What the % on the label really means

Position on the label is your guide. Near the top means a quick-dry texture; if your skin is currently reactive, choose an alcohol-light sunscreen instead.

⚠️ Ceiling: High in the ingredient list means a fast, weightless finish and a higher chance of stinging on compromised skin. There is no agreed safe or unsafe threshold.
