That doesn't make sense. Of course you can remove hair with light. IPL isn't anything new, and this product is apparently from someone who has worked in that field for a long time.

> it's a very painful and long process and it works only on dark hair

.. which is exactly the innovation claimed in the video: this is an IPL-like method that works on light hair by bending them against a fiber. Does it work? I have no idea. But it's certainly not against "common sense". And there are prior patents in delivering IPL by fiber.

The final product could not have such a small battery shown in the video however. The production unit would probably be closer to existing IPL products in size. They're not impractically big, much like a hair dryer.
