Hello Gsdvanleersum,Sjogren's disease is not a contraindication to Botox. I would be careful with injections because it does inhibit the same molecule the saliva glands use to produce saliva. But as long as you aren't treating near the saliva glands then you would likely be fine. I would certainly discuss this with your injector to go over the risks and benefits and decide on a treatment plan. I hope this helps and good luck.
The short answer is yes. Consult a board certified dermatologist or plastic surgeon who is experienced in the use of the material
