Mineral vs chemical sunscreen - how to choose a safe natural sun protection

The sun is shining again – the perfect time to update your sun protection to a cleaner, more natural choice. Mineral sunscreens (also known as physical sunscreens) are becoming increasingly popular – and for good reason. In this blog, we explain the key differences between chemical and mineral sunscreens so you can make an informed and skin-friendly choice for safe, natural sun protection.

What is mineral sunscreen?

Unlike chemical sunscreens, mineral sunscreens help protect the skin by reflecting and scattering UV rays using natural minerals such as zinc oxide and titanium dioxide. They offer broad-spectrum protection and are often well tolerated by sensitive skin. Mineral formulas are also considered a more ocean-friendly option.

Why many people prefer mineral over chemical sunscreens

Many conventional sunscreens use chemical UV filters such as oxybenzone and octinoxate, which absorb the sun’s rays and convert them into heat. While effective, some of these ingredients have raised environmental concerns, particularly regarding coral reefs and marine ecosystems.

  • Oxybenzone and octinoxate have been banned in places like Hawaii, Palau, and Thailand due to their toxic effects on coral reefs and marine life.
  • Studies have also linked oxybenzone to potential hormone disruption, thyroid issues, and even changes in pubertal timing.

Because of these risks, many dermatologists and eco-conscious consumers now recommend safer alternatives, like mineral-based sunscreens, which are not only effective but also kinder to your body and the planet.

When should you use sunscreen?

Dermatologists and health authorities recommend using sunscreen whenever the UV index is 3 or higher. At this level, UV radiation is strong enough to cause skin damage even on cooler or cloudy days.

In Southern Europe, the UV index often exceeds 3 for most of the year, which means daily sun protection is recommended – not only at the beach, but also during everyday activities such as walking, driving, or sitting outdoors.

SPF 30 vs SPF 50 – What is the difference?

The SPF number (Sun Protection Factor) tells you how well the sunscreen protects your skin from UVB rays:

  • SPF 30 blocks about 97% of UVB rays
  • SPF 50 blocks about 98% of UVB rays

SPF 50 provides extra protection for very fair, sensitive, or sunburn-prone skin, especially during prolonged sun exposure (like at the beach or during outdoor sports).

SPF 30 is perfect for daily use when sun exposure is moderate or when your skin is already a bit sun-acclimated.

Zinc Oxide – modern and elegant

In the past, zinc oxide sunscreens were known for their thick texture and visible white cast. Today, modern formulations use micronized non-nano zinc oxide to create lightweight, comfortable protection with minimal whitening. This allows you to enjoy effective broad-spectrum protection – including from UVA rays – without a heavy or greasy feel.

Mineral sunscreen for children and babies

Children’s skin is thinner and more delicate, so gentle sun protection is essential. Mineral sunscreens are often recommended for kids because:

  • They start protecting immediately after application
  • They don't contain chemical UV filters that may irritate delicate skin or affect hormones
  • Zinc oxide forms a protective barrier on the skin’s surface

Beachkind Sensitive SPF50 is fragrance-free and formulated especially for babies and children – offering high protection without unnecessary additives.

Please note: babies under 6 months should be kept out of direct sunlight and protected with shade and clothing rather than sunscreen.

Sunscreen during pregnancy

During pregnancy, it is recommended to use only physical (mineral) sunscreens, as they do not penetrate the skin. Beachkind SPF 50 Sensitive is 100% mineral-based, making it a safe and trusted choice for sun protection during pregnancy. It contains no fragrances, hormone-disrupting chemicals, or synthetic UV filters – only gentle, effective protection for you and your baby.
