Does Botox Prevent Wrinkles?

Absolutely. Botox (and competitors like Dysport, Xeomin and Jeuveau) are highly purified toxins that can temporarily erase or reduce horizontal forehead lines, vertical frown lines, and crow's-feet. "The injections slow muscles that contract hundreds of times a day, eventually etching lines in the skin," says New York City board-certified plastic surgeon Michael Kane, author of The Botox Book.

Basically, wherever Botox is injected in the body, it paralyzes the muscles underneath the skin. "Botox interferes with the nerve stimulation of the muscle causing excess facial expressions," Lancer explains. "When the muscle relaxes, the line diminishes."

In addition to relaxing frown lines in between the eyebrows, Botox can also lift the corners of the mouth that sag with age, smooth out the "pincushion" look in some chins, soften smoker's lines around the mouth, and soften vertical neck cords.

Is it right for you? That depends on your taste, pocketbook, and tolerance for needles. We explain all.
