This is CHANEL Natural Finish Pressed Powder in Naturel - Translucent 2 (30)
I use this to set my foundation so I don’t look oily. I use a large powder brush to apply it. Just the right amount evenly all over my face and neck, and making sure I do not put too much on the eye area. The more powder on the eye area (and even around the mouth), the more creases/lines are built and become visible. This improper blending is called DEMARCATION.
