Rumor: Can Botox Prevent Wrinkles?

Reality: Theoretically, yes. But no long-term studies support this claim. “If you relax the muscles that continually contract, you’ll be less apt to see creases over time,” says Fredric Brandt, a cosmetic dermatologist with practices in New York City and Coral Gables, Florida. “But other strategies, like using sunscreen and keeping up proper skin care, are more reliable and certainly less expensive options for fending off wrinkles.” If you still feel compelled to go under the needle, Los Angeles and New York City dermatologist Karyn Grossman advises beginning Botox treatments no earlier than when fine lines first appear, generally in your 30s.
