This serum intensely hydrates the skin, and repairs the skin's outer barrier – vital for locking moisture in. Hyaluronic acid helps the skin retain moisture, giving it a healthier, plumper and more youthful appearance. Ceramides are made up of long-chain fatty acids that create a barrier to prevent moisture loss, helping prevent dryness and irritation. Another star ingredient in this formula is ectoine, an amino acid that boosts the skin's hydration levels and elasticity, and stenghtens the skin's barrier. Finally, madecassoside, which is derived from the leaves of the centella asiatica (or 'cica') plant, helps reduce inflammation and redness, and stimulates collagen production, firming the skin and reducing the appearance of fine lines and wrinkles.
