5 Common Sunscreen Mistakes: Applying Sunscreen Correctly Maximizes Skin Cancer Prevention

We all know that regularly using sunscreen is one of the best ways to prevent skin cancer. Unfortunately, many people make mistakes when it comes to wearing sunscreen. Properly applying sunscreen and following manufacturer instructions are key to maximum protection.
Common Sunscreen Mistakes

1. Applying sunscreen after going outdoors.

Sunscreen needs to be applied 15 to 30 minutes before going outside to allow it to be absorbed into the skin. Follow manufacturer's instructions for absorption time.

2. Not applying enough sunscreen.

The application estimate is about 1 oz. for an adult. Keep in mind that all body parts that will be exposed to the sun need to be protected. Neglected areas include the face, ears, neck and feet.

3. Not reapplying after swimming.

Sunscreen not labeled "waterproof" or "water resistant" does come off while in the water. Even waterproof and water resistant sunscreen provide a limited time amount of protection. Check the sunscreen label for how often to reapply waterproof and water resistant sunscreens.

4. Not reapplying sunscreen at all.

Many people have the misconception that one application of sunscreen will provide all-day protection. Not true. Sunscreen needs to be reapplied generally every two hours. Check the label for specific instructions.

5. Using sunscreen only when it is sunny.

Sunscreen needs to be used in the sun and in the shade. Harmful UV rays can still affect people when it's cloudy.
