Previous Botox was fine, sodium chloride only used. This time I used a new medical professional. After my reaction I discovered she used BSC. I'm severely allergic to ppd. Are the paraben family linked in some way? It's important to know for future reference. I'm being treated for infection and allergy. I'm in day 4 and the swelling has eased in my fitness but has now spread under my eyes. Pictures below show the stages. Thank you
