SkinCeuticals A.G.E. Interrupter Ultra Serum is formulated to address structural skin ageing driven by collagen loss and glycation, processes that contribute to visible sagging, reduced firmness and the formation of wrinkles over time. This high-performance anti-ageing serum targets three key facial zones, working to improve definition across the forehead, cheeks and jawline for a more lifted appearance. The formula features 34.6% Flavo-Proxylane to help reinforce the skin’s support structure, improving firmness, elasticity and overall skin density. Rhamnose contributes to improved resilience and supports a firmer-looking complexion, while Gentiana Lutea Root Extract enhances the visible tightening and contouring effect. Clinical evaluation over 12 weeks demonstrated noticeable lifting across key facial areas, alongside improvements in smoothness and elasticity. The serum also provides up to 24-hour hydration and supports rapid strengthening of the skin barrier, leaving skin feeling firmer, smoother and more defined with continued use.
