Dynamic refers to your expression lines– the lines that come out when you smile, laugh and frown, whereas static lines remain visible even when you’re on a resting face. These two kinds are treated differently.
Botox is a brand and has derived its name from botulinum toxin from Clostridium botulinum bacterium which, when injected, blocks the release of acetylcholine (neurotransmitter) where the motor neuron and muscle fiber meet.
Once blocked, it inhibits the contraction of muscle; hence, relaxing it and making it difficult to smile, frown, or raise your eyebrows. As a result, lines are visibly reduced.
Fillers, on the other hand, are mainly composed of hyaluronic acid.
