* In collaboration with Clémence Besse, artisan perfumer, we have created a delicate olfactory signature, designed as a second skin. Light and subtle, this fragrance evokes the natural softness of the skin, through a subtle accord of soft musks, mimosa and tender woods. Allergen-free and synthetic fragrance-free, it respects the most sensitive skin while offering a unique sensory experience.

Yes, Le Fluide SPF50 was designed to replace your day cream. Its formula contains niacinamide and aloe vera, two active ingredients known for supporting the skin barrier and maintaining skin hydration. It delivers +117% hydration in 1 hour, making it a complete skincare product in its own right.

If you have very dry skin or more intense hydration needs, you can absolutely apply it over your usual cream. It fits perfectly into an existing routine, without feeling heavy.

Yes: skin prone to dark spots or melasma requires daily broad-spectrum protection, as exposure to UV rays and blue light is a known aggravating factor for hyperpigmentation. The Fluid specifically protects against both types of exposure. Dermatological advice is still recommended for personalized management of melasma.

Yes. The fluid has been formulated to be completely invisible on the skin, regardless of phototype.

Its fluid texture and new-generation UV filters provide a transparent finish, with no white residue. It can therefore be used on all skin tones, from very fair to the darkest skin.

This invisibility is particularly important for encouraging the daily application of sun protection, as white marks remain one of the main reasons why some people avoid protecting themselves.

No. The fluid has been designed to offer an invisible, lightweight, and comfortable finish.

Its texture melts quickly into the skin without leaving a white cast or a sticky feeling. The result is a natural, luminous finish that keeps the skin comfortable throughout the day.

Thanks to its lightweight texture, it can also be used as a makeup base, as it does not pill; it smooths and brightens the skin and makes applying foundation easier.

No more excuses for not applying your protection every morning!

This is the sun protection you will want to apply and reapply every day.

The skin is exposed to ultraviolet rays all year round, even when it is overcast or in winter.

UVA rays account for approximately 95% of the UV radiation that reaches the Earth's surface. Unlike UVB rays, which are responsible for sunburn, their intensity varies little with the seasons, and they can penetrate clouds and certain glass surfaces.

They penetrate deeper into the skin and contribute to skin aging, the breakdown of collagen, and the appearance of dark spots.

Wearing protection daily therefore helps to shield the skin from cumulative damage linked to daily exposure, even during simple activities like walking in the city, driving, or working near a window.

Prevention is key, which is why we have developed the fluid, the new essential for your beauty routine.

The fluid has a light, melting, and non-greasy texture that absorbs quickly without leaving a film. The classic sunscreen has a richer and denser texture.

Always apply the SPF50 fluid as the final step in your skincare routine, after your moisturizer and before makeup.

Apply 3 to 4 pumps every morning to the face, neck, and décolleté. Avoid the eye area.

The shelf life of the SPF50 Fluid after opening is 12 months. Store away from heat and light.

Ultraviolet rays are divided into two main categories that do not affect the skin in the same way.

UVB rays account for approximately 5% of the UV radiation that reaches the Earth. They act primarily on the surface of the skin and are responsible for sunburn.

UVA rays, which account for approximately 95% of UV radiation, penetrate deeper into the skin, reaching the dermis. They contribute to skin aging, the breakdown of collagen, and the appearance of dark spots.

UVA rays are also present all year round and can penetrate clouds and certain types of glass.

This is why it is important to use broad-spectrum protection capable of protecting against both UVA and UVB rays. Our fluid offers maximum protection: SPF50 for UVB and PA++++ for UVA.
