How Long After Botox Can Full Effects Be Seen?

I was told that after receiving Botox, you have to wait at least 2 to 3 days just to start seeing any effects. Is this true?

Botox Treatment: What to Expect

Botox starts to work very quickly but the cosmetic effect takes time.  The full effect comes on gradually over two weeks and it dissipates slowly as well.  This question comes up a great deal when timing Botox for special events.  I always recommend that Botox be injected 1 month prior to the event if possible.  This gives you 2 weeks to get the full effect of the treatment.  If any touch up is necessary, you then have another 2 weeks so it is perfect.

In our experience, most people begin to experience noticeable relaxation of treated areas with 48 hours. However, the full effects are generally realized at the 2 week mark. At this point, the key muscles have responded as well as a nice softening of the fine lines/wrinkles in the skin. Whatever wrinkles/deep lines remain after 2 weeks may be addressed with cosmetic dermal fillers such as Juvederm or Restylane.

It depends on the patient. The average time it takes to see the effects of Botox is 3-5 days, but sometimes it can take up to 14.

You will start to see the effect of BOTOX in 1 to 2 days, with a full effect in around a week.

 The day after having your frown lines injected, it should start to become difficult to frown. The full effect is within 2 weeks. Dose adjustments are routinely given to optimize results.

The peak effects of Botox are seen 14 days after a treatment

Thank you for your question brook607. I understand your concern. Botox is a purified protein used to address wrinkles associated with facial expression. When injected into the skin Botox will relax the muscles and smoothen out the overlying wrinkles. The most common areas of treatment are in the upper face. These include the horizontal lines seen on the upper forehead when one raises the brows, the vertical lines seen between the brows when one frowns (frown lines), and the crow's feet seen around the eyes when one smiles.

The pivotal studies used 20 units of Botox in the glabella area between the brow to address the frown lines. These studies demonstrated that the peak results are seen 14 days after the treatment and most people enjoy their results for 3-4 months. At that point, a maintenance treatment is recommended. While some people start to see results as early as the next day, it can take two weeks for full results so patience is important. We have our patients return two weeks after their treatment to assess their results via photographs. At that time additional units may be added if necessary.

With any injection, there are risks such as pain, bleeding, bruising, redness, swelling, tenderness, and infection. We take special precautions to minimize these risks such as using a painless technique. We also treat bruises with a laser as early as the next day. Bruises usually resolve within two weeks if untreated. After a laser treatment bruises usually resolve in 1-3 days, but may still take two weeks for full resolution.

After a Botox treatment, I recommend that my patients avoid heat exposure, alcohol consumption, and strenuous exercise for 24 hours and not lie down flat for four hours. This is because all of these activities may possibly lead to the movement of the product and consequent side effects such as droopy eyelids as described above. Although there have been no definitive studies shown that these actually occur and some physicians do not provide such aftercare instructions, in the absence of data I err on the side of caution and recommend that my patients avoid such activities.

Botox is what we call a neuromodulator. This means that it controls nerves to relax the muscles by preventing them from contracting. Botox is the most popular neuromodulator available, has been the most studied, and is cleared for the most number of indications. Other neuromodulators available in the United States include Dysport, Xeomin, and Mybloc. Overseas many others are also available. Each product has slight differences, but all of them work. The majority of our patients find that they like the results of Botox the best. Additionally, Allergan, the maker of Botox, offers the Brilliant Distinctions Program. This is a rewards program where patients receive points from their Botox treatments which can be used toward discounts at subsequent treatments. Points are also received when patients purchase other treatments in the Allergan portfolio including Juvederm Ultra, Juvederm Ultra Plus, Voluma, Volbella, Vollure, and Kybella or products such as Latisse or Skin Medica products.

I find that combining Botox with other treatments or skin care regimens enhances the results and allows patients to enjoy their results for longer. One specific topical product our patients have found to be outstanding in conjunction with a Botox (and filler) treatment is our Hydrating Serum, which contains hyaluronic acid. Hyaluronic acid draws water into the skin and helps to fill in fine lines and wrinkles.

Please consult with a doctor for specific recommendations. Good luck!

You should expect to see results in three to four days, but in as few as two and as many as five days. On average patients return every three to six months for additional treatments. Good luck.

How Long Does Botox Take

Yes. You will be able to start seeing results of Botox 2-3 days after injection. It can take 7-14 days to see maximum results.

Botox results are usually seen within 2 to 5 days

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
Each individual patient will be different, but generally, most people will begin to see results within two to five days, with full results appearing in one to two weeks. These results then usually last anywhere from 3 to 6 months, depending on the injection location, injector technique, and individual metabolism.

The time it takes to see the full effect for Botox to work can vary from patient to patient. Some patients see a result in 24 hours, some take 2-4 days, some a week or longer.

How Long After Botox Can Full Effects Be Seen?

Hello! Thank you for your question! Typically, one will begin to see effects within 2-3 days. Usually, full effects are seen within a week. If after that time noe effect is seen, consideration for touch-up is reasonable. As a neuromodulator that inhibits reuptake of acetylcholine and the nerve junction, BoTox will continue to work until it wears off at the site. There is no limit to how long one can receive it, but it generally lasts for about 3-4 months on average. Best wishes! Hope that this helps!
