Serum Vivant
Benefits
Launching mid-January. Join the waitlist below.
Sérum Vivant by Biologique Recherche is a lightweight corrective serum designed to reduce persistent blemishes, regulate excess sebum and calm associated redness without drying the skin. Developed for oily, combination and blemish-prone skin, its slightly gelled, aqueous texture absorbs quickly, leaving a comfortable, non-greasy finish.
Signature Yeast Extract works alongside prebiotic Inulin to support the skin’s microbial balance. Inulin selectively nourishes beneficial microorganisms naturally present on the skin’s surface, whilst Yeast Extract contributes to the formula’s postbiotic approach, supporting barrier function and skin comfort.
Lentil Seed Extract and Mastic Gum target excess shine and enlarged pores, promoting smoother, more refined skin texture. Rose Myrtle Fruit Extract complements this purifying action, targeting blemishes and soothing associated redness.
Bacillus Ferment provides additional skin-conditioning support, whilst Polylysine contributes antimicrobial activity. Phytic Acid binds metal ions that can accelerate oxidation, supporting the formula’s antioxidant protection.
The result is clearer, calmer and more balanced skin, with fewer persistent blemishes, reduced shine and a smoother, more refined complexion.

Active ingredients
Yeast ExtractMicrobiome Balancing · Brightening · Sebum Regulating
Yeast extract is a bio-fermented active that helps rebalance the skin’s microbiome while regulating excess sebum and reducing congestion or dullness. By supporting a healthier microbial environment, it limits the growth of unwanted bacteria on the skin’s surface, helping to purify and refine texture without stripping or irritation. Its enzymatic action also encourages gentle cellular turnover, which helps lift away built-up dead skin cells and improves clarity, contributing to a brighter and more even complexion. Furthermore, yeast helps to reinforce barrier function so the skin remains more stable, resilient, and less reactive over time. This makes yeast extract especially effective for skin that is unbalanced, oily-tendency, stressed by urban pollution, or in need of both soothing repair and a clearer, healthier surface environment.InulinMicrobiome Balancing
Inulin is a prebiotic polysaccharide that selectively nourishes beneficial microorganisms naturally present on the skin’s surface. By supporting microbial diversity and maintaining a balanced skin microbiome, Inulin reinforces barrier function and promotes lasting skin comfort.Lentil Seed ExtractSebum Regulating · Pore Decongesting
Lentil Seed Extract contains natural oligosaccharides that regulate excess sebum and support healthy keratinisation, reducing the build-up of dead skin cells that can congest pores. It also refines enlarged pores, smooths skin texture, and reduces excess shine.Rose Myrtle Fruit ExtractAnti-Bacterial · Antioxidant · Anti-Inflammatory
Rose Myrtle Fruit Extract contains natural antimicrobial and antioxidant compounds that target blemish-causing bacteria and protect against oxidative stress. It also soothes inflammation and reduces blemish-related redness, promoting clearer, calmer skin.Mastic GumBrightening · Pore Decongesting · Antioxidant
Mastic Gum is naturally rich in antioxidants and anti-inflammatory agents. It effectively fights signs of photo-ageing, enhances skin clarity and radiance, and reduces the appearance of enlarged pores.Bacillus FermentMicrobiome Balancing · Anti-Bacterial
Bacillus Ferment is a probiotic derived from fermenting the bacterium Bacillus subtilis. This ingredient supports the skin's microbiome by fostering the growth of beneficial bacteria, enhancing the skin's resilience against environmental stressors. Additionally, Bacillus Ferment possesses antimicrobial properties, helping to control the overgrowth of harmful bacteria and promoting a healthy, balanced complexion.PolylysineAnti-Bacterial
Polylysine is an amino acid polymer with antimicrobial properties that inhibit the growth of certain bacteria. It contributes to formula preservation and supports the targeted action of skincare developed for blemish-prone skin.Phytic AcidBrightening · Sebum Regulating · Pore Decongesting
