Add instant fullness to your brows in one step with this innovative, tinted filler that lasts all day! SmartBrow leverages a unique combination of polymers that bind color to your existing brows while also filling in gaps, creating a thicker, more defined look. Forget unnatural brow pencils or powders; SmartBrow creates natural-looking brows that will last all day -- even after swimming or showering. The innovative formula won't run, flake or transfer, but may be easily removed with the included cleanser. Plus, it features a dual-ended brush to ensure precise application and optimal shaping.
