I think laser hair removal is fundamentally different from what they were selling. I understand they are cutting the hair, not destroying the follicle.

- dogma1138 11y agoWe understand that which means that the laser has to be more focused and deliver higher energy density. Hair removal products are usually in the 20-50W ranges depending on wavelengths, the lightsaber wannabe hand held lasers are usually in the 500-2000 mW ranges and while those can burn skin and pop balloons they aren't powerful enough to burn hair. I just don't see them having the technology to make this work, if they had it would have military applications way before shaving ones. Just for size comparison this is a laser used for soft tissue removal https://upload.wikimedia.org/wikipedia/commons/c/c7/Sharplan_40C.jpg https://upload.wikimedia.org/wikipedia/commons/c/c7/Sharplan... And even it won't burn hair because it works on tissue with high water content only.
