Some have posted about the issue of scars from razor cuts and abrasions .... several things have helped me overcome leaving too much on my mug from cuts/abrasion from shaving:

1) Antibiotic ointment immediately after any bleeding is stopped;

then ...

2) Vitamin "E" oil (you can get it in liquid form, or just open a Vitamin E capsule and squeeze the oil out). This is a tried and trusted method from those of us who get a lot of surgeries! It reduces scars, and "Keloids", which is exactly what you will get if you put back that 'flap' of skin and cover it up;

3) Believe it or not, massaging the injured area gently to keep it supple and from forming a hard (Keloidic) ridge. Getting blood to the area actually helps promote healing by providing nourishing oxygen to the new tissue.

Scars may be part and parcel of playing with the straight razors, but they do NOT have to be large, detracting and obvious most times!
