How can I fix the dark lines that curve down from my lips? I am willing to try anything it's a huge insecurity. (Photo)

I used to think it was hyper pigmentation from eczema when i was younger but after years of bleaching creams like tri-luma and meladerm as well as microdermabrasion I realised that the lines slightly indent inwards like minor marionette lines. I really hate them. Would juvederm work?
