I used to struggle with this too, but I got it figured out and now my base lasts sm longer. After skincare or moisturizer, I wait around 10 mins, then mist my face with a hydrating spray, wait another min or so before putting on base. I also like mixing a lil moisturizer + foundation together, and I use as little foundation as possible so it doesn’t feel heavy. Sometimes I’ll just use concealer tbh. Then when I’m blending w a sponge, I mist the sponge w setting n hydrating spray every time I dab it on my face and it makes the base sm smoother and more skin-like. Also make sure ur exfoliating like once a week so there’s no buildup of dead skin. It makes such a difference, mark this as solution
