I love this product! Just using it hides all kinds of imperfections!! But it's light and doesn't feel thick. I wear masks for work, and it seems to have helped with the pores under my cheeks, which I've always had trouble with...! It does smudge the bridge of my nose, but that can be fixed with a touch-up. It gives you a soft, airy look and makes you look elegant♪♪ What about the cost-effectiveness? I've only just started using it, but if you use a brush, it may go through quite quickly. But I'll definitely be buying it again.
