Is hydrogen peroxide safe for the skin to use for a long period of time? I want to bleach my eyebrows, as I changed my hair color to red from dark brown. My natural eyebrow color is black, and I want to use peroxide daily on the brows until I get a dark blonde. Since I'm planning on keeping the hsur color for a while, I guess I will have to keep the brows discolored and keep using the peroxide. I need to know how often should I use it after getting the desired color and if it is actually safe for the skin to keep treating the arch/brow area with the peroxide.
