Waterproof sunscreen – how safe are you really when swimming?

Summertime is swimming time. Whether at the sea, a lake, or an outdoor pool – water has a magical attraction for us. But it is precisely there that our skin is particularly challenged.

Why? Because water reflects sunlight and intensifies its effect. A waterproof sunscreen sounds like the ideal solution. But what exactly does "waterproof" mean? And how long does the protection really last?

What does "waterproof" mean in relation to sunscreen?

Waterproof means: limited protection when in contact with water

Just because sunscreen is labelled "water-resistant" doesn't mean it's invulnerable after the first dip in the water. According to EU standards, at least 50% of the original sun protection factor must remain after two 20-minute swims.

What is the deal with the sun protection factor?

The sun protection factor – abbreviated SPF – indicates how much longer you can stay in the sun with sunscreen without risking sunburn.

An SPF of 50, for example, means that your skin is theoretically protected 50 times longer than without protection. However, it's important to know that the sun protection factor primarily refers to UVB rays – those that cause sunburn. For comprehensive protection, you should ensure that your sunscreen also protects against UVA rays, as these penetrate deeper into the skin and accelerate skin aging.

Why reapplying cream is so important

Renew UV protection – even for “waterproof” products

Waterproof means the protection lasts longer, but it certainly doesn't last indefinitely. The combination of chlorine, salt, sand, and friction from towels gradually reduces the protective effect. Therefore, you should follow these tips:

• Reapply cream every two hours

• Apply cream again after every bath,

• Apply a new layer even after drying or heavy sweating.

Sun-stressed skin requires special attention.

Moisture and antioxidants

Modern sunscreens and sprays often offer more than just UV protection. They provide your skin with nourishing ingredients that soothe it and protect it from drying out.

Typical ingredients with added value for the skin:

• Hyaluronic acid : retains moisture and plumps up the skin.

• Vitamin E : protects against free radicals

• Aloe Vera : has a soothing and anti-inflammatory effect

Our newkee sunscreen, especially the SPF 50+ face cream , contains aloe vera. The sunscreen is vegan and also moisturizes the skin. Furthermore, newkee sunscreen is free of harmful substances, microplastics, silicones, parabens, perfume, and fragrances.

Important: Choose a sunscreen that not only protects but also suits your skin type – especially if you have sensitive or dry skin. If you have baldness or thinning hair, you should be particularly careful with sun protection. Lips and ears are also often forgotten areas that are especially prone to sunburn.

How to apply sunscreen correctly: This is how it works.

The basics: quantity, timing, technique

The sun protection factor only works if the cream is applied correctly. This means:

• Apply generously : approximately one shot glass (30 ml) for the entire body.

• Cover areas : Don't forget ears, neck, backs of hands and feet.

• Apply sunscreen early enough : ideally 20 to 30 minutes before sunbathing.

• Reapply regularly : at least every two hours – and always after bathing

By the sea? Then double protection is needed.

Increased radiation due to water and sand

At the beach, sun, wind, and water all affect your skin simultaneously. UV radiation is more intense there – and the need for protection increases.

What you need:

• Waterproof sunscreen with a high SPF (30 or higher)

• Light clothing that covers your skin

• Shade , especially at midday (11am–3pm)

• Sun hat and sunglasses with UV filter

The combination of mechanical protection and regular reapplication of cream is your reliable companion for a healthy day at the beach.
