👉 Armor pimples, also known as dermal papulosis, are small, raised, red bumps or pimples that appear on the skin, often resembling acne scars but typically less severe. They result from the overgrowth of keratinocytes, the cells that make up the outer layer of the skin, and are usually caused by friction, pressure, or irritation. These pimples can be itchy and may become inflamed, but they are generally not painful or contagious. Unlike acne, armor pimples do not involve oil glands and are more common in areas of the body that experience frequent friction or pressure, such as the neck, shoulders, and elbows. They often resolve on their own with time and gentle skincare routines.
