>>4340915>NTALook into how color grading works(primarily you'll find resources for the film industry such as the classic teal/orange or the mexico filter) and HSL adjustments(for example color blending of oranges/yellows/reds to get smoother skin tones).
In Lightroom you can do color grading on highlights, shadows, and midtones unlike with DxO Photolabs 7 where you can only do highlights and shadows which I dislike, however it's HSL handling is way better with better blending so it works out for either tool.
Midtones and HSL are where you'd be adjusting the most for skin color, and highlights for the type of lighting to work with or against the midtone, and the shadows for mood. You can also do masking for both if you want to color grade a specific thing.
You'll find digital will recreate blotchy skin tones exactly + that body's color science which can make it worse or better, where film is a lot more blended in that regard.
If you want some quick vids on demonstrating the basics and more in practice here's two:

Best thing to do besides watching youtube or getting advice from a mongolian plum picker forum is take some photos of yourself/friends/whatever and practice and learn by doing, read/watch and do it either by following along or adjusting things on the fly to see how they affect eachother.
Keep a color wheel up, disable and enable the grading//hsl adjustments a lot for checking, and have fun mang.
