A groove and a dark circle describe different things
The under-eye groove is a shape; the shadow is its visible effect. This distinction matters if you're choosing what to do about the darkness. No cream lightens a shadow cast by a groove.
If you're using dark circles to describe what you see, keep the cause separate from the description. A dark-looking area alone doesn't tell you how much of its appearance comes from the tear trough shadow.
A selfie can measure the visible shadow line
Yes, a selfie can measure the shadow line from the inner corner down the cheek. Treat that as a measurement of visible appearance. It isn't an exact physical measurement of the hollow beneath your eye.
The common mistake is reading a number from a photo as a permanent facial fact. If you compare images, keep the lighting and camera angle consistent. Otherwise, you can't confidently separate a change in appearance from a change in the photograph.
Established anatomy doesn't validate every score
Evidence: established. The tear trough names a defined groove, rather than a speculative facial feature. That evidence status doesn't establish the accuracy of every numerical rating applied to it.
Related terms can help you describe the area more precisely. Under-eye support is a related topic, but it isn't another name for the visible shadow. The glossary keeps these terms separate so you can check what each label means.
Read a darkness score for what it measures
The free dark-circle scan rates under-eye darkness against the cheek from a photo. It measures that visible contrast, rather than directly measuring the groove's physical depth.
Use the result to describe the image you supplied. If your question is whether the hollow itself has deepened, a darkness score alone doesn't answer it. Check what the measurement represents before using it to judge a change.
