What's the best concealer for dark under-eye circles?

Across the reviewers we read, the most consistent recommendations for dark circles are Maybelline Instant Age Rewind (for a brightening, lightweight finish) and IT Cosmetics Bye Bye Under Eye (for heavier, full-coverage masking). Tarte Shape Tape gets praised for coverage but multiple specialist-subreddit threads note it can read heavy or settle into fine lines on the under-eye specifically.
