Following treatment you can expect mild redness or swelling at the injection site, possibly some light bruising for up to a week. Do not lay flat for 4-6 hours or exercise for 24 hours post-treatment to limit the risk of the drug spreading and creating unwanted effects. Do not rub the injection sites or apply ice or cold compresses for the same reason.
Keep in mind that it can take as little as 2-3 days and as long as two weeks to see full results which is why it is recommended to follow-up with your injector two weeks after your appointment to make adjustments if necessary. Many people find that Botox lasts for 3-4 months before they need to be injected again, however this can fluctuate based on individual patient goals, needs and anatomy.
