I absolutely love this for summer because of its staying power. It is a little tricky at first to get the consistency of the brow powder and waterproofing gel mixed to perfection, but once its right, it is perfect! I usually use the powder on its own, unless it is a really hot day or I'm going swimming, then I will add the waterproofing gel. This is the first brow product I've ever used that stays ALL day and will not budge or sweat off. Because it is so pigmented, you have to be careful to only use a pinch of powder when mixing with the gel, or else it will be too dark. The only gripe I have is that there are only 2 shades available-Medium Brown (for light to dark hair) and Brunette (for dark to black hair...VERY dark.) On the plus side, you can alter the lightness-darkness of it by using less or more brow powder when mixing. This stayed on me and did not budge through a day of swimming (yes-underwater)! Would definitely buy again.
