no difference - Review for Kiehl's Powerful-Strength Line-Reducing Concentrate - 1.7 oz.

i used this sample for a few months (i was only using it on one forehead line) but it made no difference as far as i can tell. i was using it once a day at night. im only 26 so its not like i was hoping for a miracle just a slight reduction in my only wrinkle lol.
