I've tried the original Cosrx acne pads before and they work well in terms of calming the skin with breakouts. But it is definitely not as hydrating at these ones. They have a citrusy scent to it that's really nice. If you're sensitive to smells, I'd avoid this. It leaves the skin with a nice hydrating layer and you can sometimes use it as an express hydrating cheek patch. Absolutely love it and this set comes with stickers too. Super cute.
