I'm in high school, and have had eczema my entire life. It was on my face, hands and arms when I was younger, but I grew out of it for a while. It only stayed on my arms, in the bend of my elbows, for my whole life. However, for the past year and a half or so, things have been getting worse.
At first, the eczema on my arms got really bad again. As a result, the elasticity there is pretty much obsolete.
