I recommend the Make Up For Ever UHD Pressed Powder.

My eyeliner tends to smudge easily when I do my makeup, so I was looking for a way to make it smudge a little less. I found information saying that if you apply a little powder before applying eye makeup, it smudges less.

So, I immediately bought the famous Make Up For Ever powder and gave it a try, and I could definitely see a difference in how much it smudged when I used it compared to when I didn't. Since then, whenever I want long-lasting makeup, especially during the hot summer, I tend to apply powder even though it's a hassle. If you are struggling with your eyeliner smudging, I recommend trying the powder method.
