We've all heard of Botox and we know celebrities have been using it for over a decade now to keep their youthful appearance. But how did this youth in a syringe come about?
Botox is a brand name of a toxin produced by the bacterium Clostridium botulinum. Despite the fact that one of the most serious complications of botulism is paralysis, scientists have discovered a way to use it to human advantage. Small, diluted amounts can be directly injected into specific muscles causing controlled weakening of the muscles.
The FDA approved such usage in the late 1980s upon the discovery that Botox could stop ailments like blepharospasm (uncontrolled blinking) and strabismus (lazy eye). Doctors have been using Botox for years to successfully treat wrinkles and facial creases. In April 2002, Botox gained FDA approval for treatment of moderate-to-severe frown lines between the eyebrows- called glabellar lines. However, Botox is often used for other areas of the face as well.
How does Botox work to smooth out wrinkles?
Botox blocks signals from the nerves to the muscles. The injected muscle can no longer contract, which causes the wrinkle to relax and soften. It is most often used on forehead lines, crow's feet (lines around the eye) and frown lines.
How is a Botox procedure performed?
Getting Botox only takes a few minutes and no anesthesia is required. Botox is injected with a fine needle into specific muscles with only minor discomfort. It generally takes three to seven days to take full effect and it is best to avoid alcohol at least one week prior to treatment. Aspirin and anti-inflammatory medications should be stopped two weeks before treatment as well in order to reduce bruising.
How long does a Botox injection last?
The effects from Botox will last four to six months. As muscle action gradually returns, the lines and wrinkles begin to re-appear and wrinkles need to be re-treated. The lines and wrinkles often appear less severe with time because the muscles are being trained to relax.
What are the side effects of Botox?
Temporary bruising is the most common side effect of Botox. Headaches, which resolve in 24-48 hours, can occur, but this is rare. A small percentage of patients may develop eyelid drooping. This usually resolves in three weeks. This usually happens when Botox moves around so you shouldn't rub the treated area for 12 hours after injection or lay down for three to four hours.
Who should not receive Botox?
Patients who are pregnant, breastfeeding or have a neurological disease should not use Botox. Since Botox doesn't work for all wrinkles, a consultation is recommended.
Will insurance pay for Botox?
Insurance coverage varies for Botox injections, depending largely on the medical necessity of your condition. Botox is not generally covered by insurance when used for cosmetic purposes. Check with your insurance carrier for coverage details.
