If you’re noticing small white spots appearing all over your skin or body, it’s important to take it seriously and understand what could be happening. Here’s a careful guide:
Possible Causes of White Spots on Skin
- Vitiligo
- Autoimmune condition where melanin-producing cells are destroyed.
- Spots are usually well-defined, depigmented patches, can appear anywhere.
- May spread over time.
- Pityriasis Versicolor (Tinea Versicolor)
- A fungal infection causing small white, pink, or brown patches.
- Often scaly or slightly itchy, usually on chest, back, and arms.
- Idiopathic Guttate Hypomelanosis
- Tiny, round white spots often on arms and legs, especially in sun-exposed areas.
- Common in older adults; harmless and mainly cosmetic.
- Nutritional Deficiencies
- Lack of zinc, calcium, or vitamin D can sometimes cause white spots on skin or nails.
