Do I apply my acne treatment before or after I moisturize?

My acne treatment is Patricia Wexler MD Dermatology Acne spot treatment, it has 10% benozyl peroxide and I think it%26#039;s sulfur based. When putting lotion after I apply it, it%26#039;s hard to put it on since it has these tiny beads.|||I usually moisturize my skin after I put on the stuff .|||Definately after. If the lotion isn%26#039;t working it would be best to try a new brand. Be careful not to lotion too close to your eyes as it will blend the benzoyl peroxide there too.|||after|||before|||definately after.i use to suffer from it.all gone!!!yay...good luck
