It's important to address any unexpected symptoms following cosmetic procedures like Botox and Restylane filler. Numbness in the chin area, particularly if it developed weeks after the treatment and following the resolution of bruising, might not be commonly associated with Botox, as Botox primarily affects muscle activity rather than sensory nerves. However, it's possible that the filler might have affected a nerve or there could be a delayed inflammatory response. Although vascular occlusion typically presents with other symptoms such as discoloration or pain, the feeling of numbness and coldness could still warrant further evaluation. I recommend the following steps: Consult Your Provider: Reach out to the healthcare professional who administered the treatment. They can assess your symptoms more thoroughly and determine if they are related to the procedure. Monitor Symptoms: Keep a detailed log of your symptoms including any changes in sensation, temperature, or appearance of the skin in the affected area. Avoid Additional Treatments: Until you have a clearer understanding of the cause, it's advisable to postpone any further cosmetic treatments. Consider a Neurology Consultation: If symptoms persist, a consultation with a neurologist might be beneficial to rule out any underlying nerve issues. It's always best to err on the side of caution and seek professional guidance to ensure that any potential complications are addressed promptly.
