Timing is everything when it comes to sunscreen application. Many people apply sunscreen just before sun exposure, not realizing that it takes about 15 minutes for the skin to absorb and activate the protective ingredients. This delay can leave skin vulnerable to UV damage. To maximize protection, apply sunscreen at least 15 minutes before going outside. This allows the active ingredients to form an effective barrier against UV rays. By incorporating this simple habit into your routine, you can significantly enhance your sun protection strategy.

4. Quantity Matters: The Shot Glass Rule

One of the most common sunscreen mistakes is under-application. Dermatologists recommend using about one ounce, or a shot glass full, to cover the entire body. Many people apply only a fraction of this amount, reducing the effectiveness of the sunscreen. To ensure complete protection, be generous with your application. This means using enough product to cover all exposed skin, including often-missed areas like the ears, neck, and tops of feet. By adhering to the shot glass rule, you can prevent sunburn and cumulative skin damage, turning a common slip-up into a skincare strength.
