Expense has nothing to do with quality of product and quality of shave. No matter what other factors or variables if I use 3 or more blades I will always 100% of the time get bumps and irritation as well as patchy spots. Try less blades. For real, go to your local dollar store and buy the 6 pack of Barbasol branded blades for $1... Just trust me here. These are made by personna and are actually the exact same blades I use except mine are two blade cartridges and these barbasol branded razors are two blade disposables. This will not be an overnight cure though, it will take a few days for your current irritation to clear up. I'm positive you'll be getting close, comfortable, irritation free shaves with these and either way you are only spending a dollar. Get those, some barbasol aloe, and some witch hazel. Best shave of your life for $3
I agree about shaving more often and I too agree with the exfoliating too. I now shave in the shower and receive a much better shave it does seem much faster and feels amazing. I use HeadBlade HeadShed Scrub and it works great!!! I have used before shaving and after as well with great results.
