I switched from using 10% for years believing this would be gentler on my skin. Boy was I wrong. I am a 50 year old male with cystic acne on my nose and chin. It was well under control using 10%.  Took about a week of using this for it to recur. After a month it was horrible. Took about a week or 2 using the 10% again to get it back under control. 2.5% isn't enough for everyone. 

This didn't work for me at all. I had to revert back to 10% benzoyl peroxide which works very well for me.  I am a 50 year old male with cystic acne on my nose and chin. Within a week of starting this, I started getting cysts and after 4 weeks it was horrible. Thought buying a big tube was a good idea, but now it will just go in the trash.
