Ugh, keep me far from that makeup! It doesn't come with a computer program.
I’ve been a heavy Photoshop user for twenty years, and I don’t see any telltale signs that the image has been manipulated. No inexplicable soft spots, there are areas that would have been improved, if someone were to have been idealizing the image, especially the neck.
That’s just very skillfully applied makeup, imho. Favorable lighting, too.
