Retinol 0.5% in Squalane

This highly stable, water-free, high strength age-defying solution features 0.5% pure retinol. This special form of vitamin A has been proven to minimise fine lines, improve pigment problems, revitalise skin and make its overall appearance fresher and more youthful. As retinol can cause irritation, The Ordinary recommends beginning your regimen with lower concentrations (such as {Retinol 0.2% in Squalane}) to allow skin to build up tolerance.
