What was your experience with Ren aha concentrate? what about Ren radiance serumwhat makes one different from the other? Which one is stronger? also which one is better for acne marks?
I tried RENs glycolic peel and the serum...they are ok. The peel is good but I haven't been impressed with the serum at all. I recently tried the Exolikate and I noticed a HUGE difference in smoothness of skin. If I could return my REN stuff for the exolifkate I would in a heart beat.
