I recommend a smudge-proof eyebrow product, even in summer.

I used it so much that one side is almost gone haha.

My favorite item is the Anna Sui eyebrow color.

The color isn't too intense, so it's not overwhelming.

The case is so cute, it makes it even better to carry around.

In the summer, eyebrow color often smudges due to sweat, but since this stays firmly in place, it doesn't, so I use it often during the summer.
