La Roche Posay UVMune 400 Invisible Fluid Review: with a new filter Mexoryl 400 claiming to have the best UVA spectrum protection out there. It’s easy to purchase in Europe, and still relatively affordable. Everyone seemed to love it, but how does it compare with other sunscreens? With filter low-down & checklist!

My skin is medium dark tone, Fitzpatrick IV, with an extreme combination (prone to dry patches). I enjoy spending time in the sun, doing outdoor activities like running and hiking, although I don’t enjoy sunbathing per se. I prefer my sunscreens not sticky.

The Product

The La Roche Posay Brand

La Roche Posay is a French brand, which is also the name of the city it’s from. Founded in 1975 by Monsieur Levier, it is currently under L’Oreal group, and it’s famous for products suited for problematic skin.

Note: I am surprised that we have reviewed none La Roche Posay’s sunscreen on the site.

La Roche Posay

The most exciting thing with this sunscreen is the new sunscreen filter, Mexoryl 400, that should protect well against the Ultra Long UVA (Why UVA protection matters). The exact PPD number of this product hasn’t yet been published officially, but the previous version has PPD of 46.

La Roche Posay UVMune 400 Invisible Fluid Application

The sunscreen on the scale, 0.04oz
The sunscreen on the scale, 0.04oz

The texture is very liquid, almost water-like. There’s no way you can do a finger-length application, because it will slide off your fingers as soon as you put it there.

This 0.04 oz is equal to 1/4 teaspoon.

On My Hand

Here you can see the texture is very runny. It is quick to spread and quick to absorb. There are no white cast, but there is a slight visible shine on my hand.

On My Face

What I love: super easy to apply and reapply. What I don’t love: it still feels like something on the skin.

Claim Check on LRP Anthelios UVMune 400 SPF 50+

The claim check is based on my experience only, and it might not be the ultimate truth for everyone.

Ultra resistant: water, sweat, and sand resistant

I couldn’t properly test the water resistant feature yet, as I haven’t been able to go swimming this season. But I used this sunscreen when I went on a hiking trip at Cinque Terre.

I only reapplied once throughout the day (texture is still as pleasant on my skin after re-application), and I noticed a bit of redness on my skin. The weather was super sunny with little shades and lots of wind.

Anti eye stinging

Yes. I’m not sure what the “anti” supposedly meant. However, this sunscreen doesn’t sting my eyes at all.

Invisible

Yes, for a medium dark skin tone. (Fyi, this sunscreen has a yellowish tone, it’s invisible on me, but might have an effect if you have a very light pink tone).

Light weight texture

Well, kinda. The consistency is the most runny of all sunscreens I’ve tried, and yet it doesn’t feel like that on application. It does make it easy to apply the quarter teaspoon though.

Non greasy

Unfortunately not. It really depends on what you wear underneath, and even then, I wouldn’t call it non-greasy. It is, however, less greasy than most other sunscreens out there.

LRP Anthelios UVMune 400 Invisible Fluid Review

Face Routine

Toner and very light serum.

Piling

Never happened on my skin.

Feel on Skin

It is very watery, sinks in quickly with no white cast, but there is a slight sticky feeling afterwards.

Scent

No Fragrance and no prominent smell.

Stings the Eyes / General Discomfort

None.

Comparison

Comparing texture between Invisible Fluid and Anessa
Comparing texture between La Roche Posay UVMune 400 Invisible Fluid and Anessa Skincare Milk

The texture is the most watery from all the sunscreens I’ve tried so far. Even compared to Anessa’s it looks like it would disperse easily on the surface. Combined with the absolute no white cast feature, it makes it one of the easiest sunscreen to wear.

Anessa’s Perfect UV Sunscreen Skincare milk still has the best texture when I want to layer makeup on it, Garnier Super UV Face Fluid is pretty similar to this one but slightly less greasy.

Checklist & Rating:

Alcohol is the ingredient number two for this sunscreen. Take my thought with a grain of salt because my skin is not especially sensitive to it, but this is the least drying of all the other ones I’ve tried with alcohol in it, including the Biore Aqua Rich.

La Roche Posay Anthelios UVMune400 Rating
La Roche Posay Anthelios UVMune400 Rating

It really is an almost perfect sunscreen, especially if you count the waterproof and sweat resistant claims. It would be the one I’d bring to a summer vacation on the beach if I can only bring one sunscreen.

Verdict:

skincare rating

It’s between like and love for me. It still has room for improvement, so maybe if it’s discontinued, a better version will come along too.

Reasons I love it on La Roche Posay UVMune 400 Invisible Fluid Review:

  • Relatively easy to get where I live (Germany)
  • Bottle is super easy to carry around
  • Very pleasant to apply and reapply
  • The promising new sunscreen filter for ultra long UVA

I don’t think you can go terribly wrong with this one. It’s not the best sunscreen I have, but it’s really close.
