Questions

Quick answers.

Why does mineral makeup make my face itch?
Bismuth oxychloride is a very common cause of itching in mineral makeup. Its crystalline structure physically irritates skin, and it can clog pores. Look for bismuth-free mineral makeup formulations.
Is bismuth oxychloride toxic?
It is not considered systemically toxic, but it is a significant skin irritant. Many people discover they are sensitive to it only after switching to mineral makeup and experiencing unexplained itching and redness.
Is bismuth oxychloride natural?
No, despite appearing in 'mineral' makeup. Bismuth oxychloride is synthetically produced by combining bismuth (a heavy metal byproduct of lead and copper refining) with chloride and oxygen. Its presence in mineral makeup is one reason 'mineral' does not always mean gentle or natural.
Does bismuth oxychloride cause acne?
Yes, for many people. Despite being marketed in mineral makeup that claims to be non-comedogenic, bismuth oxychloride can clog pores and cause breakouts. Its crystalline particles also cause micro-irritation that triggers inflammatory acne in sensitive skin.
What makeup doesn't contain bismuth oxychloride?
Look for mineral makeup brands that explicitly state 'bismuth-free.' Alternatives include mica, iron oxides, and titanium dioxide, which provide similar luminosity without the irritation. Brands like bareMinerals Original does contain bismuth oxychloride, while their Matte formula does not.
Does Numbrrrz use bismuth oxychloride?
No. Numbrrrz lip balms contain no bismuth oxychloride or synthetic pigments. Our formula of Organic Coconut Oil, Organic Jojoba Oil, Organic Beeswax, and Vitamin E focuses on nourishment — no irritating mineral additives.
