La Roche-Posay Anthelios Invisible Fluid SPF50+

A first impression

The single most useful thing in the bathroom of anyone who has lived long enough to know better. Anthelios UVMune 400 is the sunscreen La Roche-Posay spent a decade reformulating – and the one your dermatologist will tell you to wear every day, whether or not you feel like it.

Why eMaison chose it

Two things are true about skin after forty. The first is that pigmentation, fine lines and loss of firmness are mostly – unromantically – photodamage. The second is that no skincare hero matters more than daily, high-factor, broad-spectrum sun protection. UVMune 400 is built around Mexoryl 400, La Roche-Posay's patented filter that covers the far end of the UVA spectrum (380–400nm) which most sunscreens still miss. That range is what quietly drives hormonal pigmentation; so if you are investing in Vinoperfect or any acid-led serum, this is the insurance the rest of your routine depends on.

How it fits into your rituals

Morning, after moisturiser, as the final step before makeup. Two fingers' worth for the face and neck – more than feels polite, which is the point. Reapply every two hours if you are outdoors, or once at lunchtime for a day at your desk by a window. The fluid is dry-touch, fragrance-free and sits invisibly on most skin tones. In high summer, pair it with a hat. The rest of the year, it does everything a sunscreen needs to.

What's in it

Mexoryl 400, the exclusive long-UVA filter. A considered stack of filters working together for broad-spectrum protection. Fragrance-free. Contains alcohol denat (which gives the finish, but may not suit the most reactive skin).

The honest note

You will wear this every morning or you will not. Nothing else you own will matter as much.
