Review title is Updated review - not waterproof [SEP] Updated review: This Eyebrow Tattoo Pen in light brown is a good color for light blondes!  The formula advertises to be sweat proof/waterproof, but that is definitely not the case. I wore this and sweated when I wrote my initial review, but after getting wet in the rain, this product seemed to disappear (my reason for removing a star). It has a natural look to it with a 4-fork tip head that lets you create more realistic looking brows. This gets 3 stars for its wearability and durability and application. The formula goes on quite dry so you really have to work in applying yet so it looks even on both brows. However, I like the color and the fork applicator. See my pictures for a before and after (First picture is before and second picture is after application of this product).
