Biologique Recherche Serum Iso-Placenta is a healing and regenerating serum that strengthens and rebuilds the skin. Ideal for post-acne scarring and post-peels, it enhances cell regeneration, reduces blemishes and redness, and lightens pigment spots. Biomimetic Placenta contains key growth factors similar to those in the human placenta, aiding in cell growth and skin regeneration while helping to heal and reduce post-acne hyperpigmentation and scarring. It is one of the most powerful regenerating actives in the Biologique Recherche range, boosting collagen and elastin production and producing measurable improvements in skin vitality, texture and overall quality. Carob Seed Extract triggers the recovery and reparation of skin tissue, accelerating epidermal and dermal reconstruction through the production of myofibroblasts and growth factors. Scotch Thistle Extract stimulates skin thickening and keratinocyte differentiation, promoting skin reparation and collagen synthesis for a firmer and stronger skin structure, resulting in skin that is visibly more vital, smoother, more luminous and thoroughly renewed with regular use.
