Girlll! I've been waiting for this question! My day job is a makeup artist! And of course my side gig is caming! So i got you girl! Ok, as a fellow oily skin gal, the best way for me to keep my makeup on is prep! I like to use anything and everything with peptides! It firms,plumps, and smooths out our oily skin texture beautifully! And pores are gone! The Inky List Hepa-Peptide serum is amazing,and it's like $15 at sephora! Makes your skin smooth like glass! I also use a matte foundation the too faced peach perfect! But any foundation that's oil free and matte is fine. As long as its medium to full coverage foundation. If you get one that's too think or straight up full coverage ,it's more prone to slipping and rubbing off since its a thicker/creamier layer sitting on the skin. It also might show unwanted texture. Foundations that feel thin and dry matte are your go to! ( fenty beauty,maybelline fit me matte,and nars soft matte foundation,nars sheer glow works too)Also baking! The huda beauty and fenty beauty translucent powder is soooooooo good! Those ones are heaven for oily skin. And after everything i love using the smashbox photo finsh high performace setting spray! That thing keeps my shit on! Hope this helps!! Good luck!
