픽서는 써볼 생각을 안해봤는데 저도 여름에는 인중까지 땀이 나서 궁금하네요.
I started using this setting spray because sweat tends to bead up easily on my nose and philtrum during the summer. I used to avoid using it because I was worried my makeup might smudge or wear off, but I finally gave it a try because it kept smudging on hot days. Well, in conclusion, it was fine for me. It feels slightly moisturizing when you first spray it, but once it dries, it adheres well, so even when I sweat, the makeup around my nose and philtrum didn't break down as much as usual. However, you need to be careful with the amount and distance you apply so it doesn't run down. The scent is also subtly pleasant, and if you tend to wear slightly thicker makeup, I think it's worth trying at least once during the summer. However...
If you prefer natural makeup or touch your face often, don't bother using this; it can clump if you're not careful.
Anyway, if you use it well, it's a great item to use in the summer.
