Cheek ptsios 10 days after Botox. I'm 32 and had great fullness. Will my cheeks go back to normal? (photos)

Thank you for your question and for sharing your photographs laumay. 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 pivotal studies used 24 units of Botox (12 units per side) to address the crow’s feet. 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 a deficit under the eyes due to loss of or downward movement of the fat pad in the tear trough area. In some cases, the muscle around the eyes serves to hold up the upper cheek fat pad. If this muscle is relaxed with Botox (as it is when addressing crow's feet), this volume deficit can be exaggerated. In these cases, restoring the lost volume with fillers such as Volbella or Vollure under the eyes or Voluma in the cheeks can correct the deficit.
In the mid face, the zygomaticus muscles sit just below the orbicularis oculi muscle which is treated to address the crow’s feet. When smiling, the zygomaticus muscles pull the corners of the mouth upward. If Botox spreads from the orbicularis oculi muscle downward toward the zygomaticus muscles, these muscles can also become relaxed, leading to the appearance of an asymmetric smile. This side effect resolves on its own in 2 weeks to 4 months, depending on the severity. Some find that laser skin tightening treatments using infrared light or radiofrequency may speed up the resolution process.
Botox and fillers are two dermal (skin-related) products are both very popular for their anti-aging features. Unlike Botox, which relaxes muscles to smoothen out wrinkles associated with facial expression, fillers restore lost volume in various areas of the face and body. Common fillers include the Juvederm family (Juvederm Ultra, Juvederm Ultra Plus, Voluma, Vollure, and Volbella), the Restylane family (Restylane, Restylane Lyft, Restylane Silk, Restylane Refyne, and Restylane Defyne), Belotero, Radiesse, Sculptra, and Bellafill. With age changes occur in the bony structures as well as fat pads, both of which contribute to a youthful appearance. Over time bones move and change shape while fat pads get smaller by losing volume and move downward. Fillers restore such lost volume. Common areas of volume loss include the temples on the sides of the face, the upper cheeks, the tear trough area under the eyes, the nasolabial folds which go from the sides of the nose to the corners of the mouth, the marionette lines which are the continuation of the nasolabial folds to the jawline, the chin, and the jawline. Often times combining fillers with Botox treatments yields superior results.If I had a patient who looked like the person in these photographs I would say that there is an underlying volume deficit which was brought out by the treatment of the crow's feet with Botox. It does not look like the zygomaticus muscles were affected since the corner of the mouth elevates just as well when smiling in the consistent before and after photographs. It appears that the lower portion of the muscle directly under the eye is being used to support the cheek fat. In the after photographs once this muscle is relaxed it is no longer able to support the cheek fat and hence the descent of the fat. A filler such as Voluma or Vollure would be ideal for correction of such a deficit.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!

It is possible that the lower crows feet injection was done too low which could weaken the zygomaticus major muscle.  This can cause your cheek to not elevate fully when you smile. The good news is that the Botox effect will wear off over the next few months. You should go back to see your doctor so he or she can evaluate you in person. Regards,Dr. Ort
