^^ By chance, is your skin on the dry side, like a fair skinned, freckled skin that doesn’t ‘shine’? Skin that doesn’t hold a lot of moisture can be more reactive to rubbing/irritation, and is worse in the winter when temps are cold and air is dry. For me its wool and only in winter.
** disclaimer ** this is based on online research I did trying to figure out a rash I was getting, only in the winter. I’m not a doctor, nor did I see a doctor. But as soon as I stopped wearing wool sweaters it went away. My rash was where the wool was rubbing: inside elbows and neckline. (I was wearing them everyday as my comfy clothes after work.) Once fully healed my skin was more tolerant, but I can’t overdo it.
SO… if this is the case then you would want to keep your skin as hydrated as possible. Mineral oil after the shower while skin is wet, pat skin dry (don’t rub), moisturize after that.
