Last Saturday I hiked in 90-degree heat with my roommate. By the time we hit our post-hike latte spot, my go-to powder blush was a streaky mess halfway down my cheek. I’d borrowed the new YSL cream blush from my cousin who tests makeup for a living, so I touched it up in the bathroom. By the time we got home, that dewy flush was still perfect. No smudges, no fade. I ran the cost-benefit numbers: $46 is a splurge, but compared to the three drugstore blushes I’ve gone through this summer that melt in sweat? The math checks out. No logical gaps here. This one delivers.
