Face Yoga / Facial Exercises
One small trial showed modest fullness improvement in middle-aged women; hypertrophying mimetic muscles can also deepen expression lines.
Evidence grade C
Mechanistic plausibility, small or observational studies
Mechanism
Repeated resistance of facial muscles may slightly increase muscle volume under the skin, marginally offsetting age-related volume loss.

The full read
A 20-week Northwestern study found participants looked ~2.7 years younger by dermatologist rating — but it was tiny (n=16 completers), unblinded-adjacent, and in 40–65-year-olds with volume loss. For young faces there's little to gain, and overworking mimetic muscles can etch dynamic wrinkles (the exact thing botox exists to stop). Low priority.
