What Boron Nitride does

Adds a smooth, silky slip
Reduces stickiness on the skin
Helps lotions spread evenly

Boron nitride is a synthetic compound. It is made by heating boron and nitrogen compounds at high temperature. Its crystal structure looks a lot like graphite, the material in pencil lead. The cosmetic form is a fine white powder that does not dissolve in water or oil. It stays suspended as tiny particles.

Formulators use it because its layered structure lets particles glide over one another. On the skin, that gives a smooth, slippery feel and helps a lotion spread without dragging. The finish feels soft and silky rather than greasy. It is often used in lotions, creams and makeup, and it is generally well tolerated.

Good for

People who like lotions that feel silky and non-greasy, especially those who dislike a tacky finish after applying.

Frequently asked questions

Is boron nitride safe in skincare?

Boron nitride is generally considered well tolerated in cosmetics. Because it does not dissolve, it mostly sits on the surface of the skin. As with any new product, patch testing on a small area first is a sensible habit for sensitive skin.

Is boron nitride the same as boron?

No. Boron is an element, while boron nitride is a compound made of boron and nitrogen. It is a different material with different properties, and its job in cosmetics is about feel rather than any effect of boron itself.
