I went to a Mac store to get my makeup done for an outdoor wedding. The makeup artist did use primer. When she put it on my face it felt alright even though I thought it was a bit heavy. I just figured it feels like that because I'm not used to wearing liquid foundation. It lasted all day in the heat and stayed on for pictures outside. The only issue I have with this product is the fact that its so hard to take off. I used every makeup remover I could find and nothing would take it off. I ended up breaking out because of all the scrubbing. There are better foundations out there that are easy to apply and remove. I will probably never buy this foundation again. Mac is very expensive and not really worth the huge price tag.
I bought this product as my previous MAC foundation was too dark for my skin, I love this foundation it lasts all day even if it moves abit it is completely blendable so it looks fresh all day! I love the fact it has spf 15 which protects your skin in all weathers I find this is a really good foundation for all occasions as it is blendable therefore you can have light coverage and build it up to maximum! I apply this with my cosmopolitan foundation brush.
I've tried quite a few foundations and my Mac Studio Fix Fluid is my "go-to" foundation. Even though I have foundations that I use for a good month or so that I really enjoy. I always come back to my Studio Fix Fluid. It gives me the coverage I need and the finish that I love. The price range for this foundation is just in between drugstore and higher end products. So very affordable.
