The Ordinary Retinol 0.5% in 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.

The Ordinary’s portfolio of retinoids includes the following formulations:

Granactive Retinoid 2% in Squalane (Moderate Strength, No Irritation)
Granactive Retinoid 5% in Squalane (High Strength, No to Low Irritation)
Retinol 0.2% in Squalane (Low Strength, Moderate Irritation)
Retinol 0.5% in Squalane (Moderate Strength, High Irritation)
Retinol 1% in Squalane (High Strength, Very High Irritation)
