Even though sunscreen is essential, it doesn’t provide 100% protection against UV rays. So, why is that the case?
The Importance of Proper Application and Duration
SPF 30 blocks 97% of UV rays, SPF 50 blocks 98%, and SPF 100 blocks 99%, providing significant protection. During the summer, opting for SPF 50 or higher provides better protection.
Effectiveness Relies on Correct Usage
Even with proper application, prolonged sun exposure carries risks. In many cases, sunscreen is not applied correctly.
In other words, applying sunscreen and sunbathing does not provide full protection against UV rays.
Determining the Right Amount of Sunscreen
Applying 2 mg of sunscreen per cm2 of the body is ideal. Sources recommend using about 1 teaspoon for the face and neck, or a shot glass amount for the body. However, individual body sizes vary, so these recommendations may differ.
Depending solely on average measurements may not be entirely accurate. For better protection, apply more sunscreen if you can’t measure it precisely each time.
Estimate the suitable amount for your face and neck using your index and middle fingers as a reference.
Additional Considerations for Sun Protection
During the summer, it is crucial to wear UV-protective hats or wide-brimmed hats. If feasible, choose clothing with UV protection.
Moreover, seeking shade rather than direct sunlight is highly recommended, particularly in the summer season.
Don’t forget to wear high-quality sunglasses with UV filters to safeguard your eye health.
Some people still notice skin discoloration and spot reappearance despite sunscreen. This could be attributed the factors I’ve mentioned above.
