I have sensitive skin, but not as bad as your skin it would appear. The best advice for me was from mantic59 on youtube: never go over the same spot twice in a row, just once nice stroke and move on to the next spot. Think of it as beard reduction passes. Heard it from him, not sure who said it first

Since switching to the straight and/or DE I have reduced my number of ingrown hairs so much that I can't remember the last time I had one.

Good luck!
