Nostril botox targets the small muscle that makes the sides of your nose flare out when you smile or take a deep breath. Rather than reshaping or narrowing the nose, it only dials down that muscle's pull, which is what sets it apart from other nose treatments. Here is a breakdown of which muscle is responsible and exactly how botox acts on it.

Botox works by blocking the signal pathway between nerves and muscles, temporarily stopping muscle movement. How long the effect lasts depends on the dose, the size of the muscle, and how quickly the nerve recovers, so results vary from person to person. Here is how repeat treatments, antibody formation, and aftercare all affect how long Botox lasts.

Jaw slimming Botox blocks the nerve signal that tells your chewing muscle to contract, weakening its grip. As the muscle loses strength, it slowly shrinks, softening a square-looking jawline into a slimmer contour. Here's the science behind when results appear and why duration varies from person to person.

Bunny lines are the horizontal creases that appear across the nose bridge when you smile or scrunch your nose, caused by contraction of the muscle that presses down on the nasal bridge. Here's why that muscle fires, how Botox reduces its movement, and what to know about dosing, duration, and side effects.
By Dr. Lee
Forehead lines form when the frontalis muscle contracts over and over with everyday expressions. Botox works by blocking the nerve signal that tells this muscle to move, not by dissolving the wrinkle itself. Here is how the muscle gets quieted down and why the effect eventually wears off.

A gummy smile happens when your gums show more than usual as you smile, and an overactive lip-lifting muscle is one of the most common causes. Botox works by slightly reducing the strength of that muscle so your lip doesn't rise as high when you laugh. Here's how to tell whether muscle is really the cause, plus how long the results tend to last.
By Dr. Lee
A look at whether Botox can treat a gummy smile, which causes respond best, which lip-elevating muscles get treated and with how many units, injection points like the Yonsei point, and how long the effect lasts, based on published studies.

Hairline Botox does not actually move where your hair grows. It relaxes the forehead muscles, which changes the surrounding features enough to make the hairline read differently. Here is how eyebrow position and forehead lines shift together to make the hairline look more balanced, along with the theory behind scalp Botox for hair loss.

Botulinum toxin, sold under the umbrella term Botox, is actually made a bit differently from one country to the next. The bacterial strain, the purification process, and how much complexing protein is left behind are known to affect how far the toxin spreads and how likely antibodies are to form. Here's a breakdown of what really sets Korean, German, British, and American toxins apart.
