"After using both brands side by side, the differences become more obvious than the scores suggest. To be honest, it wasn’t immediately clear which one I’d prefer. Honestly, scores only tell half the story. In our testing, COSRX felt surprisingly intuitive day-to-day, even if it had a few quirks."
"Then I switched back to NYX Series 5. While it's consistent, it lacks a bit of that 'heart.' It's a very solid choice, but COSRX is where the actual comfort is for me. If you're also comparing flagship devices, you might want to check our full Beauty comparison guide."
