Why your botox isn’t working and how to make your botox last longer.
Let me start by saying, thank you for asking your cosmetic injector your cosmetic injection questions, not ChatGPT.
As a Naturopathic Doctor serving Vancouver Island and Langley, I’m often asked whether Botox® Cosmetic (and the other neuromodulators I use, like Dysport® or Nuceiva™) last longer with repeated use. My approach to cosmetic injections is always holistic and patient-centered—I don’t believe anyone needs botox, but I appreciate that it’s an option for those who want it. If you decide to explore cosmetic injections, education should be a key part of that decision. Research helps explain why results last differently for different people: some find their treatment fades quickly, others enjoy longer-lasting effects. Your body’s unique biology, the precision of your injector, and even small lifestyle habits all influence how long results will hold.
How long does botox last?
Botox (neuromodulators) temporarily block nerve signals to targeted muscles so that the overlying skin can relax and smooth. These injections typically last three to four months. The American Society of Plastic Surgeons notes that there is variation: for some people the effect is shorter (around two months) while others enjoy results for four to six months, particularly after their second treatment. Stanford Medicine’s cosmetic‑surgery team similarly states that the effects “last three‑four months and may be repeated as often as needed.” My own clinical experience matches these figures—most of my Vancouver Island and Langley patients return every three or four months for a refresh, though I have seen results last up to six months.
Interestingly, the Cleveland Clinic notes that over time, as your facial muscles become accustomed to the neuromodulator, the injections may last a bit longer. Muscles that are repeatedly weakened gradually lose strength, and weaker muscles metabolize the toxin more slowly. However, the data supporting this observation are limited; not everyone will experience longer intervals between appointments.
Why your botox results aren’t lasting
Both research and my own clinical experience point to four key reasons botox can appear to wear off sooner than expected:
- Metabolism and lifestyle. Botox is a protein, and your body will naturally metabolize it over time. People with a fast metabolism, such as athletes and people who are highly physically active, often break down the neurotoxin more quickly. Lifestyle factors can also make a difference. Stress, smoking, excessive sun exposure, and an unbalanced diet can all accelerate the body’s aging process or increase how quickly botox breaks down. This all aligns with what I observe with my own patients. Those who love intense workouts, hot yoga, or saunas often find their botox doesn’t last quite as long.
- Injection technique and dosage. How botox (and other neuromodulators) are injected—and at what dose—makes a big difference in how long your results last. If the dose is too low or placed at the wrong depth, the effect may wear off sooner than expected. Your unique facial anatomy also matters: a very light dose might not fully relax the muscle, while too much can increase the risk of your body developing resistance over time. This is where skill and experience really come in. An experienced injector carefully tailors both dose and placement to your muscles, creating results that look natural and last as long as possible.
- Muscle strength and activity. Some of us have very strong or hyperactive facial muscles. The muscles around the eyes and forehead, for example, are in constant use for expression, which means the effects of botox can wear off more quickly in those areas. This is why both the number of units required and how long results last can vary so much from person to person. In my clinic I often start with a lower dose to understand how your muscles respond and adjust in subsequent sessions.
- Immune response and antibody formation. In rare cases the body develops antibodies that neutralize botulinum toxin type A, a condition known as Botox Resistance. Antibodies bind the neuromodulator before it can act on the nerve, so patients see no change. This tends to occur after extended use or very high cumulative doses. True immunity is very rare—doctors estimate that only about one in 10,000 patients who report poor results have genuine resistance. For most people, suboptimal results are due to the other factors above, not immunity.
What you can do to make your botox last longer
While genetics and metabolism aren’t something you can change, there are plenty of ways to support longer‑lasting results.
1. Choose an experienced injector.
Longevity starts with proper technique. Researching a provider’s reputation, reviewing before‑and‑after photos and confirming their credentials are vital steps for what to look for in an injector. Clear communication and trust in the provider’s judgment are key; you’re not just paying for the product but for their expertise. An injector who understands facial anatomy, listens to your goals and tailors dosage accordingly can help ensure the neurotoxin is placed at the correct depth and dosage for optimal longevity.
2. Follow pre‑ and post‑treatment instructions.
The way you prepare for and care for your skin after injections has a major impact.
