For Breast Augmentation, Should I Discontinue 1% Salicylic Acid Use?

Good question, this topical medication would unlikely interfere with anything and I would be ok with you taking it if you were my patient

It is doubtful that topical salicylic acid would cause any problem.  Check with your surgeon to be sure and follow your surgeon's recommendations.

I suspect your surgeon told you to stop taking aspirin  orally prior to your procedure because of the risk of bleeding.  Topical salicylic acid should not cause blood thinning, but it is best to check with your surgeon regarding any medication you are taking and whether it is okay to continue to use it.
