"Retinol-mirroring results, made suitable for sensitive skin. This clinically proven healthy ageing serum combines Ren's plant-derived alternative to Retinol, Bidens Pilosa, with Ceramides and Niacinamide to firm, even tone and pigmentation, plump, smooth, and improve elasticity, while visibly reducing fine lines and wrinkles after just 7 days. Added Niacinamide, a multi-active stable form of Vitamin B3, helps protect against free radical damage and improve brightness and firmness; while Ceramides from Wheatgerm work to strengthen the skin barrier, increase skin hydration, soothe and reduce irritation."
