This is a used acne face lamp by Dr Kern, this is currently selling on Amazon for £200, the lamp is in very good condition with all lamps working. I have only had this lamp for 6 months and my skin is much clearer, you must be persistent with this acne treatment, it's a slow process but worked for me when I had tried every single spot treatment available and had no luck.
