Tiny red dots on the arms can be surprising, but in many cases they’re harmless and temporary. They often appear due to minor irritation, dryness, allergic reactions, clogged pores, insect bites, or sensitivity to soaps, fabrics, or temperature changes. Sometimes, they’re simply small blood vessel changes that become more visible with age, sun exposure, or friction.
However, skin can also reflect internal factors like stress, dehydration, or nutritional imbalances. While there’s usually no cause for alarm, it’s important to monitor changes. If the spots persist, spread, itch, hurt, bleed, or come with other symptoms, seeking medical advice is a smart way to rule out underlying issues and gain peace of mind.
