Ixesha elide, abantu abanesikhumba esimnyama baye bajongana nengxaki xa becingaukususwa kweenwele laser: mhlawumbi sebenzisa iindlela zesintu (iincakuba, iikhrimu zokuthoba, ukuweksa) kodwa kufuneka unyamezele inkxamleko yokutsheva okuphindaphindiweyo, okanye umngcipheko wokutshisa nokuba nebala ngokuzama izixhobo zelaser ezingafanelekanga.
Nangona kunjalo, ngenkqubela phambili eqhubekayo kubuchwepheshe belaser kunye{0}}nophando olunzulu lwezonyango, olu khetho lunzima luye lwasonjululwa kancinane. Namhlanje, ukususwa kweenwele ezisisigxina ngelaser kubantu abanolusu olumnyama akusathintelwa-kodwa isisombululo esikhulileyo esixhaswa yimigaqo yenzululwazi kunye nobungqina bezonyango.
Imingeni engundoqo yokususwa kweenwele zeLaser kwiiToni eziMnyama zolusu
Isiseko sethiyori sokususwa kweenwele ze-laser sithi "i-photothermolysis ekhethiweyo"-amandla e-laser afunxwa yi-melanin kwi-follicle yeenwele, eyiguqulela kumandla obushushu, etshabalalisa iiseli ze-follicle stem zeenwele, kwaye ngaloo ndlela inqanda ukukhula kweenwele. Lo mgaqo usebenza kakuhle kubantu abanolusu olukhanyayo kunye neenwele ezimnyama ngenxa yokuba umehluko phakathi kwe-melanin eluswini kunye ne-follicle yeenwele iphezulu, ivumela i-laser ukuba ijolise ngokuchanekileyo kwithagethi ngaphandle kokulimaza ulusu.
Nangona kunjalo, kubantu abanolusu olumnyama (uhlobo lweFitzpatrick IV-VI), i-epidermis sele iqulethe inani elikhulu le-melanin. Xa i-laser irhabula ulusu, i-epidermal melanin ikhuphisana nefollicle yeenwele ze-melanin ukuze ifumane amandla okukhanya{2}}into eyaziwa ngokuba yi-"melanin competition." Oku kunciphisa kakhulu ifestile yonyango ekhuselekileyo, ukwandisa umngcipheko wokulimala kwe-epidermal thermal kunye nokubapost-ukudumba kwepigmentation. Esi sesona sizathu sibalulekileyo sokuba izixhobo ze-laser zakuqala zibangele ukutshisa, amadyungudyungu, kunye notshintsho olusisigxina lombala kubantu abanolusu olumnyama.
