How does Botox work?
Whenever you frown, laugh, or squint, certain facial muscles contract, creating lines on the face. Botox temporarily reduces this muscle activity by paralyzing these facial muscles, which helps to visibly smooth crow’s feet lines and frown lines.
How long does it take for Botox to work? How long does Botox last?
Botox is known as a lunchtime procedure—the actual injections take only 10 minutes. That said, results generally don’t show up for 24–48 hours. Faces look noticeably smoother within a week, with optimal results showing up after a month. In the manufacturer’s clinical studies:
- 67.9% of people had mild or no crow’s-feet on the 30th day after treatment
- 80% of people had significantly softened frown lines. The effects typically wear off in three to four months.
What are the Botox injection sites?
As noted above, the most common Botox injection sites are around the eyes and on the forehead. For a visual breakdown of injection sites, and for information regarding the number of units needed for each area, check out our Guide to Botox Injections for the Face.
Can Botox treat migraines?
Botox may be best known as a miracle wrinkler-eraser, but since 2010, it’s also been an FDA-approved treatment for those suffering from chronic migraines. For more information, read our article on How Botox Can Help a Headache.
Can Botox treat sweating?
Botox has also been used as an effective treatment for excessive sweating. When injected in the underarms, palms, or feet, the substance helps deactivate sweat glands in much the same way it hampers muscle contractions. For more information, see our Guide to Botox and Sweating.
Am I eligible for Botox?
Most adults are eligible for Botox (the manufacturer doesn’t recommend it for anyone younger than 18). Do not get Botox if you:
Are allergic to any of the ingredients in Botox or to any other botulinum toxin product (Dysport, Xeomin, etc.)
Have an infection at the injection site
Have a urinary tract infection (UTI)
Are being treated for urinary incontinence or cannot empty your bladder on your own and aren’t routinely catheterizing
Are pregnant or breastfeeding. It is not known if Botox can harm an unborn baby or pass into breast milk.
If you have other conditions, it is best to consult with your doctor before getting Botox.
