Ukholelwa ukuthi abangane abaningi bonke bathenge ummese wekhishi noma babone ummese wekhishi, kodwa ukukhiqizwa kwensimbi yommese wekhishi kuzodideka, le nto ilungile?
Kuyini lokhu?
Ingabe insimbi engagqwali?
Noma insimbi?
Ungakhathazeki, i-make up yakho encane izokwethula insimbi ye-chrome (
cr）
, umehluko phakathi kwalokhu okulandelayo kwezimpahla ezomile kakhulu.
