Keep your nails trimmed to avoid snags and nail injuries, which are common causes of psoriasis flare-ups.

• Soak your nails before trimming them.
• Trim your nails short and file the edge smooth to avoid injuring them or scratching yourself. Avoid excessive cleaning under the nail, because it may promote psoriasis scale buildup.
• Don't cut, tear, or bite the skin around your nails (cuticles).
• Use colorless nail polish to protect your nails.
