In summer, we naturally spend more time outdoors and enjoy longer days in the sun. However, protecting your skin is just as important as enjoying the warmer weather. To make sure your daily routine provides the protection you need, it’s worth knowing the most common mistakes people make when applying SPF.
TOP 5 mistakes when using sunscreen
To avoid sunburn, skin damage, pigmentation, or premature aging, you must choose the right sunscreen and use it correctly. In this article, we discuss the TOP 5 mistakes made when using sunscreen and explain why people repeat them when trying to protect their own and their children’s skin from harmful UV rays.

Using too little product
One of the most common mistakes is using too little sunscreen. For effective protection, an adult should apply about two fingers’ length of cream just for the face, neck, and ears. If you use less, the effectiveness of the sunscreen or lotion drops significantly.
Many people avoid using enough sunscreen because it absorbs poorly or leaves white marks. Therefore, choose a product with a texture that allows easy application of the right amount. For example, Dermedic Sunbrella SPF 50+ hydrating sunscreen is light, spreads easily, and does not leave white streaks. This makes it convenient for daily use.
Sun protection is used only when it is sunny
Many people use sunscreen only on hot, sunny days and during summer. However, UV rays reach you even through clouds and windows – whether driving or working by a window. This applies in winter and summer, at the beach or skiing in the mountains.
Always include sunscreen in your daily morning routine, no matter the weather. Lightweight products like Dermedic Sunbrella ultra light SPF 50 are perfect for daily use, even under makeup. We love Dermedic Sunbrella ultra light fluid – its water-based texture is designed to protect sensitive, dry, and normal facial skin from the full spectrum of sunlight. It is very lightweight, deeply hydrates, absorbs quickly, and does not leave a white film. Additionally, it soothes the skin.
Not reapplying sunscreen
Applying sunscreen once in the morning is not enough. Especially if you sweat, swim, or rub your face with your hands or clothes. It is essential to remember this when spending time at the sea or by the water. Even if the sunscreen is water-resistant, you still need to reapply after swimming or after some time outdoors.
If you spend the day outside or by water, play sports, or walk – remember – it is important to apply sunscreen every 2–3 hours. Take a spray sunscreen with you for quick and easy reapplication. For kids, we use Dermedic Sunbrella baby milk in spray, which offers very high, effective, and long-lasting protection against UVA, UVB, VL, and IR radiation. We also use Dermedic Sunbrella sun protection spray ourselves, which provides comprehensive protection against UVA, UVB, VL, and IR radiation while in the sun.
Choosing the wrong sun protection product
People with oily or sensitive skin often avoid rich, heavy, or scented sunscreens. As a result, protection becomes irregular or is forgotten.
Pick products suited to your skin type. Dermedic Sunbrella offers sunscreens in fluid form for dry and normal skin as well as oily and combination skin.
Sunscreens for adults are not suitable for babies and children. To protect your child’s skin, choose Dermedic Sunbrella Baby line. It is designed for sensitive or infant skin – fragrance-free and made with thermal water.
Not applying sunscreen to the neck, ears, lips, or hands
We try to protect our face but often forget other sensitive areas, such as the neck, décolletage, ears, hands, and lips. These zones also receive a lot of UV rays. Therefore, it is crucial not to forget to protect them as well.
Remember – even the best sunscreen will not work if you use it incorrectly. To protect your skin from harmful UV rays, you must choose a quality product and know how, how much, and when to use it. Dermedic offers dermatologically tested products for different skin types. They let you care for your skin safely and reliably every day.
