UVMune 400 Sunscreen SPF 50+

The 400 in the name is the whole point.

Most sunscreens stop protecting somewhere around 380 nanometres. The range between 380 and 400 is ultra-long UVA — the deepest-penetrating light of the lot, and the part responsible for most of the ageing you'd otherwise be paying to treat.

UVMune 400 filters all of it. That gap is the difference between protecting your skin and mostly protecting it.

What it's like to actually wear

No white cast. Chemical filters rather than mineral, so nothing grey on olive or deeper skin.

Non-perfumed. Fragrance is the most common irritant in sunscreen and the reason most people quietly stop wearing theirs.

Doesn't sting your eyes. Formulated specifically to avoid it, which anyone who's worn sunscreen in the heat will recognise as unusual.

Hydrating cream texture with 24-hour hydration. Sits under makeup without pilling.

Water and sweat resistant. Formulated for sensitive skin.

How to use

Last step of your morning routine, after moisturiser and before makeup.

Roughly two fingers' length for face and neck — most people use less than half what they should, which is how an SPF 50 ends up performing like an SPF 15. Reapply if you're outside for long stretches.

50ml. Made in France.

Worth knowing

Sunscreen is the only skincare product with a genuinely settled evidence base behind it. Everything else you own is doing something incremental. This one is doing the heavy lifting.
