Biologique Recherche Serum Colostrum VG is a deeply nourishing serum that strengthens the skin barrier, reduces dryness and prevents water loss. It replenishes the skin's protective lipid film, leaving it softer, soothed and well nourished. Water Plantain Extract is rich in peptides and acts similarly to probiotics, strengthening the skin's natural immune system and reinforcing the skin's barrier function to allow the retention of hydration. It creates an ideal, calmed environment in which the skin's repair and renewal processes can function optimally. Luffa Oil — with a natural composition of 72% polyunsaturated fatty acids close to that of the body's own lipids — restores the normal lipidic state of dry skins and rebuilds enough oils to replenish optimal barrier function. Together, these two actives restore comfort, nourishment and vitality to compromised or devitalised skin, progressively improving its texture, smoothness and overall healthy appearance with regular use.
