I have white hairs on my chin, upper lip and sides of my face. What laser will remove them?

Unfortunately, light hair doesn't respond to laser hair removal treatments in the same way that dark hair does. The efficacy of the treatment can depend on your hair pigmentation. Hair with deeper pigmentation is able to absorb more of the laser energy, meaning the treatment can be less effective on light or white hair. All laser hair removal processes are based around this principle, so at this moment, your best option for hair removal wouldn't involve a laser.

Hi, Thank you for your question. Unfortunately there are no lasers to treat grey hairs. You can try electrolysis. Kindly meet a board certified plastic surgeon or a dermatologist who can treat you. Best of luck. 

Thank you for your question. Please consider consulting in-person with a board certified facial plastic surgeon so you can review the right procedure for you. 
Best wishes,
