Is this a mineral sunscreen, and which UV filter does it use?

Yes. Zinc oxide is the sole declared sunscreen active at 19.32%.

What does the sunscreen feel like on the skin?

It has a soft, creamy, lightweight texture that spreads evenly without a stiff or heavy mineral-sunscreen feel. The finish is smooth and softly matte.

Does the green tint leave a white cast, and what does it do for visible redness?

The pale green tone helps visually soften the look of redness and applies without a white cast.

Can it be worn under makeup?

Yes. The finish is smooth and softly matte under makeup. Immediately after application, makeup remained in place without clumping or lifting.

Has it been tested for acne-prone skin?

It underwent a four-week non-comedogenic suitability test involving acne-prone participants. Individual experiences can vary.

What testing supports its use on sensitive skin?

The finished formula underwent a primary irritation test on sensitive skin and an in-vitro eye-irritation test. These assessments do not guarantee that every person will avoid irritation or eye discomfort.

Where does this go in my routine, how much should I use, and when should I reapply?

Apply one to two pumps as the final step of skincare, spreading it liberally and evenly 15 minutes before sun exposure. Reapply at least every two hours.

Should I rely on this sunscreen while swimming or sweating?

This sunscreen is not represented as water resistant, so choose a water-resistant sunscreen when swimming or sweating.

What should I do if no product comes out on the first pump?

Stand the tube upright so the contents move toward the pump, then shake it lightly before pumping. Because the airless tube has no internal nozzle, product may not emerge on the first pump.
