Skin irritations, such as contact dermatitis or allergic reactions, can lead to red dots. These conditions often occur due to exposure to irritants like chemicals, plants, or certain fabrics. The resulting redness can vary from mild to severe.

Bacterial, viral, or fungal infections can cause red spots on the skin. Conditions like cellulitis, shingles, or ringworm may manifest with redness and discomfort. Timely treatment is crucial to prevent complications.

Petechiae are tiny, red or purple dots that appear when small blood vessels beneath the skin break. They can be a sign of various underlying issues, including platelet disorders, infections, or certain medications.
- Cherry Angiomas
Cherry angiomas are harmless growths made up of small blood vessels. They often appear as bright red dots and become more common with age. While generally benign, they can be removed for cosmetic reasons.
