What magnification level do I actually need in a travel mirror?

Across the reviewers we read, 1x/10x is the most-recommended combination for everyday makeup application - you get a full-face view plus enough zoom for eyeliner, brows, and lash work. 30x magnification shows up repeatedly in pitches for plucking, contact lenses, and skin inspection, but specialist subreddit threads warn it's overkill for makeup and forces you to work very close to the glass. 3x is generally considered touch-up territory and pairs well with pocket compacts.
