How Botox Works
Botox, as well as other brands Dysport and Jeuveau, are brands of purified botulinum toxin. They work by blocking muscular signals that cause wrinkles. This action not only helps smooth overlying skin but also can help lift the brows by removing the downward pull of frown and squint muscles. Botox is even used by neurologists for the treatment of migraine headaches triggered by muscle movements. Some compelling studies show improvement of mood and depression with Botox injections and studies are underway to support this.
A Botox injection usually lasts three months or longer. Many patients find that it lasts six months or more with continued use. Lifestyle habits will play a vital role in how long Botox lasts with some studies showing high-level athletes metabolize Botox more quickly.
Is Botox Safe?
It’s very safe to use Botox for wrinkles in the FDA approved areas of the forehead, crows feet, and frown lines. Off label use on the nose (bunny lines), upper lip, golf ball chin, and vertical neck bands are also safe when performed by a skilled dermatologist.
