Based on its formula, is this spray suitable for sensitive, acne-prone, or dry skin?

The mineral filters are non-comedogenic and the oil blend is soothing for dry skin, making it generally well-tolerated; however, the presence of alumina and certain emulsifiers may cause irritation for very sensitive individuals, so a patch test is recommended.

What is the specific role and benefit of zinc oxide in this sunscreen spray?

Zinc oxide acts as a broad-spectrum physical UV filter that reflects and scatters both UVA and UVB rays, offering stable, reef-friendly protection without degrading under sunlight, and also provides a mild soothing effect on the skin.

How often should this mineral sunscreen spray be applied, and does it contain any controversial ingredients?

Apply a generous amount 15 minutes before sun exposure and reapply every two hours, or after swimming, sweating, or towel-drying; the product contains E171 (titanium dioxide) and E570 (carnauba wax), which are approved for cosmetic use but are sometimes viewed as controversial, while the mineral filters are widely regarded as safe.
