I came across this purely by accident! I mix a tiny bit of each of these (dime size or less) in my hand and apply before my makeup. I have found that I don't have to use foundation now, just powder. Advise using extra sunscreen if you are going in the sun as the benzoyl peroxide will make you more sensitive.
Acne moisturizer with salicylic acid (I used Clean & Clear)
5 or 10% Benzoyl Peroxide Cream(Zapzyt or Dr Sheffields from Dollar Store)
Salicylic Acid Acne Cream (found at Dollar Tree labeled as Acne Cream in gray & orange box)
Regular Moisturizer with Vit E and AHA acids or similar or your choice (I used Walmart Equate)
Basically you can even mix your foundation with this and apply. Let dry completely. I wash my face at night, use toner then this. I also use it in the daytime after washing with toner again. But sometimes not, still works! Same ingredients as Pro-Activ and way cheaper, salicylic acid clears dead skin and pores making way for benzoyl to work effectively.
I hope this helps others! Love your page, Suzanne!
