Ever wondered how Botox works? We all know it is used by hundreds of thousands of people throughout the world each year to reduce wrinkles resulting in a more youthful, refreshed appearance, but do you know how it actually works? No, well read on to understand the science ….
Botulinum toxin (Botox) is a neurotoxic protein that blocks the action of acetylcholine (a-sea-tyl-co-leen), a tiny molecule that stimulates muscle fibres. Therefore, nerve conduction is halted, and ultimately muscle contraction cannot occur. Superficially this is reflected in smoother, younger looking skin with fewer wrinkles.
The action does not occur immediately, progressive inhibition of acetylcholine release from nerves usually manifests itself 2-3 days after injection, and maximal effects are seen at 10-14 days. This is why it takes up to 2 weeks to see the full result of your Botox.
Over time, your nerves regenerate and acetylcholine molecules begin to function again. Whilst muscle movement is reduced for up to three, or even four, months, gradual return of movement (and thus facial wrinkles) is seen after 30 days. It is therefore perfectly normal that after 4-6 weeks you may notice some slight muscle movement and wrinkles returning.
