&gt; There&#x27;s no way you would ever could get the laser beam close enough to the skin for a smooth shave without burning your skin off<p>That doesn&#x27;t make sense. Of course you can remove hair with light. IPL isn&#x27;t anything new, and this product is apparently from someone who has worked in that field for a long time.<p>&gt; it&#x27;s a very painful and long process and it works only on dark hair<p>.. 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&#x27;s certainly not against &quot;common sense&quot;. And there are prior patents in delivering IPL by fiber.<p>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&#x27;re not impractically big, much like a hair dryer.
