Hot weather calls for serious sun protection.
When the temperature climbs, most of us end up spending a lot more time outdoors, and a lot more time exposed. Every Day Sunscreen SPF 45 - Active is built for exactly those days: SPF 45 broad-spectrum protection that stays comfortable to wear from morning to evening.
Sunscreen works best as part of a broader routine of shade, protective clothing and sensible timing. More on that further down the page.

Many sunscreens can degrade in water. Stream2Sea's patented WetBoost™ Technology has been proven to perform 47% better once you go for a swim, so protection is designed to hold up through the parts of your day that matter most.
Whichever way you spend your time outdoors — swimming, surfing, snorkelling, paddleboarding, hiking, running or simply at the beach — Every Day Sunscreen SPF 45 - Active is formulated to keep up with 80 minutes of water resistance per application.
Serious protection without the heavy, greasy feel.
A sunscreen you'll actually want to reapply is one that doesn't feel like a chore to put on. Every Day Sunscreen SPF 45 - Active is formulated to be lightweight and sheer, so it fits into an everyday routine rather than fighting it.
What's actually in the bottle.
Non-Nano Zinc Oxide
The mineral active ingredient behind the sun protection in this formula, alongside an antioxidant blend that includes turmeric.
Formulated without SLS, parabens or artificial fragrances. Full ingredient list available on the product page.
Protection for you. More consideration for our waters.
Stream2Sea describes its formulas as Reef-Safer™ rather than making an absolute "reef safe" claim. That word choice is intentional — it reflects an ongoing commitment to testing, transparency and continuously working to reduce environmental impact, rather than a guarantee that no impact exists.
Packaging is designed with recyclability in mind as part of the same sustainability approach.

Everything you need to know
Is SPF 45 suitable for a heatwave?
Yes. SPF 45 offers a high level of broad-spectrum UVA/UVB protection, well suited to prolonged time outdoors in hot, sunny conditions. As with any sunscreen, it should be reapplied regularly and used alongside shade, protective clothing and sensible sun exposure timing.
Is Every Day Active a mineral sunscreen?
Yes, it's a mineral-based sunscreen formulated with 19% non-nano zinc oxide.
Is it water-resistant?
Yes, it is formulated to be water-resistant for up to 80 minutes of swimming.
How long is it water-resistant for?
Up to 80 minutes. Reapply after that time, immediately after towel drying, and at least every 2 hours during continued sun exposure.
Is it suitable for swimming?
Yes. It's formulated with patented WetBoost™ Technology, which has been proven to perform 47% better once you go for a swim.
What makes WetBoost™ Technology different?
WetBoost™ is Stream2Sea's patented technology designed to help the formula perform better once it meets water — proven to perform 47% better once you go for a swim, compared to before entering the water.
Is it reef safe?
We describe this formula as Reef-Safer™ rather than making an absolute "reef safe" claim. This reflects our ongoing commitment to testing, transparency and reducing environmental impact.
What does "reef safer" mean?
It means the formulation approach is grounded in testing and continuous improvement to minimise environmental impact, rather than an absolute guarantee of zero impact — a distinction we are deliberate about.
Is it greasy?
No — it's formulated to be lightweight, sheer, non-greasy and non-comedogenic, designed for everyday wear.
What size should I choose?
75 ml suits travel or occasional use, while 470 ml and 960 ml are better suited to regular, everyday or family use across the summer.

Reapply after 80 minutes of swimming or sweating, immediately after towel drying, and at least every 2 hours during continued sun exposure.
How quickly is it delivered in the UK?
UK delivery is typically around 48 hours, with free UK shipping on orders over £25.
Sunscreen is one part of a bigger routine.
For the best protection during hot weather, combine sunscreen with these habits.
- Limit time in the sun, especially between 10am and 2pm
- Wear protective clothing where practical
- Wear a hat
- Wear sunglasses
- Reapply sunscreen every 2 hours, and after swimming, sweating or towelling off
- Seek shade during peak sun hours
Sunscreen use does not eliminate all risk from sun exposure — it's most effective as part of this broader routine.
