How neurotoxins actually work
All three products are forms of botulinum toxin type A. Injected in small, measured amounts, they block the nerve signal that tells a muscle to contract. The muscle stays relaxed, the skin over it stops creasing, and the line softens. They work on lines caused by movement. A line that is visible when your face is completely still is a change in the skin itself, and that responds to microneedling or RF skin resurfacing instead. Most people who want both end up combining them.
