I've heard so many people say that getting fillers at the corners of my mouth will make my philtrum look longer... But I think my mouth shape is a bit ㅅ-shaped, so I want to get fillers at the corners of my mouth ㅜㅜ I already got fillers for my lips, but can I just get fillers for the corners of my mouth separately?? I'm worried ㅠㅠ
