Why Does Botox Stop Working?

Botox is a popular cosmetic treatment that can help reduce the appearance of wrinkles and fine lines. However, there are several reasons why Botox may stop working. The most common reason is that it wasn't given in the right dose. Some people may need additional Botox to achieve an effective level of muscle weakness.

Additionally, Botox can be old, overdiluted, or fake, and its effects may diminish if it's not used within a specific period of time. It's also possible for some people to become resistant to the effects of Botox over time. Finally, the body can develop antibodies and make Botox ineffective. Botox results typically last between two and six months, with average results lasting about three to four months.

This is because the body produces new neurotransmitters all the time, so the “blocking” effect of Botox gradually disappears as these chemicals begin to circulate again in the body. Muscles are no longer inhibited. In rare cases, some people may be completely immune to the effects of Botox. This is why it's important to find a high-volume injector who can give you the right dose and ensure that you're getting a quality product.

Additionally, 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. According to those who recognize the phenomenon of Botox resistance, the numbers are low: about 1% to 3% of patients receiving the injection will develop toxin-blocking antibodies. If you're one of those people who is “immune to Botox”, there are other treatments available such as Xeomin that may work better for you.
