Body SPF · Sub-chapter 01
Both are FDA-approved. Both help protect against UV rays. The real question is which one you will actually finish the bottle of — and why.

What the two filter types actually mean
Mineral sunscreens use zinc oxide, titanium dioxide, or both. Chemical sunscreens use organic (carbon-based) filters — avobenzone, octisalate, octocrylene, homosalate, and others. The FDA recognises both groups as safe and effective when used as directed. Mineral filters are sometimes called 'physical' because they sit on the surface. Chemical filters absorb UV energy and convert it to heat.
How they compare
- Texture on the body: mineral tends to be thicker and slower to absorb; chemical is typically lighter and faster.
- White cast: mineral, especially zinc-heavy formulas, often leaves a cast. Chemical is generally invisible.
- Water resistance: both are available in 40- and 80-minute water-resistant formulas — check the label.
- Sensitive skin: zinc oxide has a gentle skin record. Patch test chemical filters if you have reactive skin.
- FDA status: zinc oxide and titanium dioxide are GRASE (Generally Recognised As Safe and Effective). Common chemical filters remain under FDA review; none have been declared unsafe.
