So let's start by first duplicating the background layer. Next, we will open up the filter menu, move to the noise section and select the "reduce noise" option from the list. This filter helps to remove noise in Photoshop.

What you need to do here is to balance both the strength and the preserve details options to get the maximum noise reduction.
The reduce color noise option will remove any random color pixels it can find on the image. If you increase this filter, more color noise will be reduced.

Step 5 -- Sharpen the details of the image

If you reduce noise, the sharpness of the image is also reduced. There is where the sharpen details option comes in handy. You can restore the sharpness of the image with this filter.
The Remove artifact option will remove the halos and blocky parts of the image when saving it in a lower quality JPEG format.

Step 6 -- Set the detail of each color

Moving on, you can move to the advance section and open up the "per channel" tab. Here you can enhance the image by adjusting the details of each color channel. You can work individually with the reds, greens and blues, adjust the strength and preserving the details accordingly.
Once done, press ok and it will reduce noise in Photoshop from the image.
And that's it.
