With the outbreak of World War II, weaponization of botulinum toxin was investigated at Fort Detrick in Maryland. Carl Lamanna and James Duff developed the concentration and crystallization techniques that Edward J. Schantz used to create the first clinical product. When the Army’s Chemical Corps was disbanded, Schantz moved to the Food Research Institute in Wisconsin, where he manufactured toxin for experimental use and generously provided it to the academic community.
Properly trained, board-certified dermatologists and plastic surgeons separate the "forehead" area into the upper/main forehead, and the glabella, the area between the eyebrows that has the frown lines. Depending on your exact anatomy and types of lines and facial movement, you may need only 3 to 5 units total in the upper forehead area, or up to 40 units for the combined glabella... READ MORE
The most commonly reported side effects for JUVÉDERM® injectable gels were injection-site redness, swelling, pain, tenderness, firmness, lumps/bumps, bruising, discoloration, and itching. For JUVÉDERM VOLBELLA® XC, dryness was also reported. For JUVÉDERM VOLUMA® XC, side effects were predominantly moderate in severity, with duration of 2 to 4 weeks; for JUVÉDERM® Ultra XC , JUVÉDERM® Ultra Plus XC, or JUVÉDERM VOLLURE™ XC, they were mostly mild or moderate in severity, with duration of 14 days or less; and for JUVÉDERM VOLBELLA® XC, they were predominantly mild or moderate, with duration of 30 days or less.
Still, Botox's use for depression raises a question that confounds some researchers. In some cases, how Botox works is evident: the toxin can block the signals between nerves and muscles, which is why it can help calm an overactive bladder, say, or a twitching eye, or the facial muscles that make wrinkles more apparent. In other cases, however (with migraines as well as with depression), scientists are flummoxed. They may have noticed that the drug works for a given condition, but they aren't always sure why--in sciencespeak, they don't know what the mechanism is.
Contrary to popular belief, the bacteria that causes botulism, clostridium botulinum, is not part of the treatment, nor are six of the seven neurotoxins it secretes. The only substance used in Botox injections, botulinum toxin A, is carefully extracted, purified, and standardized into FDA-approved doses. Plus, the dosage is so small, it can't get beyond the muscle tissue it's injected into, meaning there's little if any chance for Botox to reach the bloodstream.
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 the Botox moves around so you shouldn't rub the treated area for 12 hours after injection or lay down for three to four hours.
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.
