What is retinization?

Retinization is the adjustment period in which the skin becomes acclimated to a retinoid. During this time, skin may become irritated, resulting in dryness, scaling, redness and burning/stinging. These symptoms usually peak at the two-to four-week mark before subsiding but they can happen at any time depending on your skin’s sensitivity. Not everyone will experience these side effects and in clinical studies, average side effects were less than mild. Using a non-medicated moisturizer can help relieve the dryness associated with retinization.
