Based on your description —
• Hands looking very different from the rest of the body
• Extreme dryness
• Brown scaly patches
The most likely cause is hand eczema (dry skin dermatitis).
This usually happens due to:
• Frequent handwashing
• Soap, sanitizers, detergents
• Weather changes
• Hard water
Less commonly, it could be:
• Fungal infection (if one hand is more affected)
• Post-inflammatory pigmentation from chronic dryness
In most cases, this is not serious and is treatable.
Next Steps
1. Start a thick moisturizer (petroleum jelly or ceramide cream)
→ Apply 3–4 times daily, especially after washing hands.
2. Switch to a mild soap (avoid harsh or antiseptic soaps).
3. If there is itching or redness:
• Use a mild steroid cream once daily for 5–7 days (if prescribed).
4. If scaling is mainly on one hand:
• Use an antifungal cream for 2–3 weeks.
If no improvement in 10–14 days, consult a dermatologist.
Health Tips
• Do not wash hands repeatedly without need.
• Always moisturize after handwashing.
• Wear gloves while using detergents.
• Avoid hot water on hands.
• Keep nails short to prevent skin damage.
This condition is common and usually improves with proper skin care and treatment.
