Purchased this recently and needed something for my oily skin- but, this makes a beautiful glow on the skin. Not for me - it gives a gorgeous glowing sheer and natural finish. Sad I cannot use. 80% left inside. Priced to fly! The container is an air tight pump- so no concern about contamination- ready to use. However I will include the brush it comes with. I only used it once and that can be sanitized (again) if needed.
