The most common reason Botox doesn't work is that not enough was administered. Botox isn't a one-size-fits-all treatment and the same dose doesn't work for everyone. Some people may need additional Botox to achieve an effective level of muscle weakness. Botox can also be old, overdiluted, or fake. It's a little-known fact that some people can become resistant to the effects of Botox.
If you still don't get results, then you may be one of those rare people who is “immune to Botox”. Keep a record of your previous treatments with your new provider, including when you last received BOTOX, where the shots were given, and how much you were given. A Botox unit will eventually become ineffective by antibodies, and the forehead muscle will recover quickly. Botox Purified Neurotoxin Complex is a suction-dried form of botulinum toxin type A purified and studied for a variety of conditions associated with excessive muscle activity. Just as some people trust Advil for headaches and others rely on Motrin, some patients do better with Dysport than with BOTOX (and vice versa), even though the two products are very similar.
A provider with experience in both can help you determine if Dysport is a better alternative to BOTOX for you. Botox is not a one-size-fits-all treatment, and the identical dose is not beneficial for everyone. If you are not satisfied with the results of your Botox session after a few weeks, contact your provider. If you have deep lines that are present at rest when you're not using your muscles, you won't be able to get rid of those wrinkles with Botox alone. For deep lines that are visible at rest when you're not using your muscles, Botox won't eliminate those wrinkles.
You've spent a lot of money on Botox injections to get rid of your wrinkles, but you haven't seen results. So why doesn't Botox work on forehead lines? Botox is created from a healthy form of the bacteria that cause botulism, and the patient's body will try to develop drug resistance over time. The exact cause is unknown, but it seems that the immune system produces antibodies against Botox. This is the approach used by many Med Spas that have the cheapest price for Botox to attract customers. Everyone can always try to learn to accept and embrace those little expression lines or try any Botox alternative, such as facial exercises.
