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.

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.

Anti-Bacterial

Anti-bacterial action targets and inhibits the growth of bacteria on your skin's surface. Anti-bacterial ingredients work by disrupting essential bacterial processes like cell wall synthesis or protein production, reducing the risk of skin infections and inflammation. They are especially effective for treating acne by controlling the acne-causing bacteria known as Cutibacterium acnes (C. acnes). This anti-bacterial action helps diminish imperfections, prevent new breakouts, and reduce irritation, giving you clearer, healthier skin.

Pore Decongesting

Pore decongesting focuses on both clearing and minimising the appearance of enlarged pores. Enlarged pores often result from excess oil production and the build-up of impurities within the pore, which can stretch them over time, while ageing further contributes as reduced elasticity makes them more visible. Effective formulations work first to clear the pores—dissolving and removing trapped sebum, debris, and congestion—before regulating oil production and supporting collagen and elastin to improve skin firmness. By addressing both internal build-up and structural integrity, pores can return to a clearer, more refined, and less noticeable state.

Purifying

Purifying skincare is designed to deeply cleanse and decongest the skin by targeting excess oil at its source—within the pores. Rather than simply removing surface shine, these formulations work to dissolve and dislodge sebum, debris, and impurities trapped inside the pore lining, helping to prevent congestion, blackheads, and breakouts. Actives such as exfoliating acids and oil-regulating ingredients penetrate into the pore to effectively “strip out” excess oil, restoring clarity and refining skin texture. By clearing buildup from within, purifying treatments leave the skin feeling exceptionally clean, balanced and visibly smoother.

Sebum Regulating (Mattifying)

Sebum regulation involves normalising oil production in your sebaceous glands to reduce shine, oiliness and breakouts, restoring your skin's natural balance. Overactive sebaceous glands can be triggered by internal factors like genetics, hormonal changes and stress, as well as external factors such as using stripping or overly active skincare, climate, pollution and diet. Excessive sebum production can lead to enlarged pores, acne and an oily, shiny appearance. Effective sebum regulation means using skincare products that balance oil levels without over-drying your skin, helping you achieve a clearer, more matte complexion.

Antioxidant

Antioxidant skincare is dedicated to protecting the skin against oxidative stress—one of the primary drivers of premature ageing and cellular damage—while preserving overall skin integrity and vitality. These formulations rely on potent molecules such as vitamin C, vitamin E, and polyphenols, which neutralize free radicals generated by UV exposure and environmental aggressors before they can compromise cellular structures like lipids, proteins, and DNA. Beyond defence, many antioxidants also support repair processes and enhance collagen stability, contributing to improved firmness, brightness and resilience. The result is skin that is not only shielded from ongoing damage but maintained in a healthier, more luminous state over time.

Anti-Pigmentation

Dealing with pigmentation means targeting melanin overproduction to reduce dark spots and prevent new ones. Melanin production can be triggered by UV exposure, pollution, hormonal changes (like during pregnancy), and inflammation (from acne or cuts). This excess pigment is then transferred to surrounding cells in epidermis called keratinocytes, which then moves to the skin's surface, causing visible dark spots.

To treat hyperpigmentation, a personalised and consistent approach is needed. Our anti-pigmentation products include lightening agents to block tyrosinase (the enzyme that creates melanin), antioxidants to fight free radicals, and ingredients to speed up skin cell turnover, removing pigmented cells. Using broad-spectrum sun protection is crucial to prevent new pigmentation during treatment.

Anti-Wrinkle

Anti-wrinkle skincare is focused on both preventing and visibly reducing the formation of lines by targeting the structural and dynamic causes of wrinkles within the skin. Fine lines and deeper wrinkles develop as collagen and elastin decline, cell turnover slows and repeated facial movements create creases that become etched over time. Advanced formulations address these mechanisms through a combination of elastin-stimulating actives, smoothing peptides that help relax the appearance of expression lines, and deeply hydrating ingredients that plump the skin from within. By reinforcing the skin’s architecture while softening surface contractions and improving elasticity, anti-wrinkle skincare delivers a visibly smoother complexion.

