Unlike mixing two liquid foundations, you can only use cream or liquid and powder foundations separately.
What you do is:
1) Apply your cream or liquid foundation to skin that is clean, moisturized, and primed. Blend your foundation into your skin nicely, ensuring you don’t move it around.
2) You can now go in with your powder. With a fluffy makeup brush, dab loose powder on your face, especially parts you tend to get oily.
Ensure that you don’t apply too much powder by tapping off any excess so that you don’t end up with a white clown look. Most cream foundations are oil-based and tend to leave you with a shine, and powder foundation will help minimize that and leave your face looking subtle.
This method is excellent if you have sensitive skin because you only use a little foundation on your skin. Meaning you don’t put too many ingredients on your skin, and you get an easy time eliminating your makeup toward the day’s end. You get your perfect finish while still taking care of your skin and protecting it from irritants.
