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.

The Benefits

  • - + Anti-Redness
  • - + Anti-Inflammatory
  • - + Repairing
  • - + Soothing
Anti-Redness

Anti-Redness skincare is all about reducing and preventing facial or body redness, which can result from irritation, skin conditions, compromised barriers, and hormonal changes. A targeted approach with multiple strategies works best for tackling redness. Anti-Redness formulations include active ingredients that soothe and strengthen your skin barrier. Their anti-inflammatory and antioxidant properties calm inflammation and protect against environmental irritants. Additionally, these ingredients have vasoconstrictive properties, meaning they reduce blood vessel dilation to lessen redness. Together, these actions help achieve a more even-toned, balanced complexion that's less prone to redness flare-ups.

Anti-Inflammatory

Anti-Inflammatory skincare soothes, heal, and balance your skin, the targeted actives are designed to reduce inflammation. Inflammation is your body's natural response to injury or irritation, but continuous inflammation can lead to troublesome skin conditions like acne, rosacea, or eczema. Our anti-inflammatory skincare solutions work to soothe and calm your skin, reducing redness, swelling, and discomfort to provide much-needed relief. By strengthening your skin's barrier, these products help protect against further irritation and damage. Additionally, the anti-inflammatory actives support your skin's natural healing processes, leading to a more balanced and resilient complexion.

Repairing

Repairing your skin means restoring cells damaged by external factors like UV rays and free radicals, which can harm cell DNA and slow regeneration. Although our cells naturally repair themselves, this ability weakens over time due to ageing and repeated environmental exposure. Active ingredients can boost this natural process, preserving your skin's health, elasticity, and radiance. By supporting skin cell repair, these ingredients combat premature ageing and help maintain a firm, plump, and toned complexion.

Soothing

When your skin is sensitive or weakened due to genetics, skin conditions, using incorrect skincare products, or harsh weather, it needs extra care to repair and strengthening. Soothing ingredients with anti-inflammatory properties can reduce redness and irritation while strengthening the skin barrier, making it more resilient and protected against external aggressors.

Vitamin B3 (Niacinamide)

Vitamin B3 also known as Niacinamide, is versatile and highly effective ingredient with many benefits. It helps to strengthen skin barrier function and increase water retention by increasing natural ceramide production. It's anti-inflammatory and sebum regulating properties soothe, repair and balance irritated, weakened and acne prone skins. Niacinamide is also a potent antioxidant with protective and brightening properties helping to restore skin's natural glow.

Kudzu Extract

Kudzu Extract is a soothing active that quickly reduces inflammation and is particularly efficient at soothing skin conditions like rosacea. It works by limiting the action of phospholipase 2, an enzyme involved in inflammatory reactions. Kudzu extract also helps to improve the skin's resilience to irritation.

Red Microalgae Extract

Red Microalgae Extract is powerful ingredient fighting signs of rosacea and sensitivity. Its potent antioxidant and anti-inflammatory properties effectively reduce redness and sensitivity, while enhancing protection against environmental irritants and hydration.

Complex of Arnica Flowers, Solomon's Seal & Cypress Cones

The Complex of Arnica Flowers, Solomon's Seal & Cypress Cones has vasoconstrictive properties, meaning that it can reduce dilated vessels, and thus improve surface redness. They work in synergy to activate microcirculation which promotes better blood flow. This action reduces inflammation, strengthens capillaries, and aids skin healing.

White Tea Leaf Extract

Extracted from Camelia Sinensis buds, White Tea Leaf Extract is rich in antioxidants like catechins and polyphenols, protecting the skin from environmental damage and premature cellular ageing. Its anti-inflammatory properties soothe irritation and reduce redness, whilst promoting collagen production for enhanced firmness and elasticity.

Green Microalgae

Green Microalgae is a targeted active that reduces vascular imperfections by limiting the formation of new vessels and diminishing the appearance of existing ones. Its amino acid composition also stimulates collagen types I, III, IV, and VII, increasing density around blood vessels and reducing their visibility.

Understanding Rosacea

Rosacea is a chronic skin condition characterised by redness, visible blood vessels, and, in some cases, small, red bumps that can be mistaken for acne. Most commonly affecting the face, rosacea can be triggered by factors such as sun exposure, stress, spicy foods and alcohol. Managing rosacea involves gentle skincare products that calm inflammation and soothe irritation. Ingredients like niacinamide, azelaic acid and aloe vera can be effective, while harsh exfoliants and alcohol-based products should be avoided. Consistent sun protection is crucial to prevent flare-ups and further skin damage.

Clinical Proofs

Clinical Proofs

EFFICACITY TEST:
Study of the angiogenic activity on endothelial cells:
The proliferation and migration of endothelial cells are mechanisms responsible for the formation of
vessels. Their inhibition contributes to the reduction of the formation of vessels.
- Significant inhibition of -35.77% of endothelial cell proliferation after 24h of analysis
