La Roche-Posay Anthelios UVMUNE 400 Invisible Fluid SPF 50+
Available in stock (25)
UVA rays between 380-400nm penetrate deeper than you think. They slip past most sunscreens and trigger the cellular damage behind dark spots and premature aging. La Roche-Posay Anthelios UVMUNE 400 Invisible Fluid was built to stop them with Mexoryl 400, the filter that blocks the longest, most damaging wavelengths other formulas miss.
Key Benefits
- Mexoryl 400 filter technology: captures ultra-long UVA rays (380-400nm) that cause deep cellular damage and photoaging
- SPF 50+ broad-spectrum shield: blocks UVB rays that burn skin and UVA rays that break down collagen year-round
- Invisible, non-greasy finish: absorbs instantly with zero white cast, layers seamlessly under makeup
- Water and sweat resistant: Netlock technology keeps protection intact through swimming, perspiration, and sand exposure
- Anti-eye-stinging formula: dermatologist-tested comfort for sensitive skin, safe for reactive and sun-intolerant faces
- Lightly fragranced fluid: subtle scent makes daily SPF feel less clinical, more like part of your routine
Key Ingredients
Mexoryl 400 (Methoxypropylamino Cyclohexenylidene Ethoxyethylcyanoacetate): La Roche-Posay's patented UV filter that blocks ultra-long UVA rays (380-400nm), the hardest wavelengths to stop and the ones most responsible for deep DNA damage. Netlock Technology: a film-forming polymer network that locks filters onto skin, keeping your SPF shield intact even when wet or sweating. La Roche-Posay Thermal Spring Water: selenium-rich soothing water that calms sensitivity and strengthens your skin barrier against environmental stress.

How to Use
How to Use
Apply generously to your entire face every morning, from your hairline to your jawline. Use it 15 minutes before sun exposure. Smooth it on as the final step of your skincare routine, after moisturizer and before makeup. Reapply every two hours during extended outdoor time, and immediately after swimming, towel-drying, or heavy sweating. Do not apply directly to eyes.
Frequently Asked Questions
Frequently Asked Questions
Is La Roche-Posay Anthelios UVMUNE 400 a mineral sunscreen?
No, this is a chemical sunscreen formulated with Mexoryl 400 and other organic UV filters. It absorbs UV rays instead of reflecting them, which is why it dries invisible with no white cast. Mineral formulas use zinc oxide or titanium dioxide and typically leave a white finish.
Can I wear this sunscreen under makeup every day?
Yes. The invisible fluid absorbs in seconds and leaves no greasy residue or white streaks. Apply it as the last step of your morning skincare, wait 60 seconds, then layer foundation or powder. The Netlock technology prevents pilling and keeps your SPF shield intact all day.
How is UVMUNE 400 different from regular SPF 50 sunscreens?
Most SPF 50 formulas block UVB and some UVA, but miss the ultra-long UVA wavelengths between 380-400nm. Mexoryl 400 captures those deep-penetrating rays that cause cellular DNA damage, photoaging, and stubborn dark spots. That broader coverage is what sets UVMUNE 400 apart.
Will this sunscreen sting my eyes if I sweat?
No. La Roche-Posay engineered this formula to be anti-eye-stinging, even during perspiration or water exposure. It was clinically tested on sensitive and reactive skin types. If you have a history of eye irritation from sunscreen, this fluid is a safer bet.

I was concerned about authenticity, so the first thing I did was to verify the lot number via a cosmetic verification website. Everything checked out and now I’m quite pleased to get this genuine Posay sunscreen for less.
Nice consistency
Fake. Counterfeit.
Hi Sara, thanks for reaching out and we’re sorry for the concern. This is 100% authentic La Roche-Posay, sourced directly in Paris. It’s the European version of UVMune 400, which has different packaging and a different texture than the versions sold in US stores, so it can look unfamiliar even though it’s the genuine product. We’d love to make this right. Please email us and we’ll share sourcing details or issue a full refund, whichever you’d prefer.
Clients Love Us
Finally found a US site that actually ships authentic French pharmacy products.
Order arrived in 4 days, perfectly packaged. Vichy Mineral 89 is the exact same formula I buy in Paris.
Had a question about Biafine and got a real reply the same day from someone who clearly knew the product. No chatbot nonsense.
I was skeptical about ordering skincare from overseas. Everything arrived tracked and perfect.
