Introduction
White spots on the skin are a common concern and can appear on the face, hands, arms, or other parts of the body. While some causes are harmless, others may require medical attention. Understanding the reason behind these spots is important for correct treatment.
Common Causes of White Spots on Skin
1. Fungal Infection (Tinea Versicolor)
This is one of the most common causes. It is caused by yeast on the skin that affects pigmentation, leading to light patches.Spots may be slightly itchy and more visible after sun exposure.
2. Vitiligo
Vitiligo is a condition where the skin loses its pigment (melanin), causing white patches.It usually appears gradually and can spread over time.
3. Nutritional Deficiency
Deficiency of vitamins like B12, calcium, or zinc may lead to white patches on the skin.
4. Sun Damage (Idiopathic Guttate Hypomelanosis)
Small white spots can appear due to prolonged sun exposure, especially in older individuals.
5. Pityriasis Alba
Common in children and young adults, this causes light patches, often on the face, associated with dry skin.
6. Post-Inflammatory Hypopigmentation
White spots can develop after skin injury, burns, acne, or infections.
