Hi Folks, I recently moved from Retinol 0.5% to Retinol 1.0%. I believe the next step above Retinol 1.0%, is Retin-A. Two questions: 1. What should I strive to obtain/purchase now that I am looking for something stronger than Retinol 1.0% 2. Lastly, my skin experiences peeling with both Retinol 0.5% and 1.0%, however, eventually handled it very well. Now that my skin handles Retinol 1.0%, should I assume it can handle Retin-A, or should I plan for some the same grace period while it adapts?
