Why does sunscreen sting my eyes when I sweat?

How can I reduce the stinging?

1. 1Choose a broad spectrum sunscreen with SPF 30 or higher and water resistance. Broad spectrum means protection against both UVA and UVB rays.
2. 2Apply sunscreen generously to dry skin before heading outside. Cover exposed skin, including your ears and neck, rather than using a thinner coating to avoid discomfort.
3. 3Consider a sunscreen stick for the skin around your eyes. Keep sunscreen out of the eyes themselves, and do not spray sunscreen around or near your face.
4. 4Wear sunglasses with UV protection and a hat alongside sunscreen. Sunscreen alone cannot provide complete sun protection.

For sensitive skin, mineral sunscreens containing zinc oxide or titanium dioxide are an option. Choosing mineral filters is advice for sensitive skin, not a way to predict eye comfort. Before using a new sunscreen, test a small amount on your inner forearm and check for a reaction after 48 hours. A skin test checks skin tolerance, not whether the product will sting your eyes.23

What should I do if sunscreen gets into my eyes?

Rinse your eyes with water to remove the sunscreen, and avoid rubbing them. Burning from an external irritant generally settles once the irritant is removed. Stop using the sunscreen and ask a doctor if a rash develops. Burning that also happens away from exercise can have other causes, including dry eyes or allergies. If burning has continued for a few weeks and compresses or eye drops have not helped, see an eye doctor.14

Should I apply sunscreen before an early morning run?

Yes, apply sunscreen to uncovered skin before an outdoor run in daylight, even if the run is short. An early start is not the same as no UV exposure. UVB intensity changes with the season, location and time of day; daily sunscreen is particularly relevant when the UV index is forecast to reach 3 or higher. Cloud cover is not a reason to skip protection.356

How long should sunscreen settle before I start sweating?

Apply sunscreen to dry skin at least 15 minutes before going outdoors, following the bottle's directions. For outdoor workouts, allowing 30 minutes before heading out gives sunscreen time to settle before your first sweat can wash it away. Applying sunscreen as you start running skips that settling time; putting it on before getting ready is the more practical sequence.25

How do I reapply sunscreen during a long run?

Carry sunscreen and plan a stop to reapply it generously to exposed skin approximately every two hours. Heavy sweating calls for earlier reapplication, following the water resistance interval and directions on your bottle. A higher SPF does not extend the reapplication interval. A facial moisturizer with SPF still needs outdoor reapplication, even if its job title sounds more domestic.237

Does wiping sweat off my face remove sunscreen?

Towelling off can remove sunscreen, so wiping your face is a reason to reapply sooner rather than assume the original coating is intact. Sweat itself also affects protection. If you repeatedly wipe sweat away during a run, account for that in your reapplication plan instead of relying only on the two hour clock.3

What does water resistant sunscreen mean for exercise?

Water resistant sunscreen is formulated to stay on better during swimming or sweating. On US labels, the claim states whether protection remains effective for 40 or 80 minutes during those activities. Water resistant is a limited label claim, not a promotion to permanent face furniture. No sunscreen is waterproof or sweatproof. Choose it for exercise, but still reapply after heavy sweating and follow the label's instructions.237
