A high-active skin tightening serum for mature lines. Designed to reveal tighter, smoother skin and a reduction in surface lines and wrinkles. A sophisticated serum that mimics the smoothing and lifting effects of cosmetic-surgical line and wrinkle procedures through topical application. The potent SYN®-AKE peptide and supporting active ingredients work in tandem to tighten and smooth lines across the surface of the skin, instantly. Intelligent neurotransmitter-inhibiting peptides relax deep-lying micro-muscles to release, smooth and lift horizontal and lateral lines while supporting natural collagen synthesis, preventing further wrinkle formation. Bioplasma FA, a powerful phytoactive, enhances skin's detoxification capabilities, stimulating cellular metabolisms and reducing wrinkle depth. Antioxidants including Vitamin E and Resveratrol work to minimize the effects of oxidative stress and support cellular DNA repair, reducing signs of damage. AUTEUR's Hyaluronic Complex engineered with a range of micro-low to high molecular weights of hyaluronic acid, restores both long term and immediate hydration throughout all layers of the skin. Fragrance free. Made in Germany.
