I think aloe soothing gel is the best for cooling down facial heat.

You know how your face gets all flushed when you come home from going out after the weather gets hot? ㅠㅠ When that happens, if you apply a thick layer of chilled aloe soothing gel like a mask, the calming effect is seriously amazing! It costs less than 10,000 won, so you can use it generously without worrying about the cost. It absorbs without any stickiness, so I've lost count of how many jars I've emptied and bought already! If you have redness or a lot of heat in your face, you absolutely must stock this on your vanity!
