The formula
A pressed mineral powder foundation that works two ways: swept on dry for a natural matte finish that keeps shine in check, or pressed on damp for fuller, closer-to-skin coverage. Boron nitride and nylon-12 scatter light to soften the look of pores and uneven texture, while an absorbent mineral blend helps hold down surface oil through the day.1 A silicone emollient system keeps the powder smooth and skin-true rather than dry or chalky, and the formula is talc-free.
Birch is a medium shade with warm undertones, made for medium skin.
Finish: natural matte, soft-focus · Coverage: buildable, wet or dry · Talc-free
Paraben-free. Cruelty-free. Made in North America.
1 Describes the powder's optical and oil-absorbing performance, not a clinical measurement.
