Ultimate Protection SPF 28 is a physical sunscreen that contains both zinc oxide and titanium dioxide, providing broad spectrum coverage from harmful UVA and UVB rays. Because it is a zinc-based sunscreen, it can leave a white appearance on darker skin tones. This noncomedogenic sunscreen is safe for sensitive skin and skin prone to all types of acne and acne rosacea. Pro Tip: reapply every 2 hours for ultimate sun protection.
