How long after applying sunscreen can skin be exposed to water?

As a general recommendation, you should wait at least 20 minutes after applying sunscreen before exposing your skin to water.

This is because sunscreen needs time to penetrate the skin and form a protective layer. If you expose your skin to water immediately after applying sunscreen, the water can wash away the sunscreen and leave your skin not fully protected from the harmful effects of UV rays.

After applying sunscreen, you should wait about 15 - 30 minutes before washing your face.

However, the waiting time may vary depending on the type of sunscreen you use. With chemical sunscreens, it takes longer to absorb into the skin, so you should wait at least 20 minutes after application. Physical sunscreens, on the other hand, usually work faster, so you can wait 15 minutes after application.

In addition, you also need to pay attention to some other factors such as: If you participate in high-intensity physical activities or sweat a lot, you should reapply sunscreen more often, about every 2 hours or after each swimming or bathing.

If you have dry skin, you can wait a little longer before exposing your skin to water. Conversely, if you have oily skin, you should wait a little longer.

To ensure the best protection for your skin, you should read the sunscreen instructions carefully before use and follow the manufacturer's recommendations.

If you wash your face too soon after applying sunscreen, it can reduce the effectiveness of the product.

Some tips to help sunscreen work effectively

Apply sunscreen regularly and generously. Apply sunscreen to all areas of skin exposed to the sun, including the face, neck, ears, arms and legs.

Apply sunscreen at least 20 minutes before going outside. This will give the sunscreen time to absorb into the skin and form a protective layer. Reapply sunscreen regularly, every 2 hours, or after swimming or bathing.

Choose a sunscreen with an SPF of 30 or higher to protect your skin from harmful UV rays. Use a sunscreen that protects against both UVA and UVB rays.
