Poderia ser Kingsman: The Golden Circle ?
Audiences believed Hart was a goner at the end of Kingsman: The Secret Service, but a flashback sequence in The Golden Circle reveals that two members of the U.S.-run Statesman agency swarmed onto the crime to investigate after Hart was left for dead. The American spies, played by Channing Tatum and Halle Berry, go into first-aid mode by wrapping a plastic-like shrink-wrap around Hart’s injured head.

When it’s activated, the shrink-wrap rapidly inflates with a swirl of orange and blue gel, which then fills in the hole in his skull. This “bio-foam” is what keeps [the victim] alive until nanites (nano-scale robots) rush in to repair the damage. It may seem like another ridiculous made-up tool in the super-spy toolkit, but its premise is something actual scientists have already considered.

FWIW, eu não vi o filme ainda. Eu me deparei com isso, fazendo uma pesquisa no Google por um gel de filme que cura um ferimento por arma de fogo.
