About this sunscreen

BiON Titanium Dioxide Suncream SPF 35 pairs the mineral filters Zinc Oxide and Titanium Dioxide with the chemical filters Octinoxate and Avobenzone, making it a hybrid formula rather than a pure mineral one. It wears with a dewy finish, a low white cast and a lightweight, non-stinging feel that is generally comfortable for most skin. SPF 35 gives good broad protection for everyday wear. Its 71.7/100 score places it solidly above average, helped by the added mineral filters.

Does the BiON Titanium Dioxide Suncream SPF 35 leave a white cast?

It is rated low for white cast despite containing mineral filters, and it wears with a dewy finish, so it should look natural on most skin tones.
