Some comments from one who does tend to oversaturate things.
Calibrate Monitor for colour and brightness. Numerous hardware and software options are available for this.
Use an IPS monitor for colour accuracy and better viewing angles.
Operate in a slightly darkened room
I use Lightroom almost exclusively so these remaining comments relate to that program but my also apply to other applications.
- Crop, clone and level
- Adjust overall exposure if necessary
- Adjust white balance only if necessary
- Adjust overall contrast only if necessary
- Set White point
- Set Black point
- Adjust image overall brightness Note: for this and the above two steps, I follow a technique of dropping the Highlights slider to -100, boosting the Shadows slider to +100 and then setting the white and black points.
- Go easy on Texture and Clarity controls.
- Adjust Vibrance in preference to saturation slider especially with skin tones.
- Go easy on Saturation. Use this sparingly.
- Use local edits, Graduated Filter, Radial Filter and Brush to correct problem areas.
- Keep an eye on the overall image as you do any of these steps. It is easy to get carried away on one particular area.
- Noise and sharpen
Most important, walk away from the image for at least 1/2 hour, preferably overnight and look at it again with fresh eyes.
There are a great number of You tube videos with details of these techniques. Chose some presenters you like and follow their examples.
Good luck
