I recommend the Avène Cold Cream Nourishing Lip Balm from Olive Young, which I bought with my own money!

Avène lip balm is famous, right? It comes in a convenient 4g size, and it's currently on sale at Olive Young for 12,700 won (originally 15,000 won). Thanks to the shea butter ingredient, it's a highly moisturizing lip balm that is said to last for 6 hours. It has undergone skin sensitivity testing, so it's safe for the whole family to choose!! I'm even more satisfied with its melting texture. I highly recommend it.
