How to fix the noise in the nano banana generated images

I have noticed that images generated using Artificial Intelligence (AI), specifically those I edit in Photoshop, consistently display digital noise or visual artifacts.

Although I have tried using the upscaling features (such as 'Image Size' or 'Super Resolution') in Photoshop to mitigate this issue, the results are still not satisfactory.

I would like to know what methods or techniques others use to effectively remove the noise from these AI-generated images, in order to achieve a cleaner and more professional finish.
