For both hyaluronic and botulinum injections, the aim is to eliminate or significantly reduce the appearance of wrinkles and lines, and to improve the condition and appearance of your skin. However, the effects of these treatments are quite different, so your specialist will offer advice on which injection is the right choice for you. One of the differences that can help to decide which injection is preferable is the different effects of these substances. Hyaluronic acid injections have an advantage in that they can be used not only for the reduction of wrinkles and lines, but also for facial contouring to improve the shape of the lower jaw, cheeks, nose and lips. Botox doesn’t offer the same benefits, but it’s a great solution for correcting facial wrinkles and lines, as well as combating extensive sweating or teeth grinding at night.
