Sunscreen formulas today are more lightweight than ever before, and when it’s time to buy a new bottle of SPF, we’re on the lookout for ones that not only protect, but also feel great on the skin.

Of the many lining the shelves at drugstores, La Roche-Posay’s sunscreens are ahead of the game with their high protection formulas that wear comfortably on the skin.

The brand’s iconic Anthelios line features 17 amazing sunscreens, including the newest kid on the block, the La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50+!

Since we’re picky about our sunscreen choices, we tested the Anthelios UVMune 400 Invisible Fluid SPF50+ for ourselves and, spoiler alert: it’s one that feels and works well. Don’t just take it from us, take it from the 10 readers who tested this sunscreen for a week before sharing their reviews.

La Roche-Posay’s skincare formulations are recommended by over 90 thousand dermatologists worldwide for being effective and well-tolerated by even sensitive skin, and their sunscreens are no exception.

The Anthelios UVMune 400 Invisible Fluid SPF50+, like its predecessors, offers broad-spectrum “very high” UVB/UVA protection.

However, La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50+ is not quite the same as the rest of the Anthelios sunscreens.

This one’s further upping the ante on sun protection with the newest patented UV filter in the L’Oreal Group, the Meroxyl400 – it’s the first in the L’Oreal group to be using this sun filter.

What’s special about Meroxyl400 is that it shields the skin from ultra-long UVA (ultraviolet A), the longer wavelength of ultraviolet light associated with skin ageing.

Ultra-long UVA, according to La Roche-Posay, refers to the UV rays that are between 380nm to 400nm in wavelength. UVB, short UVA, and long UVA make up 70% of total UV rays, and ultra-long UVA contributes to a significant 30%. Moreover, these UVA rays can penetrate windows, and reach our skin even when we are indoors.

As research shows that sun exposure (including to UVB, UVA, and ultra-long UVA) is responsible for an estimated 80% of visible skin ageing effects, this Meroxyl400-equipped sunscreen should further defend your skin against signs of ageing.

Finally – and this one’s a big criterion for us – this sunscreen is powered by Netlock Technology. It gives the sunscreen a lightweight, invisible texture, and extra resistance against water, sand, and sweat!

Created for those with sensitive and reactive skin, the sunscreen is even offered by the brand as suitable protection for those who have sun-allergic skin.

Whether cosy indoors or having fun under the sun, we’re sporting our Anthelios UVMune 400 Invisible Fluid SPF50+ sunscreen and putting it to the test.

Writer’s review of La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50+

If there’s anything that I’m particular about when it comes to skincare products, it’s how they feel on my skin. I need products that are lightweight, non-greasy, and feel like they’re not really there – the same goes for sunscreen too.

The sunscreen that I was using prior to the trial is super lightweight and absorbs fast. So, when I was asked to try the La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50+, I didn’t expect much. I mean, could another product beat how water-light my everyday sunscreen felt on my skin?

Keep reading for my full review!

Feel and finish of the sunscreen

Before (top) and after (bottom) spreading the sunscreen over my skin

The La Roche-Posay Anthelios UVMune 400 Invisible Fluid dispenses a watery, silky, white fluid from the narrow tip of its slim bottle. Due to its watery nature, it can be slightly messier compared to other sunscreens.

However, that’s just a tiny drawback because the sunscreen is easy to apply and feels comfortable on the skin too.

When you spread it out evenly, its white appearance disappears, leaving no cast on the surface. The product also feels surprisingly lightweight and non-greasy.

As lightweight as the sunscreen is, it still forms a layer of protective film on top of your skin. It really does feel as if the sunscreen adheres to the surface of the skin and doesn’t budge easily.

Effectiveness of the sunscreen

When I put it to the test, the La Roche-Posay Anthelios UVMune 400 Invisible Fluid really did prove to be more lasting than other SPF products.

I wore the sunscreen to the beach twice, and both times, the product didn’t melt away when my skin touched the water, unlike the body sunscreens that I typically wear for outdoor activities.

I also didn’t get a sunburn after several hours under the relentless afternoon sun, which was a big deal considering that my skin gets sunburnt easily.

The sunscreen’s water-resistant and powerful UV filter claims really did seem to be holding up. Still, I couldn’t know for sure whether the sunscreen was indeed “ultra-resistant” to water, which is why I brought out a UV camera to check the next day.

Water resistance of the sunscreen

I applied the La Roche-Posay Anthelios UVMune 400 Invisible Fluid all over my face and looked at myself through the UV camera. The areas that had sunscreen showed up dark.

I reapplied sunscreen only on my face for this test

For those who are unfamiliar with how it works, a UV camera captures light from the ultraviolet spectrum. Since a sunscreen absorbs ultraviolet rays, it turns up on the UV camera in a darker shade, allowing you to observe where on your body the sunscreen is.

Before and after splashing water on my face

After applying the sunscreen, I splashed water over my face, and then checked using the UV camera again. The sunscreen still appeared in darker hues in the same areas that I had applied it.

So, was the La Roche-Posay Anthelios UVMune 400 Invisible Fluid an “ultra” water-resistant sunscreen? It seemed so.

Overall verdict

Although lightweight was what I was looking for in a good sunscreen, the La Roche-Posay Anthelios UVMune 400 proved to be so much more than that.

It’s a sunscreen that really stays on your skin, and is effective at protecting the skin from the sun’s harsh rays. It goes well under makeup too. You could say it’s a sunscreen that protects you from everything under the sun!

Even after my one-week trial, I’ve continued to use it long after that. I’m even confident enough to say that I would use it daily in place of my long-time go-to sunscreen.

