This really is unlike other Benzoyl Peroxide treatments. In the past when I have used Benzoyl Peroxide I have had to be extremely careful with how I applied the product. Even when applying a small amount on a breakout inevitably the surrounding skin would be affected. Previous products caused irritation, redness, and often flaking. This product arrived just in time for the beginning of a breakout. I applied it over night and was pleased that the surrounding skin was not affect. The breakout was soothed and actually shrunk. This product started right in on helping to eliminate the breakout. It never broke skin and even with daily application the outer skin is not irritated by the Benzoyl Peroxide.
