I posted a while ago about "rediscovering" the Astra SP. My oh my what a smooth shave! I have noticed slight irritation and drying afterwards however since using them. I've tried a lot of different creams, and I know its not brush burn because I'm using a soft Parker badger brush. I've had some boars in the past with no issue as well. I think I'm going to try out my old standby the Personna Med Prep tomorrow. I remember there was some slight tug to it, but maybe it will be easier on my face. We shall see! Which one do you prefer!?
