Small red dots that appear on your skin and cause redness when scratched, then fade away, may be due to mild skin irritation or a condition like dermatographism (skin writing), where the skin reacts to scratching with temporary redness and rash-like marks.

🩺 Possible Causes

• Dermatographism: A common, harmless condition where scratching causes raised red lines or dots.
• Allergic reactions or mild eczema: Can cause intermittent redness and itching.
• Dry skin or minor irritation: Leading to temporary redness after scratching.

🏥 What You Should Do

• Keep your skin moisturized with gentle emollients to reduce dryness and irritation.
• Avoid harsh soaps or irritants that may worsen the redness.
• You may try a topical anti-itch lotion containing calamine and light liquid paraffin, which soothes and hydrates the skin.
• If the redness or rash worsens, becomes persistent, or is accompanied by other symptoms like swelling or pain, consult a dermatologist for a thorough evaluation.

⚠️ When to Seek Medical Advice

• If the rash spreads or becomes painful.
• If you develop swelling, blistering, or signs of infection.
• If itching severely affects your daily life or sleep.
