How long will 1-2 units of Botox last on each DAO?

Thank you for your question. Botox usually lasts 3-4 months. Always see a board certified plastic surgeon or dermatologist. Regards, 

Typically this lasts 2-3 months.  I suggest you see an expert for an evaluation and treatment.  Best, Dr. Emer.

The effect of Botox typically lasts 3-4 months, regardless of the area that it is injected into. The effect can vary however, and in some people it will last two months, or up to six months in others.

Botox and other neuromodulator injections lasts 3-4 months on average, regardless of the site of injection or amount injected. Everyone is different so the overall range can be as short as 8 weeks to over 6 months. The good thing is that the duration is typically the same for different sites for each individual, so you can schedule your injections at regular intervals. I recommend seeing a trained injector who keeps careful records of your injections including the dates, location, and dose. Even with the most commonly performed cosmetic procedure, first or 20th injection, it's important to make safety a priority.  

Botox will last usually 3-4 months and is not dependent on dose. if you received a good result then that dose was proper and you should expect this length of time

Regardless of number of units used, the Botox that is injected is expected to last 3-4 months. If you are satisfied with the results of the 1-2 units, then it is reasonable that you may need reinjection in 10-12 weeks.

One to Two units in the DAO should last about three to four months- that is the average in any area injected. The other area should last the same amount of time.  Best, Dr. Green

Typically 6-12 weeks depending upon your metabolism of the product. Every patient is different in this regard. 

Botox will last 3 to 4 months no matter where it is placed or how much is placed.  I hope that helps.Best regards.
