About This Product.

Every serum, every retinol, every in-clinic treatment you invest in is undermined the moment UV hits unprotected skin. This is the sunscreen that finally removes every excuse not to wear one. Mexoryl 400, La Roche-Posay's proprietary UV filter, protects against ultra-long UVA rays (380-400nm) that most sunscreens miss entirely, the same rays responsible for pigmentation, collagen breakdown and premature ageing. Invisible fluid texture, no white cast, no greasiness, no stinging around the eyes, sits perfectly under makeup or on bare skin. Tested on sensitive, reactive and intolerant skin across all phototypes. Ultra-resistant to water, sweat and sand. The number one dermatologist-recommended sun protection brand in the UK. Also suitable for patients undergoing cancer treatment. If you only buy one skincare product, make it this. 50ml.

How to Take It

i.

Shake well before use. Apply generously to the face as the final step of your morning skincare routine, after serums and moisturiser. Reapply frequently and generously to maintain protection, especially after perspiring, swimming or towelling. Avoid prolonged sun exposure even while wearing sunscreen. Keep babies and young children out of direct sunlight. For use alongside a brightening, retinol or post-treatment protocol, daily SPF application is non-negotiable for maintaining results.

Finally a sunscreen I'll actually wear every day

4 months ago

I've tried so many SPFs over the years that either pill under makeup, leave a white cast, or just feel heavy enough to skip. This one does none of those things. Sinks in within about a minute, sits perfectly under my foundation, and I genuinely forget I'm wearing sunscreen. Been using it every morning for the past couple of months and I'm not going back.

My derm recommended it and she was right

4 months ago

My dermatologist kept telling me my SPF wasn't covering the full UVA spectrum and suggested I look into this one specifically. Swapped over about six weeks ago and the texture really is as good as everyone says — almost like a serum. No stinging near my eyes either, which was always an issue with my old one.

Does exactly what it says. No white cast, no greasy residue, no complaints. Repurchased twice already.

Great SPF, wish the bottle was bigger

6 months ago

The formula itself is genuinely brilliant — lightweight, no cast, doesn't budge in the heat. My only gripe is that 50ml goes faster than you'd expect when you're applying it properly to face and neck every day. I'm getting maybe five or six weeks out of a bottle, which makes it feel a bit pricey for a daily staple. Would love a 100ml option.

Perfect base for retinol users

8 months ago

I started using a retinol last autumn and knew I needed to be much more diligent about sun protection. This fits into my routine seamlessly — goes on after moisturiser, dries quickly, and doesn't interfere with my makeup at all. Skin has stayed even-toned through spring and summer, which is more than I can say for the year before.

Excellent formula, packaging could be better

1 year ago

Really impressed with how this wears — zero greasiness, no white cast even on my deeper skin tone, and it layers well under SPF-containing moisturisers I already use. Docking a star purely because the pump dispenses way more product than you need per use and it's hard to regulate. Ends up being a bit wasteful. The formula itself though, no complaints.
