It is because they don't work.
All the "over the counter" treatments will get rid of acne but will not prevent the acne from coming back.
Since the products don't stop the acne from coming back, you will continue to buy their products.
The sad thing about this is that all the major companies understand this and don't care.
After all, if you stopped buying their products, they would no longer be in business.
The product that these companies make will dry out your skin so the acne will go away.
The problem with that is that the acne will definitely come back.
The secret to truly get rid of acne is simple.
You need to find a company that not only offer you a treatment but will offer you a prevention.

So quit wasting your time with all the same "over the counter" treatments that don't work.
