Amoxicillin (or Penicillins in general) belong to a group of antibiotics called beta-lactams which you will want to avoid given your severe allergy history. However Botox and Hyaluronic acid type fillers are not antibiotics or related to amoxicillin/penicillin and are generally well tolerated. I hope you find a good provider and enjoy your outcome!
If you had your forehead AND crows feet treated then the injector should be supplying adequate Botox for the frontal forehead area, glabella (between eye area) and crows feet. Every patient needs an individual evaluation and recommendation, however 54 units for all of this sounds very reasonable.
Allergic reactions to Botox are extremely rare. While possible, it is far more likely one of the new exfoliator/skin products contained a chemical exposure that caused your reaction. I am curious what timeframe the exfoliator was used in relation to receiving the Botox, and how soon after either the symptoms began. I hope you are feeling better!
Although uncommon and generally avoidable ptosis can occur when Botox is placed or migrates to the incorrect muscle near the upper outer orbital rim (same can occur with Xeomin or Dysport). Ptosis generally lasts 3-6 weeks (not as long as the actual Botox lasts). Iopidine drops can be prescribed to reduce the effects of ptosis until it resolves. Good luck and sorry to hear this happened!
