Botox

Botox is an injectable medicine that is probably best known as a treatment for fine lines and wrinkles that form due to facial movements when you make expressions, such as frowning, smiling, and squinting.. 

Botox works by stopping your nerves from releasing some brain chemicals (neurotransmitters) that cause your muscles to contract. This paralyzes the muscle so it stays relaxed. This makes the wrinkles on your face softer and smoother so they're less visible.

You will start to see the affects between 4-7 days., but it will take around 14 days for the full affects to be seen.

The effects from Botox generally last about 3-6 months. 

The needle that's used for Botox injections is very thin and the injections aren't done very deep, so most people say the injection doesn't hurt. A topical numbing cream is applied prior to the injections being done , but you may feel a pinch or sting. It's usually over in just a few minutes.
