I have these weird lines near my mouth and I'm only 18 so it's not really like wrinkles but more like really dark lines and they're kinda hollow. I feel like I need to add cheek fat or something? And yes, I've tried skincare for like 2 years vitnam c, retinol and other serums and although it has gotten a lot better it still always gonna be there unless I can help with plastic surgery but I'm not sure. Please someone let me know what I can do, thanks!!
