Does video quality deteriorate with multiple edits?

I made a video today but I overexposed in camera. Using PD15 I have tried to correct the exposure by a series of tests.
Using fix/enhance I have tried reducing Exposure, then Brightness, then Lighting. note of these produced a satisfatory H265 MP4 movie.
The biggest problem was that as I made the test series all from the original saved project the colour changed to make skin unnatural and blotchy.
Apart from that I'm wondering if the timeline clips deteriorate after each test just like JPG images do with multiple edits?

Only if you bring the "Produced" video back into the timeline, perform additional edits, produce and repeat steps. When full encoding is done again and again, yes it does loose some quality each pass, especially with lower end bitrate source.

Multiple adjustment edits applied to a clip in timeline and "Produced" is better quality than doing the same in a loop fashion of applying one adjustment edit, produce, use that clip in the timeline to apply another total clip adjustment, produce,.....

Jeff,
thanks for your reply. I did the first Produce then leaving this project file open I returned to the editor made the edit then produced again and repeated for each adjustment . So I guess this is okay and would not result in video deterioration as presumably all but the last production are overwritten or deleted?
When I bought PD Ultimate it included ColorDirector but I had to purchase a further download after changing my computer. When I did this Color Director did not get downloaded even although it is listed in my Director Zone assets.
