Have your marketing strategy be posting the thirst trap photos your clients take once they are fully healed, with the caption "this thirst trap brought to you by dr.so-and-so." For starters, it now associates you with beautiful, sexy, happy, empowered, satisfied people, instead of an instagram grid of terrified before pictures.
If you don't know what a thirst trap is, congratulations on your happy marriage. To quote chatgpt: "A thirst trap is a seductive or flirty photo, video, or social media post intentionally designed to attract attention, romantic interest, or compliments."
It would be really easy for you to find a good boudoir or portrait photographer in your area to partner up with. After the client finishes with you, you send them to have a complimentary photoshoot. The photographer can coach the client through posing (hiding their face to obscure identity if requested / focusing on the area that was improved via surgery while not exposing too much. At the end, I'd recommend you ask the client to tell you which photo they like the best, and thats the one you post. Because thirst traps are all about what photos the poster felt sexiest in.
