I'm guessing the OP, frustrated by the lack of whisker removal, tried to compensate with the use of pressure which resulted in the redness and irritation. A shave ready blade and good stropping will alleviate this to a high degree, but backing the pressure off to zero will go a long way towards a great irritation-free shave.
