if you have patches of coarse hair now that you are older [SEP] my grandmother had issues with patches of dark coarse hair on her face chin area as she got older and apparently i have genetically inherited that problem therein lies the problem with using this appliance i must shave before using this thing and then i get to be pinched over and over on that sensitive skin where i just shavedi mean if you find something hurting you do you go back to it willingly noat least when i let the stubble get long enough and then wax the pain from yanking that wax off is much faster and less painful that this light pulsing machine so that said it is just not the way to get rid of hair for me if i had just a few hairs in one spot maybe but not the way the hair grows on my face chin area
