Some people like to dampen their beauty blender before applying their makeup, as this can leave a smoother finish. If you dampen yours and it’s not expanding, it’s probably because it’s a knock-off beauty blender. The foam might not be as high-quality. It’s not a game-changer, though. Wash and use it as normal. Next time, if you want one that expands, opt for a different brand when you are replacing your current makeup sponge. We suggest Real Techniques — these sponges are highly rated with self-cleaning foam technology.
