Peppering/ blem getting worse.

A couple months ago I made a post about me being concerned that some small black dots came up on my unit. People advised me that it was just peppering and is completely normal. However I have since started to notice that more dots have been “appearing” taking the count from 3 up to 7. I am growing increasingly concerned with this and was wondering if there is anything I can do/ shouldn’t be doing to fix it. Thanks all
