Is it a bad idea to get cosmetic injections before a major social event?

Two weeks is probably the minimal amount of time needed to see the results of fillers and Botox.

Generally, Botox will take 2-3 days to produce noticeable effects, which will improve over 1-2 weeks.

As mentioned by others, I do not see patients for at least 10 days before considering additional treatment.

While bruising is always a possibility, the risk is fairly minimal with Botox and an experienced practitioner should not produce much if any bruising. The big thing with Botox is that you may not notice the full effect for 1-2 weeks. Fillers are a much different story.

Bruising is a common occurrence and cannot be predicted pre-treatment. There are several things physicians and patients can do to decrease the risk of bruising but this is still an uncontrolled variable. Some bruises may take 1-2 weeks to disappear and may not fully cover with makeup during that time. Patients may also experience localized swelling which may also take some time to dissipate.

If it is vitally important not to have any evidence of the procedure, 2 weeks is a good time period to wait between Botox and injection procedures and big events.

Do NOT get the injections within 10 days of a major social event. While bruising doesn't usually occur. . .it's more likely if you ABSOLUTELY can't have it. Isn't that how it always works? :-)

You want time for the Botox to take effect and have a touch up if you need it. We don't typically see a patient for two weeks so we are confident that all of the Botox has taken effect. I would try to have the treatment a month before the major event if you can plan it in advance.

It really depends upon which injectable you're talking about. BOTOX Cosmetic can easily be injected by an experience injector with very little risk for bruising and other side effects. As such, it is very common for me to inject my patients right before a major event. Fillers are a different story. These tend to be associated with varying degrees of swelling and bruising and so should be injected at least 2-3 weeks before an event. In addition, once in a while it is necessary to touchup an uneven result and so a little extra time to get that perfect result before that big event can be very helpful!

This is a tricky decision inasmuch as one wants to look their best but may not want to risk an unexpected outcome. If the patient has had the same procedure before (Botox or fillers) and was happy with the result - doing the treatment no sooner than 2 weeks before the event should be fine. In this way, if there was any unexpected bruising or swelling, it will have resolved. Also, the full effects of these products will be at the 2 week mark.
On the other hand, if someone is new to this procedure or doing this with less than 2 weeks before the event, I would recommend waiting.
