When searching for the Retinol formula for you, keep in mind that the percentage of Retinol in a serums is not all you need to pay attention to. It's important to note that Retinol serum with higher percentages don’t necessarily deliver the highest results, as the formula could be made up of combinations of Retinol and Retinol compounds as opposed to Pure Retinol.
Pure Retinol vs. Retinol Compounds
Instead of simply looking at percentages, you should also be mindful of the type of Retinol and other active ingredients within the formula as these will help ensure you’re able to incorporate a Retinol serum into your daily routine with minimal discomfort.
Pure Retinol is the most efficacious form of Retinol to look for as opposed to more mild forms such as Retinol compounds, but, especially for first-time Retinol users, higher percentages of Pure Retinol can also increase the likelihood of Retinol side effects including visible redness, dryness and peeling. At Kiehl’s, we’ve developed a serum with a technology that delivers a precise dosage of potent Pure Retinol for visible improvement in skin aging without the discomfort:
