Sunscreen has become an essential part of every trip to the beach. However, according to experts, many people are not protecting their skin as well as they think—not because they choose the wrong product, but because they use it incorrectly.
Many people apply sunscreen only after arriving at the beach or just before getting into the water. In reality, sunscreen needs time to absorb into the skin and form its protective barrier. Dermatologists recommend applying it about 20 to 30 minutes before sun exposure to ensure maximum effectiveness.
Why Protection Is Reduced
If someone heads straight into the sun or jumps into the sea immediately after applying sunscreen, the product has not had enough time to set. Some of it is removed by sweat, while water further reduces its effectiveness, leaving the skin exposed to harmful UV rays.
As a result, the actual level of protection may be much lower than the SPF listed on the packaging, experts warn.
The Second Major Mistake: Using Too Little
Another common mistake is applying far less sunscreen than is actually needed. Experts say an adult should use about one full shot glass of sunscreen to cover the entire body, along with an adequate amount for the face, ears, and back of the neck.
When only half the recommended amount is applied, the effective SPF drops significantly, leaving the skin much more vulnerable to the sun’s rays.
Why Reapplication Matters
Even water-resistant sunscreens do not provide all-day protection. Experts recommend reapplying sunscreen every two hours, as well as after swimming, heavy sweating, or towel drying.
Prolonged exposure to ultraviolet (UV) radiation is associated with sunburn, premature skin aging, dark spots, wrinkles, and an increased risk of skin damage. For that reason, using sunscreen correctly is just as important as choosing the right SPF.
