I didn't get matched at the MAC counter or anything... I figured that my skin tone was pretty much identical to R's, so I just grabbed the Medium - Turned out to be a perfect match; I can't tell it apart from my skin.
I wore it for a full 10 hour day today, and I'm quite pleased.
Before I begin, I want to inform that I've never worn foundation in any form; at least, not for the function of foundation. When I use foundation (in liquid form only), it serves as a spot concealer.
After washing my face, I applied my usual Bioderma Sébium Pore Refiner (my post on it here) to my T-zone. Then, starting from my T-zone, I buffed the MSF all over my face with my Real Techniques Buffing Brush (my post on it here). I found that it was a light coverage that was build-able to reduce redness and even out my skin. The MSF isn't enough coverage for my under-eye darkness and dark pigmentation spots, so I used my Chanel Perfection Correcteur Concealer; however, I found that I didn't need as much of my concealer as usual. After I applied my concealer, I went over my face with the MSF once more, really lightly, to just set everything.
Normally, I would apply my pore refiner to my T-zone, conceal, and apply my Tarte Smooth Operator Amazonian Clay Translucent Finishing Powder all over.
Even though I didn't apply any moisturizer today, the MSF didn't enhance any dry patches (I have combination skin, but within the last couple of weeks, I've been having more dry-normal skin). Sometimes, if I haven't moisturized, I've found that my Tarte finishing powder will slop up the little oil on my skin and make my top of nose and chin look like a flaky mess.
Also, the MSF was able to even out my complexion and keep it matte without making me look like a powderpuff. Even after a full day out, I felt like it handled the accumulation of oil pretty well. The MSF seemed to just slightly soak up the excess oil, leaving my face looking semi-dewy matte. My complexion actually looked better as the MSF blended with my natural oil (as gross as it sounds haha).
Overall, I'm quite impressed and am pleased to have purchased it. It functions like my Tarte powder, but seems to be better at handling my combination skin's oil and dry patches. Considering I paid $36 CAD for my Tarte powder, $34 CAD for this MSF isn't bad. My Tarte powder still looks full and brand new, so I'm sure the MSF will last forever too. I will be travelling quite a bit for vacation this Autumn, and starting in January, I will be travelling twice a week for work, so the MSF is perfect - It will be a more travel-friendly option.
