Are there any people whose upper lip rolls in and becomes thin when they smile? ㅠㅠ When I'm still, my lips are average thickness, but when I smile, my upper lip disappears completely..ㅠㅠ I didn't think much of it, but when I look at my recent photos, I feel a bit stressed, so I wonder if it would look better if I got some filler in my upper lip? ㅠㅠ
