Botox takes about 24 to 48 hours to see any effect. In my opinion, treatment is maximal at about 3 weeks. If you just had service and were hoping to be transformed by Saturday night for a Bar event, I am afraid you are going to be disappointed. I would recommend in the future that you plan ahead. Generally I do not recommend getting service immediately before an event, especially an important event like meeting with judges, client events, weddings, you get the idea. Schedule treatment so that if you bruise or require a treatment adjustment, you have time for this. For BOTOX, 3-4 weeks is about right. For filler, 4 weeks is generally very good. However for a wedding (particularly your own wedding) have filler service at least 8 weeks a head of time. Collagen for the lips was the idea pre-event lip edge treatment. It stimulated almost no bruising or swelling and could be placed the day before a red carpet event. That product would only last a couple of weeks anyway. Plan ahead!
