About

On an ingredient list it is written as Tin Oxide. It is synthetic (tin(IV) oxide, inorganic).

In the Formula

It is an effect material. It does not add pigment so much as bend light, which is what reads on skin as pearl, glow or a soft-focus sheen. Formally it is classed as abrasive / bulking / opacifying agent (effect pigment).

The Evidence

Its safety for cosmetic use has been assessed by the expert panel review Safety assessment of Tin(IV) oxide as used in cosmetics (Johnson W Jr, 2014, Int J Toxicol, PMID 25568164). We cite what the ingredient is assessed for, not what a finished product was claimed to do.

Honest Limits

Tin Oxide (CI 77861) does its job inside the formula. It is not an active, and nothing on this page should be read as a treatment claim.
