I have a super good skin care routine. And I spend a lot of money on my skin care products. But still can't seem to get flawless foundation. I've tried several high end foundations. I've tried beauty blenders and high end foundation brushes. And it seems like no matter what my foundation is either patchy, streaky, or just not blended all the way. Any tips? What's your ladies foundation routines, what products/applicators do u use?
