Ok I didn't wait, been fighting allergies so bad I took the trimmers and cut the stache down and finished shaving about an hour ago. I don't know what I did right (wish I knew so I can do it again) but no burn on upper lip and that hasn't been shaved in several years. Still have trouble with irritation on chin, where I have trouble keeping the angle right but I did chicken out on the AS splash and went with balm instead.

Yes Crouton, tell you need a 7 day set, come back and tell us how that is working out
