When I got Botox in between my eye brows I get 20 units and get little surface bubbles. Is this from too high of a dose?

Hi there, It is normal to have raised bumps immediately after receiving Botox, as fluid is being injected into an area where the skin in quite thin. The bumps should resolve within 30-60 minutes. However, if these bumps or bubbles are appearing days after being injected, this is not normal and I would suggest that you follow up with your care provider. The results of Botox should last 3-4 months. It may be that the dose you are receiving is not large enough, however it is difficult for me to say if this is true without assessing you in person. 

It's normal to see red raised bumps after Botox as teh injections are often superficial but I don't ever see bubbles with fluid.  Regardless of what it appears like, surface bumps after Botox should be gone in hours. If true blisters, and if persistent, see your doctor.The information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.  The information provided should not be relied upon as a substitute for consultations with a qualified health professional who may be familiar with your individual medical needs. 

Little bubbles aren’t a very common reaction after Botox. Botox typically lasts about four months; however, there are several reasons that it may not last as long, such as product dilution or you just need more filler.  I recommend a formal consultation with a reputable and experienced cosmetic dermatologist to help you get the results you want.

It is hard to give an opinion without more information. You can have little bumps immediately after injection. They should resolve in under an hour. Anything beyond that please speak to your treating physician. Good luck.

The typical botox horns are more the edema after local infiltration of both the procures and corrugatoris; did you mean this? Because, blistering is something different that honestly is not comum with a good technique.

It’s common to see a little hump or “bubble” created Botox injections immediately after we inject the medicine. The skin is thin there just like the forehead. Those humps, bumps, or bubbles flattens our within hours. Now if you’re seeing bubbles days after the injections then that’s not normal.

the bubbles /raised area after Botox injection is related to depth of injection....it is common to see around the eyes and forehead. Some patients may require up to 30 or even 40 units between the brows...Slightly higher dose may give you longevity.  Botox usually lasts 3-4 months, in some maybe longer.  It is common to see some redness, swelling at injection site, but resolves very quickly.

Thanks so much for your question
20 units in the glabella area is the standard dose approved by FDA and health Canada 
If the lumps persist more than few days and it is painful you might have infection in the injection site
It is better to be checked by your doctor or the injector
I hop this help!

It is not unusual to see a “bubble” after Botox treatment to an area (although rare between the eyebrows), and not indicative of too high a dose.
20 units is appropriate for the Glabella region. You can usually expect Botox to last 3-4 months, although some patients may metabolize it quicker.  Increasing your dose may help you have longer lasting results.

Botox is injected into different depths depending on the location. In between the eye and above the medial brow Botox is injected into the muscle. It is common to have some "bubbling" after injection although less common in between the eyes.  On average Botox will last 3 months but for some patients it may be less. Using a higher dose may result in longer lasting results. Good luck!
