I don't know. You've taken a photo so close that I can see her nasal hair. Besides, a die chip is just an abused die, anyway.
Let me rephrase that. From your images using your USB microscope, I can't tell if it is circulation damage or not. You see, most of the USB scopes use digital enlargement rather than optical enlargement. In my opinion, digital enlargement leaves a lot to be desired. Below are images using my stereomicroscope with optical zoom capability. Can you see the difference?
You don't have to apologize. I just wanted to let you know that there are other alternatives to USB microscopes. I understand that it is all you can afford.
The only way i could get that picture is with my usb microscope run down threw the eyepeice of a scope, no way to light it but with the microscope, which causes the glare you are seeing. I have a smaller eye scope i will try to use and see if it helps with the glare
