I used to blame my foundation for makeup breakdown. Turns out, the real issue was my setting spray. Here’s what changed everything: - Some setting sprays lock makeup in place (https://qualityhow.com/best-setting-sprays-for-makeup-durability/); others just remove powdery finish - Humidity resistance is completely different from oil control - Alcohol-heavy sprays can make makeup crack faster - Skin type changes which spray actually works Once I started matching setting sprays to conditions instead of hype, my makeup lasted significantly longer, even in heat.