Jia Li, 26

Skin type: Combination-oily, sensitive

“The sunscreen felt extremely lightweight on the skin without over-drying it. It also absorbed quite fast – you could still feel that product there but it didn’t feel too much on the skin.

I also liked that it felt comfortable around the eye area. I usually apply sunscreen around that area to prevent sun damage as I tend to get dark eye circles easily.”

Jia Li jogged in the mornings on some days and did HIIT in the evenings. This was her experience with the sunscreen during her sports activities:

“It was more lightweight and didn’t leave white streaks when I exercised. My sweat didn’t mix with the sunscreen at all which I really liked as sometimes sunscreen can get mixed in sweat and sting my eyes.

I have sensitive skin that can sometimes get red when I sweat, so I really liked the sunscreen’s lightweight texture because it really allowed my skin to breathe.

I also found that my face didn’t get as red after exercising, and I didn’t look significantly tanner after being under the sun. I enjoyed using this product!”

Anthelios UVMune400 Invisible Fluid Review (8)

“The product has a nice unique fluid and lightweight texture compared to other sunscreens I’ve tried. It absorbed well into my skin and did not feel greasy at all. It also left no appearance of white marks.

With its lightweight texture, it did not clog my pores or cause breakouts. My skin did not feel irritated. I also like that it is not heavily scented, which was great for my sensitive skin.

My skin felt hydrated and I had less redness on my face during the day. I definitely would consider using the product again.”

Yongxi, 39

Skin type: Combination-oily, sensitive

“It has a light texture and does not leave my skin looking white or greasy. In fact, the sunscreen was absorbed into my skin within seconds, and even left my skin feeling hydrated.

The La Roche-Posay Anthelios UVMune 400 Invisible Fluid is good for my sensitive skin because it didn’t cause irritation or any breakouts.

It had a clean finish and was comfortable on my skin. I prefer this brand because of its texture and feel.”

Joycelyn, 28

Skin type: Combination-oily, sensitive

Anthelios UVMune400 Invisible Fluid Review (9)

“I have been using my current sunscreen for three to four years and couldn’t find other products that could replace it.

I’m really glad that I came across this product, because the La Roche-Posay Anthelios UVMune 400 Invisible Fluid is exactly what I’ve been looking for: watery texture, lightweight, and absorbs easily.

The sunscreen is extremely fluid with an appropriate amount of thickness. It spreads easily across the skin, gets absorbed quickly and doesn’t “ball up” when layered on top of my skincare routine. Once it settles, it feels like the skin has been enveloped in a thin, non-sticky protective film.

On top of that, it has some oil-controlling properties that work well for my skin. I’ve noticed I look less oily after a long day with this product compared to other sunscreens.

I will be replenishing this once I’ve finished my current bottle.”

Xaveir, 22

Skin type: Combination-oily, sensitive

“I really like it! It is a very fuss-free sunscreen and works very effectively. I really like that it’s super compatible with my skin and spreads really well. A lot of sunscreens tend to tug the skin and make it very difficult to spread.

I went to the gym, and wearing this sunscreen didn’t make my skin feel stuffy, even after I’ve sweated. The brand is also known to not irritate the skin, hence I really enjoy this product a lot!”

Leona, 29

Skin type: Combination-oily, sensitive

“The sunscreen is quite watery, lightweight and blends easily, leaving no white cast. I like this as it’s easy to apply.

I used two finger lengths worth of sunscreen to cover my whole face, and I did not experience any piling when applying the product. The sunscreen also goes well under my makeup, and leaves my skin feeling hydrated too.

The La Roche-Posay Anthelios UVMune 400 Invisible Fluid has worked very well for my skin type, and I would recommend it!”

Kelly, 25

Skin type: Combination-oily

“I love how La Roche-Posay Anthelios UVMune 400 Invisible Fluid has a runny texture, which makes it easy to apply. It’s super absorbent and lightweight.

It also doesn’t leave a white trace on my skin after application, and absorbs almost instantly to form an invisible shield to protect my skin.

I walk a lot and, hence, sweat a lot too, but the sunscreen doesn’t feel heavy on my skin or leave white marks.

The box-like, sleek design of the product makes it easy to carry around, even when I am carrying a smaller handbag.”

Karin, 36

Skin type: Combination-oily

“Initially, I was apprehensive about the watery texture and I was afraid it would be greasy. I was surprised that, while watery, it is easily applied and absorbed into the skin.

It didn’t cause any breakouts and felt comfortable on the skin even when I reapplied it throughout the day. I also like the sleek packaging as it is convenient to bring out for reapplication.

My overall experience was pleasant and I have already recommended it to my friends!”

Shirlyn, 29

Anthelios UVMune400 Invisible Fluid Review (8) (1)

“It feels very good and comfortable on my skin like it isn’t there. I applied two 50 cents coins worth of sunscreen on my face, neck, and shoulders. I was under the sun for the whole day in the pool, yet I did not get any sunburn!

I love it. The product is very well-packaged, light and handy, and very comfortable on my skin.”

Luna, 25

Skin type: Oily

Anthelios UVMune400 Invisible Fluid Review (10)

“I love this sunscreen! Its liquid-like texture is very different from most other sunscreens I’ve tried. It was easy to use and never felt sticky on top of my moisturiser.

The product absorbed quickly, was non-greasy, and never felt heavy on my skin. It was like wearing a second skin – I nearly forgot it was on!

I went for a jog in the evening, and the sunscreen did not streak in contact with my sweat. Overall, it was really nice to use.”
