MAC : Studio Sculpt Concealer

I have a light olive skin tone (pale-ish but more of a yellow undertone rather than pink) which is great because I had a hard time finding a foundation/concealer that matched my skin tone and that did not oxidize. It covers better than anything I've used in the past and I've suffered 7 grueling years of acne, so there was much time spent on experimenting and trying out various products. Of course, nothing can cover a big fatty that projects an inch off your face, yet I find that no matter how big, this concealer never made it worse or by somehow drawing more attention to it. It doesn't help with decreasing oil build up when used alone; however, it won't melt away and create a mess like most. I find it best when I use a regular oil-free moisturizer (e.g. clean and clear day oil-free moisturizer) rather than one that is specifically for blemish-prone skin (e.g. La Roche Posay Effaclar, Avene Diacneal, etc.) when it comes to reducing oil and new formed acne. Save the acne fighting lotion for the night or anytime you're not using the concealer. In terms of reducing acne, I have NO idea to be perfectly honest. Prior to using this product, I used to get moderate to moderately sever acne (I was using a different concealer and foundation at the time) and since then it reduced a lot to more light acne. It just worked for me, so I can't put my word on it and say it'll work for you -- but the coverage is fantastic! To those who actually kept up, reading this review (in which case I don't blame those who didn't because I wouldn't have -- haha) then the bottom line is: IF YOU'VE TRIED EVERYTHING THEN IT'S WORTH A SHOT!
