Antioxidants

When it comes to antioxidant science, SkinCeuticals sets the gold standard. Each formula is backed by decades of research and built on the Duke Antioxidant Parameters — a precise combination of pure L-ascorbic acid (vitamin C), at an optimal concentration and a low pH for maximum skin absorption and efficacy. These potent antioxidants work deep within the skin to neutralise free radicals, defend against environmental aggressors, and support visible correction of fine lines, loss of firmness, and dullness. The result: stronger, brighter, more resilient skin — protected where it matters most.
