Thank you for your question Los Angeles2748. 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 that the information provided here is helpful.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 as you described. 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. 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.Some people have lines at rest (that is without facial expression) which get deeper with facial expression. In these cases, the wrinkles often do not go away completely. However, I find that if patients continue treatments every three months as recommended the wrinkles smoothen out after approximately one year.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. Diffusion of Botox into nearby areas may also be caused by other preventable things. For this reason, I recommend that my patients carefully follow the simple aftercare instructions described below.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.Botox is what we call a neuromodulator. This means that it controls nerves to relax the muscles by preventing them from contracting. Botox is the most popular neuromodulator available, has been the most studied, and is cleared for the most number of indications. Other neuromodulators available in the United States include Dysport, Xeomin, and Mybloc. Overseas many others are also available. Each product has slight differences, but all of them work. The majority of our patients find that they like the results of Botox the best. Additionally, Allergan, the maker of Botox, offers the Brilliant Distinctions Program. This is a rewards program where patients receive points from their Botox treatments which can be used toward discounts at subsequent treatments. Points are also received when patients purchase other treatments in the Allergan portfolio including Juvederm Ultra, Juvederm Ultra Plus, Voluma, Volbella, Vollure, and Kybella or products such as Latisse or Skin Medica products.I find that combining Botox with other treatments or skin care regimens enhances the results and allows patients to enjoy their results for longer. One specific topical product our patients have found to be outstanding in conjunction with a Botox (and filler) treatment is our Hydrating Serum, which contains hyaluronic acid. Hyaluronic acid draws water into the skin and helps to fill in fine lines and wrinkles.Please consult with a doctor for specific recommendations. Good luck!
