Quartz Powder is the finely ground form of crystalline silica used in cosmetics. It's chosen for soft-focus blurring, oil and moisture absorption, and slip, which together refine the look of pores and extend the wear of foundations and pressed powders.
Ground quartz absorbs oil and blurs pores for longer-lasting makeup.

Our take
Is Quartz Powder a Good Ingredient?
Good, because it reliably absorbs oil and blurs texture with a stable, inert profile and generally low irritation. It may be drying for some skin types, and like any fine powder it should be kept out of the lungs, which is enough to hold it under Great.
What it does

Helps reduce surface shine and keep makeup looking neat throughout the day while improving glide during application, and provides a pore-blurring veil for a more even-looking complexion.

Uses in Skincare & Cosmetics
Used in mattifying primers, oil-control setting powders, and pressed compacts to deliver a smoother application and a velvety finish.
Before you use it
Safety
Typically well tolerated on skin; limit breathing in loose powder when applying. Those prone to dryness may prefer formulas balanced with emollients.
