Ruby Powder

What Ruby Powder is & what it does

Ruby Powder is a finely milled mineral powder derived from ruby, a corundum gemstone composed largely of aluminum oxide. As a cosmetic ingredient it is typically used as a decorative or marketing-driven additive that can contribute light-reflecting or shimmer effects to a formula. Because corundum is very hard and chemically stable, the powder is generally inert on the skin.

What does Ruby Powder do in skincare?

Ruby Powder is a finely milled mineral powder used mainly as a decorative or shimmer additive that can give a formula light-reflecting effects. Because it is made of corundum, a very hard and stable mineral, it is generally inert on the skin. Its role is cosmetic appearance rather than a treatment function.

Is Ruby Powder safe?

Ruby Powder is composed of corundum, a chemically stable and inert mineral, so it is generally considered well tolerated when used as milled powder in cosmetics. As with any particulate, the finished product's formulation matters. If you have specific concerns, consulting a professional is reasonable.

Is Ruby Powder natural or synthetic?

Ruby Powder can be made from natural ruby or from synthetically grown corundum, both of which are essentially aluminum oxide. The two sources share the same core mineral composition. Manufacturers may choose either depending on cost and consistency.
