How soon can I expect to see real results from my Dysport treatment for crows feet?
While Dysport normally can start working as soon as 2-3 days post-treatment, it can take up to 14 days for it to take full effect. This is because the toxin needs time to bind to nerve endings and gradually relax the muscle, so results build gradually rather than appearing overnight. During this window you'll likely notice the lines softening a bit more each day, especially when you smile or squint. Everyone's timeline varies a little depending on muscle strength and metabolism, so don't worry if you see less movement than a friend did at the same point.
If after 14 days, you still do not see any change, then definitely contact your injector to add more units. It's also worth mentioning at that visit if the lines are softer in some spots than others, since that can help guide adjustments for your next treatment.
Clinical Context
Botulinum toxin needs time to bind nerve endings and gradually relax the treated muscle, which is why results build over one to two weeks rather than appearing instantly. Everyone's timeline varies slightly based on muscle strength and metabolism. If crow's feet lines are still visible after two weeks, your injector can evaluate whether a touch-up with additional units is needed, or whether the treatment pattern should be adjusted next time.
