Botox vs. Dysport: Which Wrinkle Treatment Works Faster and Lasts Longer?

Botox and Dysport remain two of the most popular treatments for reducing facial wrinkles. Both use botulinum toxin to smooth dynamic lines—those that form when frowning or raising eyebrows. While they share the same core ingredient, key differences set them apart in cost, speed, and approved uses. The US Food and Drug Administration (FDA) has cleared Botox for treating forehead lines, crow’s feet, and glabellar lines (the vertical furrows between the brows). Dysport, however, is only approved for glabellar lines. Despite this, both injections work best on expression-related wrinkles rather than deep, static creases.

Results from either treatment typically last around four months. Dysport often shows effects slightly faster, though individual responses vary. The difference comes from their formulations: Dysport’s protein structure allows it to spread more than Botox, which may suit larger treatment areas. Experts recommend starting botulinum toxin injections in your 30s or 40s to prevent lines from becoming permanently etched. When administered in small, controlled doses, these toxins are considered safe. However, only a board-certified healthcare provider—such as a dermatologist or plastic surgeon—should perform the procedure to ensure proper technique and dosing. Costs for a single session average $466, according to the American Society of Plastic Surgeons. Prices can fluctuate depending on the clinic, geographic location, and the number of units required.

Both Botox and Dysport offer temporary but effective solutions for smoothing facial wrinkles. Their differences in diffusion, onset time, and FDA approvals help patients and providers choose the best option. For lasting results, early and consistent treatment under professional guidance remains key.
