Skin Tone Uniformity vs Photoshop

In reference to the Color Editor > Skin Tone tool, The Uniformity sliders move a range of colors around a certain point, towards that certain point. Be it hue, saturation, or lightness.

If you had to do what the Uniformity sliders of the Skin Tone tab do in Photoshop how would you do it?

It's easy enough to select one color and move hue, saturation, or lightness in either direction but I can't think of a way to bring a broader range of color towards a certain point, can you?
