In laypersons terms, the botulinum toxin simply keeps the muscles that cause frown lines from contracting. This causes the skin to become smoother. Normally your brain sends electrical messages to your muscles so that they can contract and move.The muscle relaxant keeps that message from getting to the muscle that causes the wrinkles. Several tiny injections of the muscle relaxant are made directly into the muscles that cause those moderate to severe frown lines between the brows.
Your cosmetic injector will determine where to administer the injections by examining your ability to move certain muscles in your brow area. The location, size, and use of the muscles that create a furrowed brow vary markedly among individuals.
No anaesthesia is required, although your injector may choose to numb the area with a cold pack prior to injecting. Discomfort is usually minimal and brief. You can expect to be in and out of the clinic without downtime. You may see a marked improvement in the moderate to severe frown lines between your brows within days. Improvement may continue for as long as a month, and could last up to 4 months.
