This is a Line ERASER, the @Kiehl's Since 1851 Powerful Strength Line-Reducing Concentrate, it faded the fine lines under my eyes so much. It is extremely potent (you’ll feel it) so start with just a little bit. I suggest using it at nighttime after cleansing before moisturizer (or with, if you have sensitive skin). But WOW I 10000000000% recommend. #vitaminc #skincare #antiaging #kiehls
