If you’ve recently noticed small red or flesh-colored bumps appearing on your arms, hands, or fingers, you may be wondering what they are. While they might seem harmless or just a cosmetic concern, doctors warn that certain types of skin conditions should not be ignored — especially when they come with itching, discomfort, or spread over time.
What Are These Tiny Red Dots?
The red dots shown in the image above could be signs of a few different skin issues, such as:
- Dyshidrotic Eczema (Dyshidrosis): Characterized by small, itchy blisters on the hands and feet. These can cause discomfort and may worsen with stress or exposure to allergens.
- Keratosis Pilaris: Often described as “chicken skin,” this condition causes small red or white bumps, usually on the arms or thighs. It’s harmless but can be persistent.
- Petechiae: These are pinpoint red or purple dots caused by tiny broken blood vessels under the skin. They can be a sign of a more serious underlying condition, especially if they appear suddenly and in large numbers.
- Allergic Reaction or Contact Dermatitis: Skin can develop red dots in reaction to allergens or irritants, such as soaps, lotions, or certain fabrics.
