## Definition of Mineral sunscreen
Mineral sunscreen commonly refers to a sunscreen formulated with zinc oxide, titanium dioxide or both as UV-filter ingredients.

## What the name identifies
“Mineral sunscreen” is a common descriptive name for sunscreen products using zinc oxide or titanium dioxide as UV-filter active ingredients. Both are used as sunscreen active ingredients. The phrase itself is not a numerical SPF rating, a tested US broad-spectrum claim, or a formal certification that every product bearing it performs alike. Two formulas naming the same filter can have different finished-product labels and instructions; the ingredient name is not a substitute for those product-specific results. To understand a particular product, identify its active ingredients and then read its separately stated SPF and UVA-related claims rather than inferring them from the word “mineral.”

## How to read a US label
Broad-spectrum sunscreens help protect against both UVA and UVB, whereas SPF values primarily indicate UVB protection. Not all sunscreens are broad spectrum, so look for that description on the label. The broad-spectrum designation in the current deemed final order is an optional labeling claim with a required test if used; a mineral description alone does not say whether the finished product passed that test. See [broad-spectrum sunscreen](/glossary/broad-spectrum-sunscreen/) for this distinction. Use broad-spectrum SPF 15 or higher as directed, alongside protective clothing and limited sun exposure. It advises reapplication at least every two hours, more often when swimming or sweating. A filter name cannot replace these use directions.

## Separate actual rules from proposals
In the US, sunscreens are regulated as OTC drugs. A proposed US sunscreen rule addressed zinc oxide and titanium dioxide, but a proposal is not itself a final approval of every mineral formula. A proposal is not itself the current final rule. Distinguish existing US sunscreen rules from proposed amendments; neither implies blanket approval of all mineral formulas. In the US, moisturizers and makeup sold with sun-protection claims can be both cosmetics and drugs. The intended use and claims of the finished product therefore matter more for classification than the marketing shorthand “mineral.”

## Across markets and products
Under European guidance, sunscreens are cosmetics and should protect against both UVA and UVB. The recommendation includes UVA efficacy criteria, but does not turn the US broad-spectrum claim into an interchangeable EU label. It says no product filters all UV radiation and recommends precautions in addition to sunscreen. Neither this recommendation nor ingredient listings establishes that mineral sunscreen is universally better tolerated, more effective, or free of visible residue: these statements do not compare every formulation or every wearer. For one named filter, see [zinc oxide sunscreen](/glossary/zinc-oxide-sunscreen/). A useful consumer question is not simply whether a sunscreen is “mineral,” but what its finished-product protection claims are and whether it will be used according to its directions. No specific commercial product or comparative tolerance trial is evaluated by this glossary.
