The Ordinary Retinol 0.5% in Squalane

This water-free solution contains 0.5% pure Retinol, an ingredient that can reduce the appearances of fine lines, of photo damage and of general skin aging. 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 Gran-active Retinoid 2% or Gran-active Retinoid 5% instead of this formula.

Caution:

Retinol can cause significant irritation, redness and peeling, especially around the eyes and mouth, in the early stages of treatment while skin builds tolerance.
