Botox and Dysport are both neurotoxin injections that are commonly used for cosmetic purposes to reduce the appearance of wrinkles and fine lines. They work by temporarily relaxing the muscles that cause these wrinkles as well as other brands of neurotoxins such as Jeuveau, Xeomin, and Daxxify.Here are some differences to consider when choosing between Botox and Dysport:-Onset and Duration: Botox and Dysport have slightly different onset times and durations. Botox typically has a slightly slower onset (around 3-7 days) and may last for 3-4 months, while Dysport may have a faster onset (around 1-3 days) and a similar duration.-Spread and Diffusion: there is a consensus among injectors that Dysport may have a wider spread or diffusion compared to Botox, making it potentially more suitable for treating larger areas or for patients with more diffuse fine lines.-Unit Conversion: The units of measurement for Botox and Dysport are not equivalent, so the dosages used for each may vary. Your healthcare provider will determine the appropriate dosage for the patient's needs.-Individual Response: Individual patients may respond differently to Botox and Dysport. Some patients may find one more effective or longer-lasting than the other based on their unique physiology.-Cost: The cost of treatment may also be a consideration, as the pricing of Botox and Dysport can vary.By the same token, check the prices of Jeuveau, Xeomin, and Daxxify (longest lasting and having unique peptide to improve skin quality).-Specifically, for crow's feet, I would recommend doing superficial injections and may have the slighter advantage of wider spreading Dysport. It's important to note that the choice between Botox and Dysport often depends on the patient's needs and preferences, so it's best to consult a qualified healthcare provider for personalized advice. The patient needs to have a thorough consultation with a qualified healthcare provider who specializes in aesthetic procedures to discuss their goals, and concerns, and to determine which option is most suitable for them.
