For me it’s the Tarte Timeless Smoothing Primer and the Maybelline FitMe loose powder.
Tarte leaves me poreless and goes so well with my oily skin. It’s thick so it fills in my pores and it’s not silicone-y so it’s not greasy and provides some oil control.
Maybelline Fit Me loose powder makes my makeup super smooth and does such a good job with preventing creasing.
I think they get overshadowed because they’re so many other products in the same category that receive so much praise and have gone extremely viral.
It’s fairly new product I think because I don’t see many reviews on it online. The Hourglass Airbrush Primer has been my recent hg find. It makes the skin look smooth and filtered without feeling heavy. It’s much better than the Mineral Veil imho.
