What it does

  • Supports natural collagen production, so skin feels firmer over time.
  • Works on the visible signs of ageing — fine lines and loss of firmness.
  • Optimises texture, smoothness and the way skin reflects light.
  • Supports the barrier rather than taxing it — tolerated by sensitive skin.
