About this sunscreen
ISDIN Fusion Mineral Body Ultralight SPF 40 is a pure mineral sunscreen using Zinc Oxide as its only UV filter. It has a balanced, lightweight feel with a low white cast that is unusual for a mineral formula, and it is generally non-stinging with low pore-clogging risk. It layers okay under makeup. The 73.5/100 score reflects solid wear, while the protection is rated moderate, so it is a reasonable body option rather than a top performer.
