YouTube has a plethora of ways to create/correct skin color that all appear complex, needlessly so.
If you use a Mac, please translate to Mac specific instructions.

The process is simple:
Preparation:
► Find a skin color chart on the web or create your own. Note that the sample will need to have the same color depth as your image.
► Open your image, duplicate it.
► On the copy, create a selection around an area that is mid-range or close to what you believe is the person real skin color.
► Select surface averaging on the selection.
► Deselect the area.
►Click-drag your color chart from explorer onto your image.

Process
► Place/move the chart so that the closest color of the averaging sample is near identical.
► Use the color sampler tool and set a point on the selection chart. Make sure the sampler is set to 11*11
► Create a curve layer.
   → Select on the mid-point on the image below.
   → Using the info from the sample point, you create set the curve adjustment to the value as output per channel.

Clean-up
► Delete the chart and the image copy that has the averaging sample.

End of process
► Create a black mask.
   → Paint the skin area with white on the mask. (soft brush, adapt the size to the area)
► Adjust the change using opacity or blend if as needed.

You are done.

It is simple, anyone can do it.

Model:
Melanie, an 18 years old barista about to go to college to become a Soprano. The snapshot was taken with a cell phone (Google Pixel 7).

A resize was done using Upscayl. This is a stand-alone program, free. Upscaled x4 and then cropped.

The image I need for my final project...

I messed with the teeth, removed skin issues (other than color) and basically had fun doing that.

So why did I need a 'clean' image? I intend to create a scalable line art portrait of her. This is something I have never tried, so I go big in a way that my frustration grows and the more it grows, the more headstrong I became.

Wish me luck or a heart attack, depending on your point of view.
