How can you stay sun-safe by the pool?
Whether you’re planning to swim or relax by the pool with a book, following proper sunscreen application is essential for shielding your skin from harmful UV rays.
Before you learn how long to wait to swim after putting on sunscreen, learn how can you stay sun-safe by the pool.
According to the American Academy of Dermatology, opt for sunscreen with at least SPF 30 and use about one ounce (roughly a shot glass) to cover your whole body.
Don’t forget often-overlooked areas like your lips and the backs of your hands. Make sure to protect every exposed part of your skin to stay safe under the sun.
What is sunscreen waterproof?
There are two types of sunscreen. Physical sunscreen contains minerals that rest on the skin’s surface, reflecting UV rays away from the body.
Chemical sunscreen, on the other hand, absorbs into the skin’s top layer. It captures UV rays, preventing them from penetrating deeper and damaging skin cells. Most water-resistant sunscreens fall under this category, though they may include minerals that sit on the skin.
The active ingredients in sunscreen are responsible for protecting against UV rays. These include chemicals like oxybenzone and octinoxate, which are not waterproof and can wash off during swimming, potentially harming marine ecosystems.
To make sunscreen water-resistant, manufacturers add additional components that help it adhere to the skin and resist dissolving in water. One such ingredient is cetyl octanoate, which creates a water-repelling film on the skin and is also found in products like shampoos.
Instead of labeling sunscreens as “waterproof,” many brands now use the term “water-resistant” to avoid misleading consumers about complete protection.
How long does sunscreen last in the water?
Sunscreen generally lasts in the water for up to 40 or 80 minutes, depending on its formulation and labeling. The FDA prohibits sunscreen products from being labeled as “waterproof,” instead requiring them to be labeled as “water-resistant” with specific time limits for effectiveness. Most sunscreens can maintain their SPF protection for 40 minutes or 80 minutes after exposure to water, and this duration must be indicated on the product label.
When using water-resistant sunscreen, it is crucial to apply it 20 minutes before swimming to allow it to properly absorb into the skin; otherwise, it may wash off before it has a chance to take effect 1. The effectiveness of sunscreen can also be affected by factors such as sweating, hot water, and how thoroughly it is applied. For optimal protection, reapplication is necessary after swimming or every two hours, and more frequently if you are in the water for extended periods.
Additionally, some sunscreens may contain specific ingredients that enhance their water resistance, such as cetyl octanoate, which helps form a barrier on the skin. However, it’s important to note that no sunscreen can provide complete protection once submerged for an extended period, so reapplication is essential to maintain effective sun protection.

How long to wait to swim after putting on sunscreen?
Before heading to the pool, apply sunscreen at least 15 minutes before sun exposure to let it fully absorb. At the pool, follow the same rule before swimming. Reapply after swimming and drying off, or every two hours if you stay out of the water.
Keep in mind that water reflection increases UV exposure, with up to 10% of UV rays bouncing off the surface, intensifying their effect. Regular reapplication is crucial to protect your skin from water.
How often should you be reapplying Sunscreen?
Even if you’re staying out of the water, reapply sunscreen every two hours. Physical sunscreens without waxes can wear off as they don’t bond with the skin, while chemical sunscreens lose effectiveness after two hours of UV exposure.
In water, reapply sunscreen more frequently, about every hour. Always dry your skin before reapplying and wait 20 minutes for it to absorb before swimming again. Physical sunscreens don’t require waiting since they sit on the skin, but allowing time for oils and waxes to settle improves protection.
UV rays are strongest between 10 a.m. and 2 p.m., especially in summer. During these hours, consider reapplying sunscreen hourly. Overcast skies block some UV rays but not all, so sunscreen is still necessary.
If you experience sunburn, reapply sunscreen immediately, move to the shade, and cover the affected area with clothing.
Conclusion
In conclusion, knowing how long to wait to swim after putting on sunscreen can make all the difference in protecting your skin while enjoying the water. By waiting the recommended 15-30 minutes, you’re giving your sunscreen the time it needs to properly absorb and form a protective barrier against harmful UV rays. So, the next time you’re gearing up for a swim, remember: a little patience goes a long way for your skin’s health.
And, this isn’t a guide to using sunscreen for swimming, it also covers how you should use sunscreen for climbing and hiking.
