I've been noticing, especially today, that stretching the skin, even just by using facial muscles or looking up, etc. isn't helping me get a good shave. I get more irritation and less close, especially under my jaw line. I just shaved, and right now there's a spot I missed, even after doing 3 passes and touch-ups, under my left jawline. The spot is visible, and the interesting thing is that when I look up and expose the neck in the same way as when I shaved and I rub my fingers over that spot, I don't even feel it, but when I look straight and rub my fingers over the spot, I feel the stubble, and I'm pretty sure if I shaved that way I would've gotten it for that reason.
So my theory is that, in some areas especially, if I stretch the skin, the hairs kind of lay down flatter against the skin which makes it harder for the razor to catch, while it glides over skin causing more irritation. When the skin isn't being stretched, the hairs stick out more (which is why I could feel the stubble) and makes it easier for the razor to slice the hairs. Anyone else experience this? For those that have, do you think this holds true for the whole face, or is it something that works differently in every part of the face and neck, meaning you have to know which parts to stretch and which parts not to?
