Bioderma Sensibio AR+ Bi-Serum is an advanced dual-action treatment specifically formulated for sensitive, reactive skin prone to redness and signs of aging. This innovative bi-phasic serum leverages ROSACTIV™ 2.0 technology to target the biological sources of redness, providing both immediate soothing relief and long-term reduction in visible flushing. Enriched with Bakuchiol, a plant-based alternative to retinol, it effectively stimulates collagen production to firm the skin and diminish the appearance of fine lines and wrinkles. The formula is fortified with D.A.F.™ technology to bolster the skin's natural resilience. Its lightweight, non-greasy texture absorbs quickly, delivering 24-hour hydration and leaving the complexion calm, smooth, and even.
