Looks a lot like a photomanipulation or AI slop touchup.
It just looks like 3D models for me. I see no telltale signs of AI, like stretched textures as a result of pixels being moved around. The area around the mouths in particular shows some stretching of the texture, but it looks like stretching because of deformation of the underlying 3D mesh. Overall, while the texturing here is quite realistic, real skin is still more complex than this. Also, look at the hair, it does not look all smooth as you'd expect from real hair strands. The only thing in this render that's almost-real is the lighting, because it's imitating the flash of a camera, that might be what's tripping you up.
