The Science Behind Botox – How It Works on Wrinkles

Botox is a popular cosmetic procedure that reduces the appearance of fine lines and wrinkles. It is injected directly into the muscles that cause the skin to become stiff and wrinkly.

Botox works by temporarily blocking nerve signals and muscle contractions. This minimizes the appearance of lines around the eyes and between the eyebrows and slows new wrinkle formation.

Botox is a Neurotoxin

Botox is a neurotoxin, and when used correctly in small doses, it can help reduce skin wrinkles. It also helps treat some medical conditions, including eyelid spasms, excessive sweating, bladder disorders, and migraines.

Wrinkles are formed when collagen – the protein in your skin that keeps it firm and supple – starts to thin over time, especially as you age. Botox can soften and smooth the lines and wrinkles caused by collagen thinning, such as horizontal forehead lines, vertical frown lines, and crow’s feet.

Botox blocks the release of acetylcholine, a chemical messenger that causes muscles to contract. This blockade prevents muscle contraction, which leads to fewer lines and wrinkles.

It Relaxes Muscles

Botox works by temporarily relaxing facial muscles. This reduces wrinkles and helps you look younger for up to 3 months.

Wrinkles form when muscles contract during repetitive facial expressions like frowning or smiling. When injected into these muscles, Botox blocks the nerve signals that make them contract.

When a muscle contracts, it releases acetylcholine, a neurotransmitter. This chemical signal sends instructions to the underlying muscles.

During treatment by aesthetic services like Liv & Lo, a dermatologist injects very small amounts of Botox into the specific muscle causing wrinkles. This quick and painless procedure is done right in the doctor’s office.

This neurotoxin is produced by a bacterium called Clostridium botulinum. It’s purified and used for injections only by licensed healthcare providers. It’s not dangerous by itself, but if the toxins get into the bloodstream, they can cause botulism – a serious nervous system disorder that affects breathing.

It Blocks the Release of Acetylcholine

A neurotransmitter called acetylcholine, which is released when muscles contract, is what Botox does to work. It can be injected into facial muscles to make them stop contracting and reduce the appearance of fine wrinkles.

In the skin, acetylcholine is released from nerve cells and attaches to receptors in muscle cells. When the muscle cells move, acetylcholine sends signals to these nerves to tell them where to send signals.

When injected into a muscle, Botox blocks the release of acetylcholine at the nerve synapse and prevents signals from reaching the nerves. This results in temporary paralysis of the muscles. Botox’s effects last for 24 hrs and two weeks, depending on the type of injection.

It Prevents New Wrinkles

Most people get Botox injections to reduce the appearance of existing wrinkles. But if you’re looking for a more permanent way to keep your skin smooth, it’s also a good idea to consider preventative Botox.

It also blocks the release of acetylcholine, the neurotransmitter that causes wrinkles to form.

But preventative Botox isn’t a substitute for strong skincare and sunscreen, which are important to protect your skin from the sun’s damaging rays.

Ask your doctor if preventative Botox is appropriate if you’re thinking about doing so. Most specialists concur that starting in your mid-to late-20s is the optimal age.
