It&#x27;s sad that people thought it was real, forget about lasers and stuff it&#x27;s basic common sense.<p>A AAA battery doesn&#x27;t store enough power to drive a laser capable of burning hair for any reasonable amount of time.<p>When the laser isn&#x27;t interrupted by the hair it has to go some where which means that heat is produced, if it can get something hot enough to burn the hair off it would get hot enough that you won&#x27;t be able to hold it yet alone put it to your face.<p>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>And most importantly burnt hair smells like shit....<p>P.S.
I assume that most people know at least 1 person that did laser hair removal, they should know it&#x27;s a very painful and long process and it works only on dark hairs so again using this to shave anything but a fairly dark beard would never work.
