Are there different quality Botox needles?

Yes, needles vary . I doubt that size is the issue because I don't know anyone that uses a needle thicker than a 30G and a bigger needle might also be more likely to drip bigger drips and nobody wants to waste even a drop. However, needle quality varies a lot and there are sharper and duller needles. A needle that came out of same box as another might not even be identical and I sometimes throw one out after one stick when I don't think that it is quite right. Doing many injections with same needle dulls it. If you reconstitute your Botox with saline that is not bacteriostatic, it hurts like the devil.  your Botox

I use a 32 gauge needle which is tiny and is smaller than 30 gauge.  I also use cold air cooling during the injections which helps quite a bit to reduce any discomfort (we call this gentle technique "Kool-Tox").  My patients generally feel minimal discomfort during Botox injections.  If you find that your injections are very uncomfortable, I would suggest trying a different injector.  Regards,Dr. Ort
