Common Skin Spots: Causes, Treatments, and Expert Tips
Contrary to popular belief, white spots on nails are not usually caused by a vitamin deficiency. The most common cause is trauma from aggressive nail filing or manicuring. Other possible causes include fungal infections, keratin granulations from leaving nail polish on for too long, onycholysis (nail lifting from the nail bed), arsenic poisoning, and underlying health conditions such as kidney disease or liver cirrhosis. Treatment depends on the specific cause, but in most cases, the white spots will resolve on their own over time. If unsure or if other nail issues are present, it is best to consult a dermatologist for evaluation and proper diagnosis.