Firming & Lifting

Firming & Lifting skincare is designed to restore strength, structure, and definition to the skin, creating a visibly tighter, more sculpted appearance. As the skin loses collagen and elasticity over time, it can begin to soften and sag, losing its natural contours. Advanced formulations work to rebuild this support from within—boosting firmness while helping to visibly lift and redefine the skin. The result is a smoother, more toned complexion with enhanced bounce and resilience, where facial contours appear sharper and elevated.

Plumping

Plumping involves using active ingredients to boost the production of key structural components like collagen, the dermal-epidermal junction and glycosaminoglycans (GAGs), giving your skin more volume and density. Collagen provides structural support and firmness, while the dermal-epidermal junction, a thin connective layer, ensures smooth, wrinkle-free skin by facilitating cell communication. GAGs, like hyaluronic acid, keep your skin hydrated and plump from within. By stimulating these components, active ingredients help restore your skin's plumpness and radiance.

Renewing

Renewing skincare focuses on accelerating the skin’s natural turnover cycle to reveal fresher, more refined skin beneath the surface. At the core of this process are retinoids — vitamin A derivatives that function at a cellular level to regulate gene expression, increase cell turnover, and stimulate collagen production, leading to smoother texture, improved tone, and reduced appearance of fine lines and imperfections. Phyto-retinols, plant-derived alternatives, offer a complementary approach by mimicking many of these renewal signals while being generally better tolerated, helping to enhance skin regeneration and clarity without the same level of irritation. Together, these actives promote a continuous cycle of shedding and renewal, refining the skin’s surface while supporting long-term structural improvement for a visibly brighter, more even, and rejuvenated complexion.

Scar-Repairing

Anti-Scarring skincare targets the textured scars left by acne breakouts. These scars form due to inflammation disrupting collagen and elastin fibres leading to uneven healing and indented areas. Anti-Scarring actives harness growth factors and exfoliating actives to stimulate cell repair and regeneration, optimising the skin's healing process to reduce scar formation. They also effectively diminish older scars, improving overall skin texture and leaving you with a smoother complexion and significantly reduced scar visibility.

Brightening (Energising)

Brightening skincare involves using active ingredients to boost your blood circulation, detoxification and cellular energy. Improved blood circulation brings more essential nutrients and oxygen to your skin, while detoxification helps eliminate cell waste and impurities that can make your skin look dull. Certain active ingredients also enhance your skin's metabolism and regeneration. These combined actions restore your skin's vitality and radiant appearance, giving you a fresh, energised complexion.

Skin Barrier Strengthening

Strengthening your skin barrier involves replenishing the key elements in the top layer of your skin (stratum corneum), leading to a stronger and healthier barrier. These essential elements include lipids (ceramides, fatty acids, and cholesterol) and Natural Moisturizing Factors (amino acids, hyaluronic acid, etc.). Various factors, such as incorrect skincare use, seasonal changes, and aesthetic treatments, can damage your skin barrier. When this happens, your skin loses excess water through Trans Epidermal Water Loss (T.E.W.L) and becomes less capable of defending against environmental stressors, resulting in dryness, sensitivity, and irritation.

A healthy skin barrier is crucial for overall skin health as it helps prevent hydration loss, protects against environmental damage, and reduces the risk of skin conditions like eczema and acne. By strengthening your skin barrier, you ensure your skin remains well-hydrated, resilient, and protected.

Active & Inflamed Acne

Acne affects more than 640 million people worldwide, around 85% of whom are teenagers. The primary reason for dermatological consultation is classified into two main categories: inflammatory acne and comedonal acne. There are 3 levels of severity, depending on the number, type and distribution of lesions, as well as the presence of scars. Classification helps determine the most suitable treatment for each case. Comedonal acne is mild and non-inflammatory, consisting of black and white heads, while moderate to severe acne is inflammatory and consists of papules, pustules, nodules and cysts which can be sore to the touch and typically red or swollen in appearance. Acne is a complex, multifactorial, chronic disease involving genetic, metabolic and hormonal factors, with cutaneous and gut microbiota playing a key role.
