I'm curious about the difference between a double chin lift and Botox.

I am curious about the difference between double chin lifting and Botox among dermatological procedures. I would like to know the principles by which each procedure works and which specific areas they are actually more beneficial for. I understand that they both provide a similar effect of refining the facial lines, but I am confused about whether the resulting changes are the same or different. I am also curious about the difference in expected results when receiving a double chin lift versus Botox separately, and under what conditions one is the more suitable choice. I am also interested to know if there are differences in the duration of effects or satisfaction levels between the two procedures, and what the actual noticeable effects are when comparing the two treatments.
