Botox injections are primarily used to reduce the appearance of wrinkles and fine lines, particularly on the forehead, around the eyes (crow's feet), and between the eyebrows. The procedure involves injecting a purified form of botulinum toxin into specific muscles, which temporarily paralyzes them. This reduces muscle activity, leading to a smoother, more youthful appearance. Results typically last three to six months, after which treatments can be repeated.
