Botox vs. Dysport: What’s the Real Difference?

Botox and Dysport are two of the most popular wrinkle-relaxing injectables — and while they work in similar ways, they aren’t identical. Both reduce dynamic wrinkles by relaxing the underlying facial muscles, helping you achieve smoother, more refreshed skin. The key differences come down to how they’re formulated, how quickly they work, how far they spread, and how long they last.

Botox offers precise control, making it ideal for smaller treatment areas like crow’s feet or eyebrow lines. It typically takes 5–7 days to show results.
Dysport spreads a bit more and acts faster, with results appearing in 2–3 days, and is great for larger areas like the forehead or frown lines.

Another major difference is unit measurement:
1 Botox unit ≠ 1 Dysport unit.
Dysport units are measured differently, so more units are used — but that doesn’t make it weaker.

How long they last:

• Botox: ~3–4 months

• Dysport: ~4–5 months

Both can look natural when injected by an expert. Dysport tends to give a softer, more blended finish, while Botox provides sharper control for detailed sculpting.

Ultimately, the best choice depends on your goals, facial anatomy, and the injector’s technique. At CN Medical Aesthetics & Wellness, treatments are personalized to ensure results that look smooth, balanced, and never “frozen.”
