Query: Works well, but can scratch your skin

I've used this a few times and it does work. The last time I used it I broke out in red splotch marks between my neck and shoulders. I could feel the scratchiness in that area when I was using it. If you have dry or sensitive skin it might be a good idea to use a beard trimmer or one of those smaller battery trimmers if you aren't very hairy just in that area, then use this trimmer everywhere else. I been using hydrocortisone cream 1% and that seems to be taking some of the burn and redness down.
