A lot of people think they’ll see the results of their retinol use in 4 to 6 weeks, but this is not true. Most of the time, it takes a minimum of 12 weeks for you to start seeing positive results from your retinol use. You might also experience the “retinol uglies” before you see positive results. The retinol uglies don’t happen to everyone, but if they do happen, it’s usually for a couple weeks right after you start using retinol. This is the time when your skin adjusts to the new product, which might result in peeling, redness, and dryness. Don’t worry. If you stick with it, this adjustment period will give way to more luminescent and clearer skin.
