Thank you for your question and for sharing your photographs brii411. 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.
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.
Despite having a natural appearance when performed correctly, many people are afraid of the results of their Botox treatment, in particular before their first treatment, which is natural. In these cases, a lower dose can be used. For example, sometimes I use 10 units in the glabella region instead of the recommended 20 units. In these cases, I advise my patients that the full results will be seen approximately two weeks after the treatment and have them return at that time to take after photographs. At this point, more Botox can be added if further enhancement is desired. I find that when lower doses are used, patients do not enjoy their results for as long; six to eight weeks as compared to three to four months. Therefore maintenance treatments must be performed more frequently.
A common misconception is that Botox is only for those who are in their 60's or 70's. On the contrary, I have a lot of patients in their 20's who receive Botox. This is either for prevention or for those who have expressive faces. I find that the younger one is when one starts receiving Botox treatments the more signs of aging will be delayed. In other words, Botox can be used to prevent wrinkles from either appearing in the first place or from getting deeper over time.
Botox is a prescription strength medication that is injected into the skin or other areas. Therefore, it is important that the treatment is performed by a trained medical professional. This can be a physician, physician’s assistant, nurse practitioner, or nurse. Laws vary from jurisdiction to jurisdiction on who is allowed to provide the treatment. In California, for example, any of these aforementioned medical professional is permitted to provide a treatment. With the recent explosion of cosmetic medicine, there are more and more people offering such services. This includes core physicians such as plastic surgeons and dermatologists as well as other physicians who are trained in cosmetic treatments such as general physicians, gynecologists, or other specialists. It is important to understand that just because a doctor is a plastic surgeon or dermatologist does not necessarily make them an expert on Botox. General doctors who routinely perform Botox treatments multiple times per day likely have more experience and expertise than a plastic surgeon who spends most of his time performing surgeries and performs perhaps only a single Botox treatment per month. Similarly, there are many outstanding nurse injectors who spend their entire days performing cosmetic treatments, as they are often delegated to nurses. Their experience can at times be great than that of many doctors. This understandably makes it difficult to find a good provider. I recommend looking for experience (specifically in Botox and other minimally invasive cosmetic treatments such as fillers and lasers), before and after photographs, and testimonials. Looking for an office who offers the most competitive price is often a recipe for disaster. We have had many patients come to our office to correct various issues they have had when they selected an injector based on price alone.
If I had a patient who looked like the person in these photographs I would say that a dose of anywhere between 16 and 30 units would be appropriate for the horizontal wrinkles on the forehead and the frown lines. I would also recommend taking a global approach as described above and treating the crow's feet with 6-12 units per side.
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. 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!
