_{Not much. Results begin to show in a couple of days and develop gradually over the course of two weeks. "I tell anyone preparing for a big event to have shots two weeks ahead of time," says Kane. Some observers believe Dysport sets in faster than Botox, but that has not been proven in a study. Patients taking medications that contain aspirin or NSAIDs can develop pinpoint blue bruising. Patients can wear makeup immediately but should avoid heavy workouts for 24 hours, says Carruthers.}
Alternatively, bruising could occur, though is less likely, says Rowe, especially in the hands of an experienced doctor. While he says it's "dumb luck" whether or not one bruises from an injection, he also notes that good technique helps reduce the chances. Sobel says that "if you inject [the needle with Botox] too deep, very often you can hit a blood vessel and bruise." What you do after the injection can also make a difference: Take care not to rub or massage the treated areas, as this can cause the toxin to migrate.
Note: Online coupons or deals for Botox are not recommended because you would be purchasing a medical treatment without knowing if the treatment would be suitable for your skin issues. What you think Botox will fix may not actually be the case, so don't buy something unless you know you are a good candidate for the treatment. It's better to get a Botox consultation first.
That Groupon offer might be tempting, but Dr. Tutela recommends doing a thorough vetting of your practitioner’s history and methods before signing up for treatment. “I think it is important to ask any provider if they perform that procedure frequently, to gauge their experience,” he says. He also suggests to ask if they’ve experienced any major complications and to check their online reviews. “You can get a sense of how you will be treated and what kind of experience other patients have had,” Dr. Tutela says. “Many of those low-cost, high-volume practices are loaded with horrible reviews from disappointed patients.”
Baby Botox can also be used as an upkeep strategy. "I really think of it as small maintenance doses of Botox over time instead of standard doses given at three- to six-month intervals," says Smith. "The other term that describes this well is 'tweakment' — subtle changes done over a longer period of time using lower doses of product at each treatment."
^{Botox gained popularity and notoriety as a wrinkle reducer in the late 1990s and early 2000s. But it wasn’t long before researchers recognized the potential of Botox for treating medical conditions, too. Today it’s used to treat problems such as repetitive neck spasms, eye twitching, and overactive bladder. In 2010, the FDA approved Botox as a preventive treatment option for chronic migraines.}

Spread of toxin effects. The effect of botulinum toxin may affect areas away from the injection site and cause serious symptoms including: loss of strength and all-over muscle weakness, double vision, blurred vision and drooping eyelids, hoarseness or change or loss of voice, trouble saying words clearly, loss of bladder control, trouble breathing, and trouble swallowing.
