I'd recommend using a waterproof Overtop and something thickening. But it works well and does what it's meant too. X would repurchase.
Reminds me of the Becca under eye brightener which I believe is discontinued. Using it when I work out instead of makeup with the mco skin tint. Great product.
Have been using for 2 weeks can definitely tell the difference with my eyebrows. Probably growing twice as fast as usual
