I used this for the first time at my friends skin salon. My face was extremely red as I had a rosacea flare up, after sitting under this for 30 mins I saw a dramatic difference to the redness. I decided to purchase one for myself and have noticed a great improvement in the oiliness and redness of my skin. The blue light is great for managing my acne and the red light also helps the redness of my rosacea. Overall this is a great little machine. The eye goggles are comfortable too.
