Should I be able to move my forhead after botox?

If you are still able to animate then further Botox should help improve your results. You did the right thing by giving it the full two weeks for the final result. At this time you can return to your injector for further treatment, or another expert injector near you.

Thanks for the question and I understand your concern. If you have received adequate Botox treatments in the past, it may be the provider you used for this last treatment wasn’t as experienced and did not inject you with sufficient Botox to achieve your desired result. I would encourage you to find a board-certified cosmetic dermatologist with significant experience using Botox to ensure your treatment is both safe and successful. Experienced injectors know how much Botox to use and precisely where to inject it to produce an optimal outcome.

It sounds as tough you just need more product.  If you are seeing the same injector you could ask if they are using the same dose as they preciously used. I would advise you return to the clinic who performed your treatment and ask them for a top up.  Ensure that the clinic is aware that you would like no movement in your forehead.
Warm Regards,

It sounds like you did not get the appropriate amount of botox since you still have wrinkles in your glabellar region. Some movement of the forehead is desirable, most people don't want the frozen look, but in your case it seems like you are freely moving your forehead, further indication you may have not gotten enough botox. I suggest a second opinion. 

This is not your fault. Results are dependent on the injector, and she may not have injected the appropriate amount of Botox into the areas being treated. I recommend following up with her, and if she is a new injector for you, discuss with her the typical amount of Botox you have received in past treatments, and possibly take your medical records to show her this.  Adding more Botox is an easy fix, but let her know for future reference that you prefer no mobility in your forehead. Hope this helps!

For some patients they prefer some movement of the forehead, most people don't want the frozen look, but in your case it seems like you are freely moving your forehead more that what you would like. Follow up with your injector and explain that you do not want to see any movement to the forehead. It may just be that you need more units to get no movement. Its an easy fix. Hope this helps. 

If you still have movement, you may need more units. You should be getting a total of 30-50 units for the glabella and the forehead with Botox.If you are not getting the results you want from Botox. There are 2 other injection products you can switch to  called Dysport and Xeomin. 

Movement should certainly be reduced in the treatment areas. It maybe that you need a higher dose to get a more complete result.

Thank you for your question Genuine4249. 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 in the absence of consistent photographs before and after in the same lighting and angles for comparison and without knowing the dose used and the exact placement of the product. 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 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.
If I had a patient with the concern described here I would want to see before and after pictures and know the dose and placement of the product. For example, if the dose was too low, additional units can be added for correction. If the product was placed too high on the forehead, additional units can be placed there for correction. I would recommend addressing this concern with the injector again.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!

You should not have a lot of movement in the areas that were injected and 2 units if injected just above the eyebrow will not help and may cause ptosis. you might want to get a second opinion and be sure you are seeing a board certified dermatologist
