmentation, gishobora gukuraho itandukaniro mubisubizo biterwa namabara atandukanye yuruhu bishoboka.

Ariko, ikigezwehoimashini isesengura uruhu rwo mumasoku isoko bifite ibibazo bya tekiniki bimwe na bimwe byo kumenya uruhu rwumukara nijimye rwijimye, kubera ko urumuri rwa UV rukoreshwa mugutahura pigmentation hafi ya yose yakiriwe na eumelanine hejuru yuruhu. Nta gutekereza,gusesengura uruhuntishobora gufata urumuri rwerekanwe, bityo ntirushobora kumenya ibara ryuruhu.
