Interestingly, while I have to be very careful about what I put on my face after shaving to avoid stinging and irritation, I don't have to be nearly as careful with pre-shave products. I use the regular Proraso Pre-Post shave as a pre-shave prep, rinsing it off before I apply lather, and have no problems.
