BIJOU DE MER Advanced Eight Serum

Beautè Invariante Advanced Eight Serum

(Renewed version launching November 2025)

From the cosmetic brand Bijou de Mer—which incorporates advanced marine microorganism ingredients and is known as “the treasures of the sea”—comes a special firming serum.

The serum is formulated with carefully selected cutting-edge beauty ingredients, including ocean-derived microbial extracts discovered through advanced bioscience. The product is designed to thoroughly address skin firmness and elasticity.

Serum could be used as lotion, serum, emulsion, eye care and targeted spot treatment for areas needing focused support. 

 It contains advanced firming ingredients sourced from around the world such as:

• Claribyne (Vitis Vinifera Callus Culture Extract)
• Sea HA+ (Bacillus Ferment, Hydrolyzed Hyaluronic Acid)
• Lacto Glaze (Lactobacillus Ferment, Caprylyl Glycol)

 Key oceanic firming actives include:

• Weewa (Alteromonas Ferment Extract), derived from microorganisms collected from the surface of jellyfish living near Cabrera Island in the Mediterranean.
• Mayview (Bacillus Ferment), sourced from extremophiles thriving in salt plants on the island of Mallorca, targeting hydration and firmness around the eyes.

Formerly known as “Beaute Invariante The Serum Essence G”, this formula has been renewed and further enhanced with high-performance beauty ingredients.
