Botox Cosmetic (onabotulinumtoxinA) is an injectable medication that’s made of toxins from a bacteria called Clostridium botulinum. At high doses, this toxin can cause a serious infection known as botulism. But Botox injections are given in very small doses and isolated to certain muscles. So, botulism is very rare if the injections are administered properly. Botox works by blocking nerves and temporarily stopping the muscle where it’s injected from contracting. It’s commonly used for cosmetic purposes like smoothing facial lines.
Dermal fillers also treat wrinkles on the face. They’re primarily used to treat smile lines, though the fillers can also be used to plump up the lips or cheeks. Sometimes, they’re used for hand treatments or to reduce the appearance of scars. Dermal fillers aren’t approved for plumping up other areas of the body, though, such as the breasts.
