I use an over the counter Retinol product (Roc), and I do use the Pevonia on the same nights I use the Retinol. Only difference is, I put about 10 minutes between applications. I use the Retinol on my freshly washed face, wait 10 min, then use the Pevonia. No problems, and I have very sensitive skin!
