Botox blocks signals from the nerves to the muscles. The injected muscle is then not able to contract. This causes the wrinkles to relax and soften. Botox is typically used on the forehead lines, around the eyes, and on frown lines. Typically wrinkles are caused as we age, but they are also brought on by sun damage and gravity.
Receiving Botox actually only takes a few short minutes, and anesthesia is not required. You will simply get injected with a fine needle into the specific muscle and feel only mild discomfort.
