The Alyria skin optimizing system is available exclusively through physicians. Breakthroughs in scientific research and state of the art technology make Alyria one of the most comprehensive and sophisticated skincare lines available. Matrixyl, a pentapeptide is the active ingredient in the Alyria anti-aging products. It mimics the skinís natural regenerative process, stimulating collagen synthesis. This in turn promotes tissue repair and effectively diminishes fine lines and wrinkles. Matrixyl is compatible with most sensitive skin types and because it is a protein, it gives the added benefit of being a great humectant, helping skin to lock in moisture.
