Just recently I've started to notice I have lines around my mouth at all times, even when I'm not smiling. It's really bothering me, and it's making me embarrassed even. I know they are light, but I feel like they're more noticeable in person. They're worse after I smile, so it's making me want to keep a straight face at all times. I've tried a few things but nothing helps. Are there any suggestions that aren't extremely expensive?
