The product I totally love and want to share with you all today is Lancome's Dual Finish powder.
I just love this powder! It can double as a foundation, too! It's all in the application: use a damp sponge for full-coverage matte finish, or a dry puff over existing foundation for a flawless look.
I use it as a powder over my Teint Idole Ultra foundation, and it does result in a flawless finish--well, at least as flawless as it can be when working with an imperfect canvas!
Give it a try and I just know you'll love it!
