Too much Botox, or a migration of the injection from the immediate treatment area, can cause problems. Since the injections are created from a formulation of the botulinum toxin, high amounts could potentially result in botulism poison, a toxic and fatal form of food poisoning.
Too much Botox in the forehead muscles can cause the eyebrows to droop, making the upper eyelids look very heavy and hooded. The face may look angry or sad all the time. Too much Botox around the eyes can dramatically affect facial expression. The face is simply frozen.
Is It Safe to Use BOTOX in the Long Term? BOTOX is an FDA-approved, low-risk treatment with a great safety record. If you continue to work with an experienced, credentialed injector, it is unlikely you will experience any negative effects of long-term BOTOX use.
Can I do too much Botox? Theoretically, yes. If you continue to receive treatments every 2-3 months for years on end, the muscle will continue to get weaker and flatter. This may give the appearance that the skin can appear thin and lose.
How many units of Botox are allowed on the forehead? For horizontal forehead lines, practitioners can inject up to 15–30 units of Botox. For “11” lines between the eyes (or glabellar lines), up to 40 units are indicated, with higher doses needed in male patients .
There's a common misconception that Botox makes you look older when it wears off. On the contrary, regular Botox treatments make you look younger even after the neurotoxin wears off.
An average Botox procedure uses about 50 units at a time, with the maximum safe amount being 100 units. Typically, you can expect more Botox units if you want to target more dynamic wrinkles like frown lines, forehead lines, or smile lines.
Typically, the effects of Botox last for up to three to four months. Therefore, the recommended treatment is once every three to four months. Nonetheless, if your facial muscles begin to train themselves to contract less, the period of time for each treatment may be extended longer than three or four months.
Many people worry that if they stop getting BOTOX injections, their wrinkles will come back faster and worse than before. However, this is not the case. If you stop BOTOX injections, your wrinkles will slowly start to come back, but slower than if you had never used BOTOX to begin with.
Sustained Botox injections have been shown to increase collagen production in the skin. Collagen is responsible for maintaining skin elasticity, and it gradually reduces with age. As collagen production decreases, it can lead to dry skin and wrinkles.
Botox toxins are thought to remain active in the body or target area for 4 to 6 months before being metabolized and excreted from the body.
If you want to prevent the earliest fine lines from becoming full-blown wrinkles, preventative Botox can be the solution. Botox is approved for patients who are 18 years and older and most experts agree that patients in their mid to late 20s and early 30s are at a good age for preventative Botox treatment.
The traditional Botox schedule calls for new injections every 3-4 months to treat glabellar lines—the horizontal lines on your forehead. A new study indicates that after two years of treatment, a good result can be achieved with less frequent injections.
And if you're wondering if Botox works if you already have wrinkles, the answer is a resounding YES. In fact, smoothing out facial wrinkles and fine lines, like laugh lines, crow's feet, frown lines, etc., is the primary FDA-approved purpose of Botox injections.
Is Botox safe? Although botulinum toxin is life threatening, small doses — like those used in the application of Botox — are considered safe. In fact, only 36 cases of adverse effects associated with cosmetic use were reported to the Food and Drug Administration (FDA) between 1989 and 2003.
When some people see their wrinkles form again after the rejuvenating effects of Botox wear off, they assume that the treatment made their wrinkles worse. This isn't true at all. In fact, regular Botox use can actually retrain certain muscles to move less, leading to smoother skin with less Botox over time.
Patients must be 18 years or older to be able to get Botox. However, most experts agree that in most cases, patients at a good age for preventative Botox treatment are those in their mid-late 20s and early 30s who are prone to wrinkles.
The short answer to how long you should wait between Botox treatments is anywhere from three to four months for the best results. We recommend scheduling around this time frame, which is when most people begin to notice that their results begin to dissipate.
Between 10 to 50 Units of botox
A forehead botox injection can require between 10 to 50 units needed in the forehead depending on the severity of your wrinkles. Allergan, the manufacturer of Botox suggests the amount of units that's recommended in the “five” sites of the forehead is 4 units.
Crow's Feet – 10 to 12 Botox Units per eye (2 eyes would mean 20 to 24 units) Frown Lines – 20 Botox Units. Forehead lines – 20 Botox Units.
The lethal dose of the Botox preparation for a person of 70 kg is calculated to be 2,500-3,000 units. The recommended dose for large muscles, localized by touch, (e.g. gastrocnemius) is 100-400 units, whereas for cosmetic purposes usually less than 30 units are injected directly into the targeted muscle.
