This study looked at how much Botox people get in their forehead and found that older people and those with stronger forehead muscles and deeper wrinkles need more shots.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

People with stronger forehead muscles and deeper wrinkles between the eyebrows tend to get more Botox injections than those with weaker muscles and lighter wrinkles.
On average, people get about 7 units of Botox between their eyebrows and about 4 units in the forehead line above the nose, and men and women get roughly the same amount.
Older people tend to get more Botox injections than younger people when treating frown lines.
Repeated facial muscle contractions induce dynamic wrinkles that, over time, become fixed static lines due to collagen and elastin degradation; neuromodulators such as botulinum toxin prevent this progression by inhibiting neuromuscular transmission.
