Botox is a cosmetic treatment made from botulinum toxin. It temporarily relaxes muscles, reducing the appearance of fine lines and wrinkles. By blocking nerve signals to the targeted muscles, Botox prevents them from contracting, creating a smoother, more youthful appearance. The effects typically last 3 to 6 months before the muscles regain activity, and the procedure is commonly used on areas like the forehead, around the eyes (crow’s feet), and between the eyebrows.
