Sunscreen is one of the most effective tools in protecting your skin from the harmful effects of UV radiation, yet many people still make critical mistakes when applying it. These errors can diminish its effectiveness and leave you vulnerable to sunburn and long-term skin damage. Below are five common mistakes people make when applying sunscreen and tips on how to avoid them:
- Applying too little sunscreen
One of the most frequent mistakes is not using enough sunscreen. Most people apply a thin layer, which doesn’t provide adequate protection. Dermatologists recommend using about a shot glass full (approximately two tablespoons) for your entire body. For your face alone, a nickel-sized amount is usually sufficient. Ensure that you cover all exposed areas, including the ears, back of the neck, and the tops of your feet.
- Applying sunscreen only once a day
Many individuals apply sunscreen only once in the morning and assume it will last all day. However, sunscreen can wear off due to sweating, swimming, or towel drying. To maintain optimal protection, reapply sunscreen every two hours, or more often if you are swimming or sweating heavily. If you’re using a water-resistant sunscreen, check the label for specific instructions on reapplication.
- Relying solely on sunscreen
Sunscreen should be part of a broader sun protection strategy, not the only line of defence. Wearing protective clothing, seeking shade, and avoiding peak sun hours (10 a.m. to 4 p.m.) can significantly reduce your risk of sun damage. Additionally, hats and sunglasses with UV protection can shield sensitive areas like your eyes and face.
- Ignoring expiry dates
Sunscreen has a shelf life, and using expired products can result in reduced effectiveness. Check the expiry date on the packaging and avoid using sunscreen that is past its prime. If your sunscreen doesn’t have an expiration date, it’s generally safe to use for up to three years from the date of purchase, provided it has been stored correctly. If it changes in texture, colour, or smell, it’s time to replace it.
- Applying sunscreen too late
For maximum effectiveness, sunscreen should be applied about 15 to 30 minutes before sun exposure. This allows the product to fully absorb into the skin and form a protective barrier. If you wait until you’re already outside, the sunscreen might not offer full protection from the start, leaving you exposed to harmful UV rays.
Tips for Proper Sunscreen Application:
- Choose the right SPF: Opt for a broad-spectrum sunscreen with an SPF of 30 or higher. Broad-spectrum protection ensures coverage against both UVA and UVB rays.
- Follow instructions: Always read and follow the instructions on your sunscreen’s label for the best results.
- Be consistent: Make sunscreen application a daily habit, even on cloudy days or when indoors, as UV rays can penetrate through windows.
By avoiding these common mistakes and following these tips, you can enhance the effectiveness of your sunscreen and better protect your skin from the sun’s damaging rays.
