The Honest Guide to Natural Sunscreen in the UK (2025 Update)

The Honest Guide to Natural Sunscreen in the UK (2025 Update)

Discover what truly makes a sunscreen natural, reef-safe, and good for both you and the planet.

Why Natural Sunscreen Matters More Than Ever

Whether you’re coastal swimming in Cornwall or cycling through Brighton’s South Downs, protecting your skin should never come at the cost of harming the planet. Traditional sunscreens often contain chemicals that damage marine ecosystems and irritate sensitive skin. In contrast, natural sunscreens offer a safer, more sustainable alternative without compromising on protection.

What Counts as "Natural"?

Not all products labelled as natural truly are. Here’s what to look for:

  • Mineral-based protection: Look for non-nano zinc oxide or titanium dioxide, which sit on the skin and reflect UV rays.
  • No harmful chemicals: Avoid oxybenzone, octinoxate, parabens, and synthetic fragrances.
  • Eco-packaging: Choose options in tins, glass jars, or compostable containers.
  • Cruelty-free and reef-safe: Properly certified and not tested on animals.

Alewk.club's Shade All-Natural SPF25 ticks every box and it's made right here in the UK.

Mineral vs Chemical Sunscreen

Feature Mineral Sunscreen Chemical Sunscreen
Active Ingredients Zinc oxide, titanium dioxide Oxybenzone, avobenzone, octinoxate
How It Works Reflects UV rays Absorbs and converts UV rays
Reef-Safe Yes Often no
Skin Irritation Risk Low (especially fragrance-free) Higher, especially with sensitivities
Whitening Effect Slight if not rubbed in well None


Is SPF25 Enough for the British Summer?

Yes, SPF25 blocks approximately 96% of UVB rays, which is often sufficient for day-to-day use in the UK. The key is reapplication every 2 hours, especially after swimming or sweating.

If you have fair or sensitive skin, mineral SPF25 offers a good balance of coverage and skin friendliness especially with non-nano zinc oxide.

Real Talk: Greenwashing vs the Real Deal

Sadly, many brands use buzzwords like “natural” and “eco” without truly walking the walk. To ensure you're buying the real deal:

  • Look for clear labelling of active ingredients
  • Check for independent certifications
  • Avoid vague terms like "plant-based formula" without clarification

Alewk.club takes the guesswork out every product is handpicked for its integrity.

FAQs 

Q: Can I use mineral sunscreen on sensitive skin? A: Absolutely. Look for unscented, non-nano zinc oxide formulas like the one from Shade.

Q: Will natural sunscreen leave a white cast? A: Slightly, but if applied properly (a pea-sized amount warmed between your hands), the effect is minimal.

Q: Is this water resistant? A: Yes, but reapply after swimming, as natural sunscreens don’t contain the same synthetic waterproofing agents.

Q: Is it safe for children? A: Always consult your GP for little ones, but natural, fragrance-free mineral formulas are widely considered safer than chemical alternative
