홍삼장군님
우와 입술에도 발라줘야 하군요 몰랐어요
It is the lips.
I heard that you must apply sunscreen to the lips because they are the thinnest and most delicate part of the skin and lack melanin pigment.
I hear that you should apply sunscreen, or if you don't like that, use lipstick or lip balm with UV protection.
I haven't been applying sunscreen to my lips either, but I should start now.
