Expert Eyes Lash & Brow Serum

NATURALLY ENHANCED EYES
Expert Eyes Lash & Brow Serum
Biologique Recherche
Benefits

The Biologique Recherche Expert Eyes Lash and Brow Serum is an advanced double-serum treatment formulated to strengthen, nourish and densify eyelashes and eyebrows, delivering visible improvements in length and density within 14 to 28 days. Serum No. 1 is applied to the roots, Serum No. 2 through the lengths.

Serum No. 1 contains the Pea Extract and Sucrose Dilaurate Complex, which stimulates dermal papilla cells to support hair regrowth and reduce shedding, while also regulating melanin production at the follicle level for a more even-toned lash and brow line.

Resveratrol provides potent antioxidant protection against oxidative damage at the follicle, preserving follicle integrity and supporting denser, stronger growth, while Biomimetic Peptide and Red Clover Extract minimise hair loss by stabilising DHT levels and normalising hair growth cycles.

Serum No. 2 contains Abyssinian Oil — rich in omega fatty acids — which nourishes and reinforces the cuticle layer, reduces breakage and protects against environmental damage.

Rep'Hair (Vegetable Protein) penetrates deeply into weakened hair fibres to repair protein bonds, restore elasticity and strengthen from within — together delivering visibly fuller, longer and more resilient lashes and brows.

About the Brand
Brand logo
Founded in Paris in the late 1970s by biologist Yvan Allouche and physiotherapist Josette Allouche, Biologique Recherche began as a laboratory for bespoke, high-performance formulas for elite skin professionals. Their medical-grade precision and artisanal formulation, paired with consummate savoir-faire, underpin their reputation for outstanding, clinically proven results.

Biologique Recherche treats skin according to its Skin Instant©, the skin’s precise, evolving state. Each formula is loaded with active ingredients in exceptional concentrations, then prescribed to address those real-time needs. This precision approach corrects imbalances, restores function, and delivers visible, lasting transformation.

Cold-processed actives are the core of Biologique Recherche. Formulated at 18–25°C, this method avoids the 70°C heat of standard processing that breaks down actives. Botanical, marine, and biotechnological extracts stay intact for higher absorption, stronger repair, and better tolerance. Antioxidants, peptides, and enzymes remain stable, ensuring consistent, visible results.

Active Ingredients

  • - + Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)
  • - + Rep’Hair (Vegetable Protein)
  • - + Resveratrol (Eyelashes & Brows)
  • - + Biomimetic Peptide & Red Clover Extract
  • - + Abyssinian Oil (Eyelashes & Brows)
Pea Extract & Sucrose Dilaurate Complex (Eyelashes & Brows)

This advanced complex helps regulate melanin production at the follicle level by inhibiting PMEL-17 gene expression, which is involved in pigment formation. The result is a more even-toned, uniform appearance of the brow and lash line. Additionally, Pea Extract is rich in protein and stimulates dermal papilla cells, supporting hair regrowth and reducing shedding, ideal for promoting fuller lashes and brows.

Rep’Hair (Vegetable Protein)

Rep’Hair (Vegetable Protein) penetrates deeply into weakened hair fibers, delivering essential nutrients to repair and strengthen lashes and brows. Derived from hydrolysed vegetable protein, it moisturises and fortifies the cuticle, preventing damage and breakage. By enhancing resilience and promoting a smoother texture, it revitalises the appearance of lashes and brows for a naturally healthy, polished look.

Resveratrol (Eyelashes & Brows)

Resveratrol is a potent antioxidant naturally found in red grapes. When used on eyelashes and eyebrows, it helps neutralise free radicals caused by UV and environmental stressors, protecting the delicate hair follicles from oxidative damage. This protective action helps preserve follicle integrity, reduces inflammation at the root, and supports stronger, more resilient hair. Over time, it contributes to visibly denser, shinier lashes and brows by improving the health of the growth environment.

Biomimetic Peptide & Red Clover Extract

Biomimetic Peptide & Red Clover Extract help minimise hair loss by stabilising hormonal fluctuations, specifically in Dihydrotestosterone (DHT) levels, which are linked to hair loss. They also reduce scalp irritation and enhance cell renewal processes to normalise hair growth cycles, thereby reducing excessive hair loss and stimulating new hair growth.

Abyssinian Oil (Eyelashes & Brows)

Abyssinian Oil is rich in omega fatty acids, including erucic, oleic, and linoleic acids, which deeply nourish and protect eyebrow and eyelash hairs. It reinforces the cuticle layer, enhances moisture retention, and forms a lightweight barrier that defends against environmental aggressors and mechanical damage from makeup or styling. Known for its rapid absorption and non-greasy finish, it leaves hairs feeling soft and supple while reducing breakage. Its anti-inflammatory profile also helps soothe follicular irritation, encouraging healthier growth cycles and supporting hair density and shine.

Rep’Hair (Vegetable Protein)

Rep’Hair™ (Vegetable Protein) penetrates deeply into weakened hair fibres, delivering essential nutrients to repair and strengthen from within. Derived from hydrolysed vegetable protein, this biomimetic active is rich in amino acids that resemble the natural keratin structure of the hair, allowing for effective absorption and targeted action at the core of the fibre.

Once inside the cortex, Rep’Hair™ works to rebuild internal cohesion, reinforcing protein bonds compromised by chemical treatments, heat styling, or environmental stress. At the same time, it acts on the hair’s surface, moisturising and fortifying the cuticle—the outermost layer of the hair shaft—creating a flexible yet protective film that seals in hydration and reduces surface porosity.

The result is stronger, more resilient hair with visibly improved texture and shine. Split ends and breakage are reduced, elasticity is restored, and the hair feels smoother, softer, and easier to manage. Over time, hair regains its vitality, appearing naturally healthy, polished, and full of life.

Why I love it

  • The efficacy of Biologique Recherche relies not only on its science-driven approach to balancing and curing the skin, but on its prescriptive and tailored nature.
