Export photo several times

[Maya27796656w6ti]

I wonder if a photo lose quality if I export the same photo several times?

For example, if I edit and export a photo from Lightroom, but I am not happy with the result, so I edit some more and then export a new photo. Does the new exported photo have the same quality as the first exported?
If I export the same photo (but have re-edited) 10 times, does the 10th exported photo have the same quality as the first exported photo?

Thanks in advance!

No issue. The original image remains the same throughout the editing and re-editing process, because Lightroom doesn't change the original image. Edits are stored in the catalog and are only applied when creating the derivative image during export....so if you continue to work with the same original image you can re-edit and export as many times as you want and there will be no quality degredation.
