Physical sunscreen vs chemical sunscreen: Physical wins for acne-prone skin

Physical blockers (zinc oxide, titanium dioxide) are less likely to clog pores and irritate breakouts than chemical sunscreens. Zinc oxide is anti-inflammatory, helping calm redness, while chemical formulas can sting or trigger reactions, especially with retinoids or acids. The downside: some physical sunscreens feel thick or leave a white cast, but micronized or tinted versions fix that.
