I’m in my teens, and for the past couple of years I’ve noticed these tiny rough bumps on the outsides of my upper arms. They don’t hurt, but sometimes they feel scratchy, especially when I’m wearing tight sleeves. I’ve tried changing soaps, but nothing really changes. It’s more noticeable in colder months, and it makes me a bit self-conscious.
Many people notice improvement over time, especially into adulthood, though the pace varies; ongoing care can help keep the skin feeling smoother.
