Pilarix, opinions and questions

Question to the Pharmacist: Hello, I wanted to ask, and actually seek advice about cosmetics or possibly over-the-counter remedies / in extreme situations with a prescription for use before, during and after shaving intimate areas in an allergic person whose ordinary cosmetics cause skin irritation, redness, in rare situations, maybe extreme causing rashes similar to "urticaria" but smaller, sometimes requiring medical attention. Please any tips on what in the above cases I have to use to say not run to the doctor every few days. I will be grateful for your advice/guidance. Regards, Grzegorz
