Even though I had to combat dry skin all winter with oils like this one, as soon as Spring hit my foundation started to slide off and wasn’t lasting through the day. I thought I needed to switch foundations and was ready to try Make Up For Ever’s Mat Velvet + when I walked into Sephora. Then, the girl helping me showed me Murad’s Mattifying Primer.I pat it on with a foundation brush (like this) after my serum and moisturizer and before my foundation. It’s been a game changer. I didn’t have to switch up my foundation and it’s been lasting all day. I find that it also helps keep it from transferring. Because of the shininess, I had been blotting my face with a tissue mid-day. I did it out of habit my first day using the Murad primer and was surprised to see none of my foundation came off on the tissue. I like that it has SPF too. I love that I can just add this into my routine in the warmer months and keep the same foundation year-round.
