I have very blemish prone skin. Took me years to figure out my ingrowns were mostly caused by only shaving once every 3-4 days. Now they have almost entirely gone - I would say about an 85% improvement.I've always wondered if that would help. I don't have a problem with ingrowns, but I have always shaved daily or grown a beard.
Same here with my DEs. That said, I shaved on both Wednesday and Thursday, 24-hour beards each, and took off today so that I could do my usual 48-hour beard on Saturday morning before I get my hair cut.Every 2-3 days. The more growth I have the more I enjoy shaving. Particularly with a straight.
