The other day a client asked me if LED for acne (the blue light) would be the best choice for rosacea. At first I thought red would be better as red light aids in healing. However the blue light is better for killing bacteria to heal blemishes. In the spa, most of my rosacea clients needed everything to be cool so what we did for them was to give them Cold Fusion Facials. Now I'm going to have to do some research to share my best opinion with you. Any thoughts?
