Congratulations! You’ve graduated from the Retinol Night Cream No. 1. This means that your skin has happily adjusted to using retinol (without redness or irritation), and is ready to level-up. Retinol, also known as vitamin A, is the holy grail of performance skincare because it helps to soften, smooth, and brighten your skin while you sleep. This Retinol Night Cream No. 2 has .3% Retinol, which is double the concentration of our introductory Retinol Night Cream No.1. Why it Works: This nighttime cream has 2x as much retinol as our introductory Retinol Renewal Cream No. 1. We use encapsulated (slow release) retinol, a gentle form of retinol, to supercharge your results.
