Several small injections of 10 to 15 units of Botox per eye or 30 to 50 units of Dysport can help relax muscles and reduce wrinkles. Both Botox and Dysport are FDA-approved neuromodulators or neurotoxins (forms of botulinum toxin type A) that are used to minimize fine lines and wrinkles. Dysport works by paralyzing the muscles that form them, preventing them from contracting. When it comes to clinics that price products per unit, you will find that the cost per unit of Dysport is usually lower than the price per unit of Botox.
However, to obtain a similar treatment result, the final cost may be approximately the same. The Journal of Clinical and Aesthetic Dermatology has more information on the differences between Dysport and Botox. The dosage of Dysport is not the same as the dosage of any other botulinum toxin product and cannot be compared to the dosage of any other product you have used. Dysport also tends to spread, making it easier to address larger surfaces (such as the forehead) with less quantity. This makes Dysport ideal for treating larger areas, such as the forehead, as fewer injections are needed to treat a larger treatment area.
Therefore, if a patient is used to a certain number of Botox units for a treatment, they will likely need to increase the number of units when switching to Dysport (or vice versa).The number of Dysport units needed depends on the person, but it's common to see that about 50 units are used for the lines between the eyebrows. The most serious side effects associated with Dysport are due to something known as the toxin propagation effect, in which areas away from the injection site experience reactions such as muscle weakness, double or blurred vision, and loss of bladder control. The study subjects were injected with Botox on one side of the face and Dysport on the other side. In the end, the choice between Botox and Dysport can come down to the simple preference of both the injector and the patient. One thing to keep in mind is that Dysport and Botox are measured differently, so a forehead that needs 50 units of Dysport might need just 25 units of Botox.
