The Quintessential Serums are the core of the Biologique Recherche methodology: ultra-pure, cold-formulated serums that work at a molecular level to rebalance, repair, and strengthen the skin.
Each serum focuses on a specific function, hydrating, firming, clarifying, or revitalizing allowing true made-to-measure skincare.
They are formulated with high concentrations of amino acids, peptides, and botanical extracts to optimize skin function without artificial fragrances or fillers. Their minimalist composition means maximum efficacy and seamless layering. Results you see and feel.
Think of them as your routine’s “treatment architecture” , customizable boosters that you can mix, layer, or rotate depending on your skin’s needs.
Precision skincare at its finest.
