What is this? What should I do? (photos)

The Botox did not cause what appears to be a herpetic outbreak. It is probably coincidental. There is a small possibility that the trauma of receiving an injection into the skin was the trigger for an outbreak. Follow up with your doctor for evaluation and treatment. Good luck.

Looking at your photos, it appears that you may have Herpes viral infection. I would suggest going back quickly to your doctor and being placed on Valtrex. Wash your hand very well if you touch that area so that you do not transfer the infection. You might also want to ask your medical doctor to check you as well.

A virus can cause an eruption such as the one seen in the photograph. Shingles or the reactivation of the chickenpox virus or herpes simplex are common viral skin lesions. To determine the origin, a viral culture can be collected for confirmation if done within 24-48 hours of the eruption. Botox injections do not the directly cause one to develop Shingles or herpes. I would also inquire about fillers being used in the forehead area. Tissue necrosis can also appear like the eruption in the photo.
