OK, you were speaking about those white spots all around, am I right?
If so, it might be easier in attenuating them
I give you three methods which work very differently for "different" purpose, even though the two later are very similar using the same filter but for a very different purpose.
1) For the small spots and selected area, I'll make a selection and go with the Filters ➤ Distorts ➤ Value Propagate... (select More Black for darker area and select More white for whiter/brighter area like hands)
2) Still using a selection on small spotted areas, this is another option
Make a selection go to Filters ➤ Blur ➤ Median Blur...
3) This time it's for the whole picture (works with area/selection as well)
Duplicate your photo, on the top duplicated photo, go to Filters ➤ Blur ➤ Median Blur... BUT this time put the mode in Subtract mode => you will got a black image with some white spots parsed,
you will need to increase the brightness a bit I'll do it with Colors ➤ Curves...
Once it's done put that top black layer in Subtract Mode (yes in the filter and now in the layer's stack )
Hope this can shorten your work.
