Botox is a drug made from a neurotoxin produced by the bacterium Clostridium botulinum called botulinum toxin. "It's a poison secreted by the bacteria," plastic surgeon Norman Rowe, M.D., tells SELF. Botulinum toxin has proven to be a successful and valuable therapeutic protein when dosage, frequency of treatment and variety of treated clinical conditions are considered, according to Howard Sobel, M.D., a dermatologist in New York. Basically: when it's done right. When it's done wrong—like, really, really wrong—it can cause "botulism-like symptoms," according to Mayo Clinic, which may include muscle weakness, trouble breathing, speaking or swallowing, bladder control issues, and vision problems. That is "very unlikely," but a more than convincing enough reason not to go bargain hunting for Botox.
BTX-A has also been used in the treatment of gummy smiles,[80][81] the material is injected into the hyperactive muscles of upper lip, which causes a reduction in the upward movement of lip thus resulting in a smile with a less exposure of gingiva.[82] Botox is usually injected in the three lip elevator muscles that converge on the lateral side of the ala of the nose; the levator labii superioris (LLS), the levator labii superioris alaeque nasi muscle (LLSAN), and the zygomaticus minor (ZMi).[83][84]
Unopened vials of BOTOX should be stored in a refrigerator (2° to 8°C) for up to 36 months. Do not use after the expiration d ate on the vial. Administer BOTOX within 24 hours of reconstitution; during this period reconstituted BOTOX should be stored in a refrigerator (2° to 8°C). Reconstituted BOTOX should be clear, colorless, and free of particulate matter.

Lastly, a Botox treatment does not offer permanent results. Botox is most effective when treatments are carried out at regular intervals before the results fully wear off. On average, the results last for three to four months,  although Botox metabolizes at different rates in different individuals. The first ever Botox treatment you receive may not last as long as subsequent treatments, plus you may require touch-ups two weeks after the procedure as your injector determines the right dosage for you. Over time, however, many patients notice that they can wait longer intervals between treatments as their treated facial muscles weaken.
On November 23, 2015, Allergan and Pfizer announced their intention to merge in a $160 billion transaction, the largest pharmaceutical deal and the third largest merger in history.[19] On April 5, 2016, after the Obama administration announced its plan to ban tax inversions, Pfizer terminated the acquisition and paid Allergan a $150 million breakup fee.[20]
BOTOX® Cosmetic targets one of the underlying causes of frown lines, crow’s feet and forehead lines — the repeated muscle contractions from frowning, squinting, smiling and raising the eyebrows over the years. Your specialist will inject these muscles with BOTOX® Cosmetic to temporarily reduce muscle activity. You will begin to notice a visible smoothing of the frown lines between your brows, your crow’s feet lines and your forehead lines.
In my experience, this, like all other treatments we use in medicine, doesn’t benefit every patient. I find that it helps a majority of appropriate patients, that is, those patients with a diagnosis of chronic migraine who have failed not just abortive but also preventative migraine treatments. Is there sufficient benefit, however, to outweigh the cost and pain of this treatment? In the case of most of my patients, the answer is yes.
There are many physicians who encourage their patients to either work the area several times during the next several days or, alternatively, to not use the affected muscles during the next several days. Many practitioners do not tell the patients to do anything in particular other than to avoid strenuous activity for several hours afterward because of an increased risk of bruising.
Charges can vary from $8 to $20 a unit depending on where you are in the country and the level of dilution, meaning that the price may actually be higher than the quoted price if a clinic dilutes it out instead of preparing full-strength Botox. The cost of the procedure varies as it depends upon the total number of units injected and the number of sites treated.

Investors have been unhappy with Allergan's stock performance over the last year, and some have expressed interest in seeing the pharma company explore splitting up. On Wednesday, Allergan announced it plans to sell its women's health and infectious disease businesses. The news sent Allergan's stock down 2%, suggesting the move didn't go as far as some would like.

According to the PREEMPT paradigm, one injection of 5 units of onabotulinumtoxinA into four sites (total 20 units) into the frontalis muscle is done. The injection points are located by visually drawing a line up from the medial edge of the supraorbital rim. Patients will be injected into the muscle in the upper third of the forehead at least 1 to 2 fingerbreadths above the corrugator injection site. The lateral muscle injection areas are parallel and approximately 1 fingerbreadth lateral to the medial injection site, which is roughly in line with either the midpupillary line or the lateral edge of the cornea, which is the limbus line. In cases in which I am worried about ptosis, I inject the frontalis close to the hairline. In order to reduce the risk of these unwanted effects, injections should be administered in the upper third of the forehead only. The needle should be inserted at a 45° angle superiorly. Because the frontalis is an elevator muscle, weakening can cause brow ptosis or exacerbate preexisting brow ptosis.


There has not been a confirmed serious case of spread of toxin effect away from the injection site when BOTOX® has been used at the recommended dose to treat chronic migraine, severe underarm sweating, blepharospasm, strabismus, or when BOTOX® Cosmetic has been used at the recommended dose to treat frown lines, crow’s feet lines, and/or forehead lines.
