Upper lip still tight 13 months after sub nasal lip lift! What can I do to soften it?

Hi Doctors! It has been 13 months since my (skin only) sub nasal lip lift surgery. I had 8 mm removed mostly from center. I had a round of steroids at 6 months and micro needling recently, and all it did was increase stiffness under the nose down to the lip. I am self conscious to laugh or talk because it's still quite tight and I am having issues pronouncing certain letters. Is there anything I can do to soften things up at all? I hate this!
