Having Noticed A Two Inch Round ,dry Skin Patch On Buttocks

I canoed 117 miles last week and developed a round, dry, elephant skin type patch on both butt cheeks. Both about two inches in diameter. They don't itch but I wonder what I could put on them to get back to a normal skin. I put some cocoa butter lotion on and it burned just a bit. I'm sure it's from the friction between my skin, shorts and the canoe seat...got sore enough to try body glide but too late I'm afraid. Maybe it's just a time thing.Thanks for any help. My name is Paula, I'm 59 and in good health.
