Botox attaches itself to nerve endings and relaxes the muscles that cause wrinkles. Though considered a neurotoxin, Botox is generally safe as it stops the hormone production that causes frowning and grumpy facial movements that lead to an aging appearance leading to an amazing youthful look. Botox is also applicable for medical rather than cosmetic purposes. Consult your doctor on how Botox can help you, especially as a treatment for chronic migraine.
