Absolutely love this prep and prime transparent finishing power. I have been using it for 4 years now and the Things I loveeeee about it - Can be worn under foundation to prep and prime... Obviouslyyyy. However I use it as a finishing power also and lightly brush it on top of my foundation to give me that flawless porcelain doll finish. My skin used to be comparable to the oil slick before I used this. However my skin now stays matte and perfect all day -Everydayyy. Even my enlarged pores seem none existent with this product. I have tried MUFE's HD micro finish powder which I absolutely hated due to the harshness and chalkiness in the look and smell. Whilst the Mac's prep and prime transparent finishing powder is truly transparent, has no fragrance or harsh chalky look to it when applied to the skin. I also use it under my eyes before/after concealer and foundation to prevent those dreaded creased Cakey foundation lines under my eyes. I feel this product also ensures your skjn is looking flawless and picture ready. The only negative about this product I wish I could change is the size. It is quite a large size and can be quite difficult to carry about with you when your on the go. If Mac could make a travel size version of this I would give this product 10/10.
