A powerful dual-phase formula designed to visibly smooth 100% of wrinkle types (smile lines, forehead lines, crow’s feet), tighten pores from the very first use, and leave skin texture 2X finer, without irritation, even for sensitive skin. After using the bi-serum, 9 out of 10 people have had their pores refined, 8 out of 10 people have younger-looking skin and have their deep wrinkles appear filled and 92% of people have their skin transformed being softer and smoother.* At the heart of the formula, two retinol-like active ingredients of 100% natural origin work synergistically within the exclusive [RE]NEW technology to reactivate skin renewal at both the dermal and epidermal level. An encapsulated biomimetic microalgae derived from biotechnology delivers a structural analogue of retinoic acid, stimulates cellular activity and targets fibroblasts, outperforming retinol, while an active fraction from mastic tree, which is plant-derived, protects and enhances retinoid mechanisms. It inhibits retinoic acid degradation and increases gene expression involved in the retinoid cascade. Formulated with 99.8% ingredients of natural origin, this lightweight serum absorbs quickly and delivers visible results with lasting comfort. 30ml *Tested under dermatological control – Twice-daily application on 24 women – 46 to 70 years old – all skin types including sensitive skin – Wrinkles: Significant self-assessment results on 100% of the wrinkle types evaluated at Day 56.
