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.

Chemical Exfoliation

Chemical exfoliation uses acids to dissolve the "glue" holding dead skin cells together, promoting skin cell turnover and replacing old cells with new, healthy ones. Acids like AHAs, BHAs, and PHAs not only help shed skin but also offer benefits like brightening, clarifying, and anti-ageing, depending on the type used.

Brightening (Energising)

Energising 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.

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-PIH (Post-Inflammatory Pigmentation)

Anti-PIH treatments target Post-Inflammatory Hyperpigmentation (PIH), which shows up as dark marks after inflammation or injury, like acne. These skincare products help heal the skin, reduce inflammation, and promote regeneration while blocking melanin production. This helps fade and prevent dark marks effectively.

Complexion-Unifying (Anti-Blotchiness)

Evening skin tone is all about reducing blotchiness and achieving a more uniform complexion. Skincare products designed for this purpose use a blend of active ingredients, including soothing agents, anti-pigmentation compounds, antioxidants, and skin-restoring elements. These ingredients work together to diminish redness, inflammation, and pigment irregularities caused by inflammation, while also strengthening and protecting your skin against environmental irritants and future damage. This promotes healing and resilience, leaving your skin more balanced, radiant, and beautiful.

Pore Tightening & Minimising

Pore minimising involves reducing the appearance of enlarged pores. Enlarged pores often result from excess oil production and accumulated impurities, which stretch them over time. ageing also plays a role, as reduced skin elasticity makes pores more visible. Pore-minimising formulas tackle these issues by regulating oil production and boosting collagen and elastin to enhance skin elasticity. This helps pores return to their natural, less noticeable shape, giving your skin a smoother, more refined look.

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 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.

Regenerating

Regenerative benefits work to restore and renew your skin at a cellular level. By stimulating cell turnover and boosting collagen and elastin production, they help repair damage, diminish fine lines and wrinkles, and improve overall skin texture. The result is a rejuvenated, firmer, and more youthful complexion that radiates vitality.

Penetration Enhancing

Penetration enhancing in skincare involves advanced technologies designed to boost the absorption and effectiveness of active ingredients deep within your skin's layers. These enhancements ensure that skincare products deliver their powerful benefits precisely where they're needed most. By overcoming the common issue of low permeability in many effective ingredients, penetration enhancers maximise the unique benefits and visible results of your skincare routine.

Complex of Peach Tree Leaf, Apple & Raspberry Extracts

Complex of Peach Tree Leaf, Apple & Raspberry Extract also known as is rich in Vitamin C & Alpha Hydroxy Acids, combining anti-pigmentation activity with lightening and exfoliating actions, to combat sun and age pigmentation. The marriage of these ingredients not only results in a more even complexion where future pigmentation is reduced, but existing pigmentation is lightened.

Australian Finger Lime

Finger Lime Extract is naturally rich in Alpha Hydroxy Acids who's role is to exfoliate the superficial layers of the epidermis, resulting in a softer, brighter and more even complexion. This ingredient also contains vitamins, amino acids, minerals and antioxidants, which all work in conjunction with each other to support the natural health of the skin.

Dulse Extract

Dulse is a seaweed rich in Xylan's & Galactans, which work to reduce melanogenesis (pigmentation) by reducing the speed at which it can reproduce. The result is that it reduces photo induced pigmentation, creating a brighter complexion, a more even skin tone where age spots are diminished.

Alpha-Hydroxy Acids

Alpha-Hydroxy Acids are a chemical exfoliant which exfoliate the top layers of the skin, offering a variety of benefits. They are mostly derived from plant-based sources. Some of the most common AHAs are Glycolic Acid, Lactic Acid, Citric Acid, Mandelic Acid and Malic Acid. Depending on the type of AHA, they can reduce dullness, even skin tone, reduce pigmentation, tighten pores, stimulate collagen production, hydrate the skin and offer antioxidant protection. AHAs are generally less irritating and drying to the skin as they are water-soluble.

Poly-Hydroxy Acids

Poly-Hydroxy Acids are a chemical exfoliant which exfoliate the top layers of the skin. However unlike AHAs & BHAs, they consist of larger molecules so they tend to sit on the surface of the skin for longer and penetrate slowly. Therefore, they are particularly good for more sensitive skins. As well as sloughing off dead skin cells, revealing a smoother, clearer and brighter complexion; this acid is also a fantastic hydrator.

Magnesium Chloride

Magnesium Chloride contains astringent properties, but also promotes skin regeneration by increasing the amount of collagen and elastin fibres in the dermis.

Beta Hydroxy Acid

Beta Hydroxy Acid is a chemical exfoliant which penetrates deeply into pores to dissolve debris and dead skin cells. Because BHAs are oil-soluble, anti-bacterial & anti-inflammatory, they are particularly adept at treating active, inflamed and infected acne; even cystic acne. Also known as Salicylic Acid, this powerful ingredient is great at sebum-regulating the skin, reducing pores, lightening hyperpigmentation, fighting bacteria and easing inflammation.

Cider Vinegar

Cider Vinegar is extracted from fermented apples and contains high concentrations of fruits acids. Particularly potent in Acetic Acid, Citric Acid and Malic Acid; Cider Vinegar contains powerful exfoliating, purifying and renewing properties. High in Polyphenols, this ingredient also has significant antioxidant effects, combatting damageing photo-induced free-radicals.

Physical & Chemical Exfoliation

Physical and chemical exfoliation are two popular techniques for removing dead skin cells and promoting a healthier, more radiant complexion. Each method offers unique benefits and targets skin concerns differently, making them key components in any effective skincare routine. Exfoliation helps to improve skin texture, unclog pores, and enhance the absorption of skincare products, leading to smoother, brighter skin. Physical exfoliation offers immediate results, while chemical exfoliation promotes deeper, longer-lasting effects without the risk of physical irritation. Physical exfoliation involves the use of scrubs, brushes, or cloths with granules that manually slough off dead skin cells from the surface. This method provides instant smoothness but can sometimes cause micro-tears, making it less suitable for sensitive skin types. Chemical exfoliation, on the other hand, employs acids (like AHAs, BHAs) or enzymes to dissolve dead skin cells at a deeper level. This process promotes cell turnover, enhances the skin’s natural renewal process, and helps to reduce the appearance of fine lines, pigmentation, and dullness without abrasive action, making it gentler for sensitive skin. Physical exfoliation delivers a quick, refreshed feel, but those with sensitive skin might find it too abrasive. Chemical exfoliation gradually reveals smoother, brighter skin with regular use, and is generally better suited for those seeking a gentler approach with deeper results. Users often notice improved skin clarity, reduced congestion, and an overall glow. Both exfoliation methods have their place in a skincare routine, offering tailored solutions depending on skin type and needs. By choosing the right type of exfoliation, you can achieve a smoother, more radiant complexion that feels fresh, revitalised, and renewed, enhancing your overall skin health and appearance.
