The Ordinary Retinol 0.5% is Squalane is a water-free solution that contains 0.5% pure Retinol, an ingredient that can reduce the appearances of fine lines, of photo damage and of general skin ageing. While Retinol has been studied extensively, it is irritating to the skin and newer technologies exist that mimic the visible effects of Retinol without causing skin irritation. For this reason, we generally recommend using Granactive Retinoid 2% or Granactive Retinoid 5% instead of this formula.
All of our products are filled/measured by weight/volume so the product is correctly filled to 30ml. The packaging does not accurately reflect the size of the fill. However, this is intentional as some air must be allowed at the top for the product to actually close.
