Benzoyl peroxide, depending on the strength, can dry up the skin. I would wait till the IPL treatment redness subsides before using BP.Best, Dr. Karamanoukian Los Angeles

Once your skin is healed--no longer red, pink or swollen-- you may resume the benzoyl peroxide. Plan on waiting about one week until using it, and you will find it actually will help slough off any remaining dryness quicker as it will lightly exfoliate the skin.

Thanks for your question. The big thing in recovery from IPL is that your skin will be quite dry and tend towards flakiness. You'll need to be using a really good moisturizer as well as sun screen. As you know, benzoyl peroxide can dry your skin as well. If I was you, I'd wait a couple of weeks before resuming its use, but your skin will tell you when it's time.
