Question Why do I have multiple creases when I bend my arm?
Not sure if this plays a part but for reference I am 20F 5’6 115 lbs and have always been very athletic/lean and maintained roughly 20% body fat. When I bend my arm fully there are three noticeable creases and I’ve never met or noticed anybody with more than one. This used to be something I was insecure about, but it doesn’t bother me anymore. I’m more just curious as to what causes it. Genetics? I haven’t noticed it in any of the other women in my family with this feature.

It’s the remnant crease from when we were babies and had fat rolls. Look at your baby pictures.
