Bought this product yesterday looking for an actual product that may work well on dark spots. Unboxed, had no clue how to use. Went on Clarins site for directions and then started reading reviews. Thanks! I’ve been using Clarins for 30 years and never experienced such bad packaging. You don’t know what is in the bottle, dropper doesn’t work as proven by sales girl at return. Change packaging and maybe I’ll try it. Everything else I use is PHENOMENAL!
