BOTOX is a prescription drug made of the bacterial toxin “botulinum.” It’s commonly used to treat muscle conditions or to improve the appearance of wrinkles by temporarily paralyzing muscles in the face. “As we age, these muscles that have been working so hard over the course of our lives cause the overlying skin to wrinkle, and that ages the face,” says Mistica LaBrasca, MPAS, physician assistant, UPMC Cosmetic Surgery and Skin Health Center. “So by temporarily relaxing these muscles, we can soften or even completely eliminate the lines temporarily.”
