Botox & Dysport

Botox and Dysport are both injectables that work by decreasing carefully selected muscle contraction. One of the major causes of wrinkling on the face is repetitive facial movement. Botox and Dysport lessen the strength of the contraction (and can inhibit it completely with enough units) to soften lines. Dr. Dempsey performs all cosmetic injections herself.

When should I start?

Botox or Dysport should be considered as soon as you start to see a line at rest (meaning without muscle contraction). The longer you wait, the less impressive the results. It can also be done preventatively, starting as soon as one sees significant lines with muscle contraction (raising eyebrows or frowning).

Does it hurt?

Barely. It is very tolerable and no worse than a tiny mosquito bite. Dr. Dempsey uses the tiniest needles possible to minimize bruising and discomfort. Numbing cream can be applied if needed but 99% of patients do not require this.

How long do injections take?

Less than 5 minutes. On your first visit, expect to discuss expectations and goals with Dr. Dempsey at length but the actual injections are very quick.

What should I expect afterwards?

You can go straight back to work or out to dinner that night. You may have slight redness but that fades quickly and can be covered easily. Please avoid lying down, exercise, massage and flying for 4 hours after injection. It will take 3-4 days to start taking effect and 10-14 days for the full effect. Be patient. You will follow-up 2 weeks after your first treatment to tweak if needed to ensure it is perfect.

How long does it last?

Muscle relaxation lasts 2-4 months depending on how many units were placed (less units provide a more natural result but do not last as long). On average, patients return for injections 2-4 times a year.

How should I prepare for my appointment?

There is no special preparation but patients who are taking supplements or medications that can increase bleeding are at higher risk of bruising. You should inform Dr. Dempsey before treatment if you are using: Aspirin, Ibuprofen, Vitamin E, Fish Oil, Ginkgo, Green Tea, Garlic, Ginseng, St John’s Wort, or Alcohol. If possible (though not necessary), you should avoid aspirin containing products for 14 days before your procedure, NSAIDS (Ibuprofen, Motrin, Aleve, etc) for 7 days prior to your treatment. Avoid alcohol 48 hours prior to treatment.

Is botox safe in pregnancy?


Once I start, do I have to continue getting regular injections?

Absolutely not. It is a myth that wrinkles will look worse as they return. In fact, they often look better as Botox and Dysport are just a way to “freeze time” temporarily so to speak. 

How many units will I need?

Every patient is different and Dr. Dempsey takes a very personalized approach to ensure natural, beautiful results are achieved. While one person may need x amount of units, the next will likely need y- there is no cookie cutter approach to cosmetic dermatology.