- Avoid blood‑thinning medications and supplements. Starting three days before treatment, avoid alcohol, aspirin, NSAIDs and supplements like fish oil and vitamin E to reduce bruising. Smoking should be stopped and I recommend avoiding sunbeds or saunas.
- Stay upright and keep pressure off the area. Don’t lie down for four to six hours after botox and avoid heavy makeup or facial treatments for the first day. Keeping your head elevated prevents product migration.
- Move the muscles gently. Continue to animate and exercise the treated muscles after injections to help the product diffuse naturally.
- Skip strenuous exercise and heat. Avoid high‑intensity workouts, saunas, hot baths and hot yoga for 24 hours to prevent increased blood flow that can diffuse the toxins.
- Hydrate and ice. Ice the area in intervals to minimize swelling and bruising and drink plenty of water to support healing.
Following this before and after care guide for your injections can make a meaningful difference in how long your results last.
3. Maintain a healthy lifestyle.
A healthy lifestyle doesn’t just make you feel better—it helps your neuromodulator last. Avoid smoking and minimize excessive sun exposure, both of which can increase muscle activity and accelerate aging. Chronic stress can speed up metabolism and shorten the neurotoxin’s effect. Nourish your body with a balanced diet; dehydration and poor nutrition affect skin and muscle health. I remind my patients that these habits also support overall wellness and skin quality.
4. Keep up with regular treatments and adjust dosage.
Schedule follow‑ups before your muscles regain full strength. Botox is most effective when maintained with regular appointments; waiting too long may require higher doses and can shorten subsequent results. If your initial dose was conservative and results faded quickly, discuss adjusting the dosage with your injector. Conversely, avoid frequent, high‑dose treatments—over time, repeated large doses are linked to antibody development. In my practice I find that spacing treatments every three to four months and using the minimum effective units helps maintain results while minimizing risks.
5. Consider zinc supplementation (with caution.)
Botulinum toxin is a zinc‑dependent protein; adequate zinc is necessary for it to block neurotransmitter release. Providers sometimes suggest taking zinc with phytase (an enzyme that improves absorption) for a few days before treatment. One small study found that participants who took 50 mg of zinc citrate with 3,000 PU phytase daily for five days saw their neuromodulator results last nearly 30 % longer. Another study on gummy smile treatment reported a long‑term decrease in gingival display with zinc supplementation. However, the evidence is limited and scientists note that data are inconclusive. The National Institutes of Health sets an upper intake limit of 40 mg of zinc per day; doses beyond this should only be used short‑term under medical supervision, as high zinc can cause abdominal pain, vomiting and copper deficiency. If you suspect you’re zinc‑deficient or are interested in supplementation, talk with your family doctor or naturopathic physician before starting.
6. Understand and manage botox resistance.
Although extremely rare, true Botox resistance can occur when the immune system produces antibodies that neutralize the toxin. It usually develops in people who have had injections for many years or who receive high cumulative doses. If your results suddenly disappear completely, consult your injector. Some options include waiting several years for antibodies to decline or switching to Xeomin®, a neuromodulator formulation that lacks accessory proteins and is less likely to provoke an immune response. I offer Dysport® and Nuceiva™ because of their natural results, but patients who suspect resistance may benefit from trying a different brand or spacing treatments further apart. Remember, most cases of “Botox not working” are due to technique or lifestyle factors rather than true immunity.
Why the right cosmetic injector matters
At the end of the day, your injector plays a central role in whether your Botox will last. I often remind new patients (and wrote a full post on this) that not every injector is right for everyone. As a naturopathic doctor, I take a minimalistic approach and encourage subtle, natural results. I inform patients that they don’t need botox but that it can be a tool to enhance confidence. When choosing an injector, look for someone who:
- Has a strong reputation and gallery of before‑and‑after photos.
- Communicates clearly and is readily available to answer questions.
- Is properly licensed and uses their knowledge of facial anatomy to tailor treatments.
- Doesn’t oversell or push unnecessary units.
Your provider should also discuss all four approved brands of neuromodulators. I’ve tried different brands and will take my time to explain why I prefer Dysport®, BOTOX® Cosmetic or Nuceiva™. If you have concerns about longevity or immunity, a knowledgeable practitioner can help you decide whether to switch brands or adjust your regimen.
