It's mostly about the injector, honestly. The 'frozen' look usually comes from over-injecting — too many units in the wrong spots. A skilled injector uses conservative amounts, targets specific muscles, and adjusts based on your individual facial anatomy. They should also factor in your natural expressions and what movements you want to preserve. Good botox should make you look rested and refreshed, not expressionless. The first session is also a chance to assess how your face responds — a responsible practitioner will have you come back for a follow-up to check results.
