Final answer:
Toxin is typically administered first, followed by filler in medicine.
Step-by-step explanation:
In medicine, the order in which toxin and filler are administered depends on the specific treatment being performed. However, as a general guideline, toxin is typically administered first, followed by filler. This is because toxin, such as Botulinum toxin, is used to relax muscles and reduce wrinkles, while filler, such as hyaluronic acid, is used to add volume and fill in wrinkles.
For example, in facial rejuvenation procedures, toxin would be injected into targeted muscles to relax them and reduce the appearance of wrinkles caused by muscle contractions. After the toxin has taken effect, filler can then be injected into areas that require additional volume, such as cheekbones or lips.
It is important to note that the specific order may vary depending on the treatment plan developed by the healthcare professional administering the injections and the desired outcome for the patient.
