Hello, possible reason for a product to stop working is whenyour skin becomes used to it.Making it important to rotate your products every so often. Sometimes changing routines, products and order-of-use can lengthen the amount of time a product gives you positive skin benefits.

Actually it's impossible for your skin to get used to benzoyl peroxide. That can't be the issue.

Usually, it's one of the following:

• A new product - some products, particularly sunscreens can wreak havoc
• A new medication - some medications cause acne
• Consistent irritation like an irritating mask

Also, check this page and go to "biggest mistakes people make on the regimen." And lastly, make sure you're using AHA+ with the regimen.
