As a beauty editor, I’ve tried over 50 sunscreens, from tinted versions to balms, lotions, gels and fluids, with varied success.
As someone with hormonal acne, rosacea, and sensitive skin, I have pretty strict criteria when testing a new one; however, over the past decade, none has remained a permanent fixture like the La Roche-Posay Anthelios UVmune 400 Invisible Fluid SPF50+.
Beloved by beauty editors everywhere, it’s easily one of the best-known, most-used sunscreens on the market, for good reason.

La Roche-Posay Anthelios UVmune 400 Invisible Fluid SPF50+
This fast-absorbing SPF deserves a spot in your skincare routine all year round.
Buy now for £11.96 (was £20)Better yet, thanks to the Amazon Prime Big Deals Day sale, which runs from October 6-7, it’s been slashed in price.
I wear it every day, and it’s the non-negotiable skincare rule I never break, no matter where I’m going or what I’m doing.
Whether it’s pouring down, you’re working from home in your pyjamas or it’s a grey December afternoon in the office, UVA and UVB rays can still get through, and a good SPF can protect your skin from skin cancer, fine lines and wrinkles, pigmentation and collagen depletion.
There’s a reason this is loved by thousands. (Picture: Metro/Amazon)But I don’t just love the La Roche-Posay Anthelios UVmune 400 Invisible Fluid SPF50+ because it provides high protection; it’s a lightweight, fluid formula that I actually like wearing.
It doesn’t leave my face sticky, greasy, or with a white cast, and it doesn’t take ages to rub in or start peeling off under makeup. Instead, it has a runny, almost watery texture that massages into a clear, invisible finish that’s great for keeping an oily T-zone like mine at bay, and never, ever irritates my acne or rosacea.
It takes about 10 seconds to fully absorb, so you don’t need to wait to apply your makeup; it glides on with no bother. Just make sure to shake it before you use it.
It’s a broad-spectrum formula, meaning it protects you from UVA and UVB rays, with its key ingredient being Mexoryl 400, which provides advanced protection against ultra-long UVA rays, AKA the ones that penetrate deeper into the skin and can cause premature ageing.
We always use Prime Day to stock up on our fave SPF. (Picture: Metro/Amazon)Unsurprisingly, it’s a huge hit among Amazon shoppers, with 10,000 people having bought it in the last month alone.
If I’ve not convinced you, here are a few reviews that will definitely win you over. One customer called Marc wrote: ‘I’ve been using the La Roche-Posay Anthelios UVMune 400 SPF50+ for around two months now and I’m really impressed with it. The invisible fluid is lightweight and easy to apply, and it doesn’t feel heavy or overly greasy on my skin. It also absorbs well without leaving an obvious white residue, which is one of the things I look for in a facial sunscreen.’
Meanwhile, another shopper called Mae said, ‘This sunscreen leaves no white cast. No grease or streaks. It feels smooth and moisturising. It dries fast, and it has no strong alcohol or unpleasant smell as many sunscreens do.’
Now it’s on sale; there’s no reason not to add it to your basket. It’s one of those rare sunscreens you’ll actually want to wear, and your skin will be much better off with it than without it.
