With a “machis” .. well I dont do it myself, cuz I havent mastered the art as my mum says 
… but it doesnt hurt or anything afterwards, but of course it feels VERY warm on the skin and that can be a bit hurting while doing it.. I would say it takes about 10 mins to do my sides and chin .. The hair does come back, but nothing like threading or waxing .. veryyy fine! and this is from someone who had quite dark hair
