La Roche-Posay Anthelios Mineral Ultra-Light Face Sunscreen

La Roche-Posay's fully mineral face sunscreen. Titanium dioxide and zinc oxide, no chemical filters, in a fluid that absorbs better than most mineral formulas manage.

At a Glance

Recommended

Mineral filters like titanium dioxide and zinc oxide sit on the skin surface rather than absorbing in, which makes them a good choice for reactive skin, rosacea, and skin recovering from a procedure. When chemical filters sting, this is the fallback that still feels like a modern sunscreen.

The hard part of mineral formulas is that they can feel heavy and leave a film. This one absorbs unusually well and avoids most of that. The brand is honest that it can still leave a cast on some skin tones, which is true, especially on deeper skin.

It is fragrance-free, without oxybenzone, and carries the Skin Cancer Foundation's recommendation. Let your moisturizer absorb first, since it can pill over some of them.

How it works

When chemical filters sting, this is the fallback that still feels like a modern sunscreen.

100% mineral, fragrance-free, no oxybenzone. Mineral filters sit on the skin surface rather than absorbing in, so they are the safer bet for reactive skin, rosacea, and anyone recovering from a procedure.

It absorbs unusually well for a mineral formula. This is the hard part of mineral sunscreen, and this one does better than most — it does not leave the heavy, sitting-on-top film that gives mineral sunscreens their reputation.

Water-resistant for 40 minutes, and carries the Skin Cancer Foundation's recommendation.

Everyday habits

How to use it

When: Every morning, as the last step in your skincare.How much: About 1/4 teaspoon for the face. Most people use too little. Where: Face, ears, neck, and hairline. Reapply: Every 2 hours outdoors, and after sweating or swimming. It is water-resistant for 40 minutes, so it is not a swimming sunscreen. White cast: This is an untinted mineral formula and can leave an ashy or white cast on deeper skin tones.

Who should be careful+

It still leaves a cast. La Roche-Posay's own dermatologist consultant says so on the product page — mineral filters "can leave an ashy, purple or white cast on some skin tones." Honest of them, and true. On deeper skin tones, expect it.

It pills over some moisturizers. Let your moisturizer absorb fully first.

It is $40-plus for 1.7 oz — expensive for a mineral sunscreen, and Vanicream's does much the same job for a third of the price if you can live with a heavier feel.

40 minutes of water resistance, so not a swimming sunscreen.
