In my experience, applying bp over your moisturizer is the least irritating way to do it. I would try that first, just to get your skin used to it. If you’re not seeing a lot of results though, the next in line would be applying it for 5-10 minutes and then rinsing off. If that still doesn’t work as well, haha, then cleanse, wait 15-30 minutes to apply bp, and then wait 10 minutes and apply moisturizer. Also, if you notice any stinging when applying moisturizer, from what I have read benzoyl peroxide and glycerin don’t get along great and it can cause a little bit of stinging until everything is dry and then it goes away. There aren’t many glycerin-free moisturizers available, but acne.org has one without it.
