This product is very easy to use and does exactly what it promised to do. However, the application sponge is a bit hard to use and gets dirty very easily hence why I only give it 4 stars. I prefer to apply this product using a powder brush. I put it on after my moisturizer and before my foundation. I found the best foundation to use with this is bare minerals since it blends better with another powder. I finish with maybellbe fit setting powder and I'm good to go all day with my skin looking poreless and matte. For the acne property, I use Mario badescu drying lotion at night but that's difficult to hide with makeup during the day so this special healing powder is my go-to daytime acne treatment. The sulfur ingredient in it works just as well as acne sulfur soap bar but without the smell.
