Lip fat transfer reversal options?

I had a fat transfer where the surgeon put fat in my lower lip without my consent. He changed the shape of my bottom lip, making it bigger and more heart shape rather than bow shaped. He also bulked up my bottom lip. How do I remove this to go back to my natural shape and size? It’s been 6 months. I would like to know the most precise way to do so to get the best result, hopefully with minimal scarring. Thank you
