I use MUFE in 128 (although could get away with 140 and 153 if that helps) and I have strong yellow/olive undertones. The SA recommended this to correct sallow/yellow tones and for an overall brightening effect ont the skin. I liked this immediately from the moment I began using it. I love that it's moisturising, so Ive been able to use it around my undereyes and dry areas with no worries. It feels like a light lotion, a similar consistency to the NARS water based primers although it dries very quickly to a somewhat matte feel on the skin (NARS stays very supple). I did half my face first to see the effect of the primer compared to the other half without - and I have to say, it really does work in correcting yellow tones. My skin looked more even and just neutral, but the effect is very subtle and natural looking, if I didnt tell you, you would never know. However, I think I may try the Mauve one next as it's a darker colour so I think it may have an even more pronounced effect on sallow tones. Did it brighten my skin? Well, my skin did feel more luminous but there was no drastic difference. The overall result with this primer is that it does even out the skin, corrects sallow tones and adds luminosity, but the effect is very subtle.
As a base for my HD foundation, it has worked surprisingly well. Im used to using more silicone-feel primers and was addicted to MAC prep+prime spf50 for a while, so this was a new experience for me. It doesn't feel like you're priming your skin - yet my foundation lasted 12 hours, required minimal touch ups and looked glowy and fresh. So Im happy with this.
The biggest improvement is my oilyness. My skin just feels less oily these days! I used to have to powder my skin every few hours with Revlon CS or EL DoubleWear because I felt like they were so thick and make-uppy that they were melting off my face and never stayed fresh looking. I dont have to do this anymore with my MUFE HD primer and foundation. You'd think the moisturising formula would make oilyness worse, but my skin feels so much more balanced and NORMAL for once.
As a primer in its own right, I'm not sure if it would function as well with a foundation from a different brand. But because MUFE is my HG I really won't be trying it anyway! :-) Using these two products together has made my acne-ridden skin look and feel flawless all day, my skin feels so SMOOTH and poreless, my imperfections are invisible and so many people have been complimenting my skin. I love MUFE <3
