The light

This is the light (flash) that you apply on your skin. It is not painful et safe! Just put your protective glasses to protect your eyes. I heard so many stories of people being burnt with an IPL machine.. If you look at this one, you notice it is clearly orange. Any IPL machine with a yellowish light are dodgy. Do not use them! You will get a burn! Most of those 'made in China' devices have yellow light. The e-one is made in France and is quality despite a higher price than the Made in China crap. But you gotta pay for quality and above all for your safety!
