Thank you for your question sandyrocks. I understand your concern. Botox is a purified protein used to address wrinkles associated with facial expression. When injected into the skin Botox will relax the muscles and smoothen out the overlying wrinkles. The most common areas of treatment are in the upper face. These include the horizontal lines seen on the upper forehead when one raises the brows, the vertical lines seen between the brows when one frowns (frown lines), and the crow's feet seen around the eyes when one smiles.It is difficult to make an assessment without a formal exam in the office where I can view the skin in multiple angles and observe wrinkles formed with facial expression. However, I hope the information provided here is useful.The appearance of frown lines is variable from person to person. Usually they are in a vertical orientation but sometimes they can be oblique and sometimes a horizontal line is seen across the upper portion of the nasal bridge. The most common variation is to have two parallel lines, hence the common term "11's" to describe them. But some people have one, three, or more lines. Some people also will see a bulge in the area when contracting the muscle. This bulge is smoothened out after a Botox treatment.The pivotal studies used 20 units of Botox in the glabella area between the brow to address the frown lines and 20 units of Botox in the forehead area above the brows to address the horizontal lines seen when one raises the brows. These studies demonstrated that the peak results are seen 14 days after the treatment and most people enjoy their results for 3-4 months. At that point, a maintenance treatment is recommended. While some people start to see results as early as the next day, it can take two weeks for full results so patience is important. We have our patients return two weeks after their treatment to assess their results via photographs. At that time additional units may be added if necessary.Although 20 units is a good standard dose to start with in the glabella, some people require a higher dose because of higher muscle volume. This is common in mature patients, in those with large bulges from expressive faces, and in men. I find that Botox still works in these cases, just a higher dose is required. I have used up to 40 units in the glabella.The pivotal studies for the horizontal lines on the upper forehead were published many years after doctors had been using Botox. In these studies, 20 units of Botox were used to treat this area. However, in my experience I find that anywhere from 10 to 20 units works well in this area. For patients with narrow foreheads a lower dose may be used and those with a broad forehead generally require higher doses. I have also found that the full results in this area are seen by two weeks. Therefore, we have our patients return two weeks after their treatment to assess the results via photographs. At that point additional units may be used if further enhancement is desired.When patients present with concerns about specific wrinkles in the upper face such as the frown lines, I always assess and usually treat the other wrinkles in the upper face including the horizontal forehead wrinkles and crow’s feet. The reason is to maintain a harmonious and natural balance to the appearance of the upper face. The muscles in the glabella which are responsible for the formation of the frown lines serve to pull down on the inner brows when a person frowns. Similarly, the muscles around the eyes which are responsible for the formation of the crow’s feet seen when smiling (orbicularis oculi) are also responsible for pulling down on the brows, but in this case the outer brows. On the other hand, the muscle in the upper forehead which is responsible for the formation of the horizontal forehead wrinkles when a person raises the brows (frontalis) serves to pull the brows upward. If one of these muscles is relaxed with Botox and the others are not, the other muscles will still be active. This will lead to an unbalanced and unnatural appearance of the upper face where the brow can be elevated, depressed, or uneven in shape or position. Therefore, I recommend that my patients take a global approach to the upper face when receiving Botox treatments and treat all three of these areas. Sometimes bunny lines on the bridge of the nose are also treated.In addition to addressing various wrinkles, Botox can also be used to adjust the position and shape of the eyebrows. It works the same way as it does when addressing wrinkles, namely by relaxing muscles. In the upper forehead, there are muscles that move the eyebrows up and other muscles that move the eyebrows down. The muscle that moves the eyebrows up is on the upper forehead; this is called the frontalis muscle. It is responsible for the horizontal lines seen on the upper forehead when one raises the eyebrows. The muscles that pull down on the eyebrows are located between the eyebrows and at the corners of the eyebrows. The muscle group between the eyebrows is called the glabellar complex. There is another muscle that goes around the entire eye called the orbicularis oculi muscle. The portion of this muscle under the tail of the eyebrow is responsible for pulling down on the tail of the eyebrow. When any of these muscles is relaxes with Botox the position of the eyebrow can be adjusted. When treating the horizontal lines on the upper forehead seen when one raises the eyebrows, if the dose is too high or if the placement of the product is too low it can lead to the feeling of a heavy eyebrow, difficulty raising the eyebrow, or downward movement of the eyebrow. This can also lead to downward movement of the eyelids, making a person appear tired. It also can make it difficult to apply eye makeup. To correct this Botox is placed in the antagonistic muscles, those in the glabella and orbicularis oculi which pull down on the eyebrows. This will raise the position of the eyebrows. These two areas can be treated with Botox to provide a brow lift. To do so 4-20 units of Botox are used in the glabella between the eyebrows and 2-12 units of Botox per side are used at the tail of the brow and/or the entire crow’s feet region.When Botox is used in the upper forehead, if the dose is too high or the placement is too low it can result in the feeling of heaviness in the eyebrow or even lower the position of the brow. In order to reduce the risk of this possibility, I use a conservative dose in the area and place the product high on the forehead, sometimes near the hair line. Additionally, I recommend that my patients simultaneously receive a small amount Botox between the brows and at the corners of the brows. This will relax the muscles that pull down on the brows to counteract this effect and provide a harmonious balance to the position of the brow. The results are assessed two weeks after the treatment. If there is any asymmetry a small amount of Botox can be placed in the upper face for correction.Sometimes after a Botox treatment a peaked appearance of the eyebrow is seen. This is sometimes called the Spock or Mephisto look, which makes a person appear surprised or sinister. It is also called the Jack Nicholson look, after the appearance of his eyebrows. This can occur if the muscles that pull the eyebrow down are relaxed with Botox. It can also occur if the upper forehead only is treated. In this case the inner portions of the muscles are relaxed preferentially over the outer portions of the muscle. This allows the outer portions of the muscle to pull up on the tail of the eyebrow. While some people desire this appearance, others do not. This effect can be corrected by placing a small amount (1-2 units) of Botox in the upper forehead approximately midway between the eyebrow and the hair line at the peak of the brow. This relaxes the muscle that pulls up on the tail of the eyebrow, thereby restoring a natural appearance.With any injection, there are risks such as pain, bleeding, bruising, redness, swelling, tenderness, and infection. We take special precautions to minimize these risks such as using a painless technique. We also treat bruises with a laser as early as the next day. Bruises usually resolve within two weeks if untreated. After a laser treatment bruises usually resolve in 1-3 days, but may still take two weeks for full resolution. In addition to these risks, with Botox there is also a risk that the product spreads or diffuses to nearby structures. Spread to nearby muscles can lead to side effects such as the temporary appearance of droopy eyelids or a temporary asymmetric smile.After a Botox treatment, I recommend that my patients avoid heat exposure, alcohol consumption, and strenuous exercise for 24 hours and not lie down flat for four hours. This is because all of these activities may possibly lead to the movement of the product and consequent side effects such as droopy eyelids as described above. Although there have been no definitive studies shown that these actually occur and some physicians do not provide such aftercare instructions, in the absence of data I err on the side of caution and recommend that my patients avoid such activities.Please consult with a doctor for specific recommendations. Good luck!
