&gt; The guy invented Intense Pulsed Light, i.e. the laser technology used in hair removal<p>As somebody who has actually undergone laser hair removal, I can tell you that IPL is <i>not</i> laser. It&#x27;s an alternative to laser that&#x27;s used by some hair removal places, and it&#x27;s generally considered less effective and less permanent than real laser. IPL is the budget option. It&#x27;s also not technically a laser, either. IPL is non-coherent light over a range of wavelengths, while laser is coherent light over a single wavelength.<p>The most effective options for laser hair removal are alexandrite and maybe diode lasers for people with pale skin and YAG lasers for people with dark skin. You won&#x27;t see IPL recommended over any of these.<p>Mind you, if what this project is selling is a temporary way to get rid of hair, IPL might be ideal for this particular use case.
