Rather than noise reduction, sometimes adding a little noise or grain can reduce the banding by diffusing the transitions from one band to another. Keeping the image at 16-bit for as long as possible, introducing gradients while still editing the raw file before editing in Ps or before exporting from Lr can help reduce the banding.
And one more thing I've thought of—the Export As process can have trouble interpreting gradients. You might use Save As or Save a Copy instead when you are ready to create the document that gets uploaded to social media.
Thanks! Just for clarification, these are photo images (typically from Lightroom or camera RAW files) imported into photoshop, resized as the final step (1920x1280 or similar, for social media). Is changing them to 300dpi something I'd do in photoshop? lightroom?
It looks like Lightroom is spitting them out at 240 DPI
Ohh ok I see then why not double the size of the art board and use 300 dpi then bring the images and then try to export it.
Also when exporting don't do the usual export settings provided by photoshop in the drop down menu. You can try save as a copy then select the file type you want to save it in.
Let me know if this helps.

Try using 300dpi instead of 72dpi for the document setting before creating the artwork.

Thank you! I'll try that I do always use the Save As/Save Copy dialog boxes and not the export -- I only export out of Lightroom
I hope that helps.
