What is the best way to apply sunscreen?

When it comes to protecting your skin from the harmful effects of the sun, applying sunscreen correctly is crucial. But what is the best way to apply sunscreen to ensure maximum protection? Let's dive into the science behind sunscreen application.

How much sunscreen should you use?

The general rule of thumb is to apply about 1 ounce (30 milliliters) of sunscreen to cover your entire body. This is roughly equivalent to a shot glass full of sunscreen. Using less than the recommended amount can significantly reduce the level of protection provided by the sunscreen.

When should you apply sunscreen?

Sunscreen should be applied at least 15 minutes before going out in the sun to allow it to fully absorb into the skin. It should also be reapplied every two hours, or more frequently if you are swimming or sweating.

How should you apply sunscreen?

When applying sunscreen, make sure to cover all exposed areas of skin, including your face, ears, neck, arms, and legs. Be sure to pay special attention to commonly missed areas such as the tops of your feet, the back of your neck, and your scalp if you have thinning hair.

What type of sunscreen should you use?

It is recommended to use a broad-spectrum sunscreen with an SPF of 30 or higher. Broad-spectrum sunscreens protect against both UVA and UVB rays, which can cause skin damage and increase the risk of skin cancer.

By following these guidelines and applying sunscreen correctly, you can help protect your skin from the sun's harmful rays and reduce the risk of sunburn, premature aging, and skin cancer. Remember, sunscreen is just one part of a comprehensive sun protection strategy that should also include seeking shade, wearing protective clothing, and avoiding peak sun hours.
