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.
