Re: Fix Fluid help....PLEASE
Yes, I agree with MAC's Prep+Prime Skin Primer or Smashbox. Personally, I just use Clinique's Pore Minimizer to deal with the oil on my chin & nose. Sometimes MAC's Skin Refined Zone, if my pores on the sides of my nose are looking rather large.
Make sure you wait 5+ minutes after applying lotion and/or sunscreen, to apply the primer and other 5+ minutes before applying foundation.
What are you using to apply the foundation? I use a 109 brush that I mist with a spray of Fix+ and gently dip my brush into the foundation, stipple on, starting on my cheeks, where I need the most coverage, and then buff in. I have an oily t-zone and rosacea on my cheeks, which makes them a bit dry. If you want to see how I do this, there's a video on my YT Channel, link below. It might or might not help.
It's kinda hard to see all my skin flaws (in the video), but this is definitely my favorite foundation.
