  • Anti-Inflammatory
  • Hydrating
  • Anti-Wrinkle
  • Plumping
  • Brightening

The Biologique Recherche Lait Dermo-S is a soothing cleansing milk specifically formulated for sensitive, reactive and rosacea-prone skin. Combining neuro-soothing actives with barrier-strengthening botanicals, it cleanses effectively without triggering redness, stinging or discomfort.

Coconut Derived Esters — the lead cleansing active — dissolve lipophilic impurities and remove buildup thoroughly without stripping the skin's lipid barrier. Red Sage Root Extract is a neuro-soothing active that inhibits TRPV1 receptors — the nerve channels responsible for the burning, stinging and itching sensations common in sensitive skin — significantly reducing inflammatory response and restoring comfort.

Panthenol (Pro-Vitamin B5) hydrates and supports skin regeneration, Prickly Pear Cactus Extract soothes, nourishes and reinforces the skin's protective barrier, and Vitamin B3 (Niacinamide) strengthens barrier integrity, reduces redness and calms inflammation — leaving the skin clean, soft and visibly calmer.

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.

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.

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.

Hydrating

Hydration is a fundamental part of healthy skincare, focusing on maintaining and restoring the skin’s water content. Well-hydrated skin appears plump, smooth and radiant, while dehydration can lead to dullness, tightness, fine lines and increased sensitivity.
Hydrating the skin can work through a fascinating mix of ingredients with different roles. Humectants like hyaluronic acid and glycerin act like water magnets, pulling water into the skin to instantly plump and smooth, while Natural Moisturizing Factors (NMFs)—such as urea, amino acids and sodium PCA—mimic the skin’s own hydration system, helping it hold onto water and stay balanced from within.
Adding humectants like hyaluronic acid to your routine will restore your skin's healthy glow, minimize fine lines, and provide a plumping effect.

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.

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.

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.

Coconut Derived Esters

Coconut Derived Esters solubilises lipophilic dirt (dirt attracted to oils) and removes impurities for a very effective cleanse without stripping the skin and disturbing the skin barrier function.

Red Sage Root Extract

Extracted from Salvia Miltiorrhiza, a resilient medicinal herb, Red Sage Root is a multifunctional active that targets the three key causes of skin sensitivity: inflammation, barrier damage, and neuronal hyperreactivity. It calms the skin by inhibiting TRPV1 receptors, restores barrier integrity, and reduces redness. Rarely used in conventional formulations, it delivers clinically proven soothing and strengthening effects for fragile skin.

Panthenol (Pro-Vitamin B5)

Panthenol, also known as Pro-vitamin B5, is a potent humectant renowned for its exceptional hydrating, repairing, and soothing qualities. When applied to the skin, Panthenol converts to Coenzyme A, an enzyme crucial for skin regeneration. Its versatile benefits and compatibility with all skin types make Panthenol a preferred choice for replenishing and fortifying dehydrated and compromised skin.

Prickly Pear Cactus Extract

Prickly Pear Cactus Extract has strong water retention capabilities which have powerful nourishing benefits and therefore are extremely effective at combatting dry skin. Moreover, its piscidic acid content is adept at protecting the skin from oxidative stress, preventing premature cutaneous ageing. Lastly, it contains soothing benefits as it blocks stress markers in the skins' sensory nerve cells, which calms the skin.

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.

Red Sage Root Extract

Red Sage Root Extract, derived from Salvia Miltiorrhiza: a revered medicinal herb in Traditional Chinese Medicine, is a next-generation active that targets the root causes of sensitive skin. Clinically proven to calm, protect, and restore, it acts on three key biological fronts: inflammation, barrier dysfunction, and neuronal hyperreactivity.

It works by inhibiting TRPV1 receptors, which are responsible for sensations of burning, stinging, and itching. By calming these pathways, Red Sage Root helps to desensitise reactive skin and reduce flare-ups. Simultaneously, it strengthens the skin’s protective barrier, reduces trans epidermal water loss (TEWL), and improves overall resilience to external stressors like pollution and temperature shifts.

Beyond its neuro-soothing benefits, Red Sage Root delivers powerful anti-inflammatory and antioxidant activity, reducing visible redness and reinforcing the skin’s defences over time. It also helps regulate the skin’s immune response, minimising chronic inflammation that can accelerate ageing and sensitivity.

While its complex biochemical profile has historically limited its use in mainstream skincare, advanced formulation techniques now allow for its full potential to be harnessed. The result is a transformative ingredient that not only soothes on contact but helps condition the skin long-term, promoting a stronger, calmer, and more balanced complexion.
