Well with the raw histogram you can evaluate exactly the extent of the raw clipping, which is good for honing your exposures later.
But the key is a highlight color inpainting algorithm borrowed from RawTherapee that reconstructs color channels based on the unclipped channels. On skin you get very smooth gradients at the edge of clipped areas and the highlight reconstruction is particularly free of artifacts.
But that needs to be brought into a reasonable brightness range for output. The tone mapping from the film simulation works well on skin to preserve color when darkening highlights.
That particular photo has both the blue and green color channels clipped, but the red channel let Filmulator reconstruct plausible data flawlessly. Here's the raw histogram from that file: https://i.imgur.com/NLZeM5h.png
