You could be experiencing a problem with something not connected with the regimen, or you could be experiencing a reaction to one of the products or an ingredient in one of the products.

You can test products 1 at a time on the inside of your elbow for a couple of days and see how you react there. This can help you figure out if you are reacting to a certain product.

When you say "swollen" that is a concern because swelling and/or severe crusting is a sign of allergy to benzoyl peroxide. So if you really are swelling up, stop using the treatment right away and test it on your inner elbow for a few days before trying it on your face again, and if/when you do go back to your face, try it only on your jawline for a few days. In other words, be careful and methodical.

And of course, if you are experiencing a very bad reaction, see a doctor. No one here at acne.org can give you medical advice.
