La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50+ is a very high protection facial sunscreen with a weightless, water-light texture that disappears into the skin with no white cast. Built around the Mexoryl 400 filter, it defends against UVB, UVA, and ultra-long UVA rays up to 400nm, the deep-reaching wavelengths behind premature ageing and dark spots, while feeling invisible and non-greasy through hot, humid UAE days.

Why This Sunscreen Works

UVA rays reach deep into the skin, and the longest wavelengths near 400nm are the hardest to filter. Mexoryl 400 is a patented filter developed to cover this ultra-long UVA range, working within the XL-Protect filter system for broad-spectrum, photostable defence. Netlock technology anchors the filters in a resilient, invisible film, so protection stays put and resists water, sweat, and sand without stinging the eyes.

Ideal For

This invisible fluid suits all skin types across the UAE, including normal, combination, and sensitive or reactive skin, and anyone who dislikes the heavy, sticky feel of traditional sunscreen. Its weightless finish makes it easy to wear daily under makeup or on its own. If you specifically want a matte, oil-absorbing finish for very oily skin, the Anthelios UVMune 400 Oil Control Gel-Cream is the better match in the same range.

• Mexoryl 400: an exclusive UV filter that targets ultra-long UVA rays up to 400nm, reinforcing protection against sun-induced ageing and pigmentation.

• Netlock technology: locks a broad filter system into an invisible, non-greasy, non-sticky film for long-lasting, ultra-resistant wear.

• La Roche-Posay Thermal Spring Water: soothes and supports sensitive, reactive skin.

• Glycerin: a humectant that helps keep skin comfortable and hydrated under the SPF.

The non-perfumed formula is allergy tested, dermatologically and ophthalmologically tested, and suitable for sensitive skin and contact lens wearers.

1. Shake the bottle to mix the fluid, as the light texture can settle.

2. Apply generously to the face and neck as the final step of your morning routine, about 15 minutes before sun exposure.

3. Reapply every 2 hours and after sweating, swimming, or towel-drying.

The fluid is very light, so a few dots patted evenly across the face spread easily and layer well under makeup.
