1) When I get any hyaluronic fillers, my lips swell up in the morning. I am assuming because it attracts water from the tissue. Will this be an issue if I get fillers in the upper eyelid for hollow eyelids? 2) How long does filler in upper eyelids last? 3) Can the fillers be dissolved if I don't like it? 4) Which filler is best for eyelid hollowing due to previous revision double eyelid surgery?
