Biologique Recherche Serum Matriciel is an anti-ageing serum for the body. It intensely tones, plumps and improves the skin's elasticity for firmer, more hydrated, smoother and more luminous body skin. A Complex based on Elderflower, Chestnut Wood & Myrobalan Leaf Extract is ultra-rich in polyphenols and flavonoids, providing strong antioxidant properties, boosting microcirculation and toning and firming ageing body skin. The Glycoprotein of the Antarctic Microorganisms prevents skin from drying, boosts collagen and elastin production and helps keep the skin smooth and resilient. Horsetail — rich in actives that stimulate collagen, elastin and glycosaminoglycans including hyaluronic acid — directly supports the skin's firmness, tone and hydration. Rye Extract stimulates fibroblast activity, while Marine Exopolysaccharide and NMF restore hydration and barrier function, producing body skin that is progressively firmer, smoother and more densely nourished with regular use.
