White Spots

What are White Spots on Skin?

White spots are areas of skin that appear lighter than the surrounding skin. They can occur anywhere on the body and may be temporary or persistent. Causes range from minor skin changes to underlying medical conditions.

Causes

Common Skin Conditions

• Pityriasis alba – mild, scaly patches often in children
• Vitiligo – loss of skin pigment due to autoimmune causes
• Tinea versicolor – fungal infection causing lighter or darker patches
• Idiopathic guttate hypomelanosis – small white spots, usually from ageing or sun exposure

Other Factors

• Post-inflammatory hypopigmentation – after acne, eczema, or injury
• Sun damage – uneven skin pigmentation
• Nutritional deficiencies – e.g., vitamin B12 or calcium deficiency (rare)
• Genetic conditions – rare inherited disorders affecting pigmentation

Symptoms / Appearance

• Small to medium white or lighter patches on skin
• Usually painless and non-itchy
• Can appear on face, arms, legs, torso, or scalp
• May have slight scaling if fungal
• Sometimes gradually increase in number or size

• Avoid harsh chemicals or over-exfoliation that may damage skin

FAQs

Q1. Are white spots dangerous?
Most are harmless, but some (like vitiligo) require medical evaluation for management.

Q2. Can white spots be permanent?
Depends on cause: tinea versicolor is usually temporary, but vitiligo or age-related spots may be long-lasting.

Q3. How can I tell if a white spot is fungal or autoimmune?
Fungal spots may scale and worsen in warm/humid areas, while autoimmune-related vitiligo is usually smooth, well-defined, and non-scaly.

Q4. Can sun exposure make white spots worse?
Yes – UV can darken surrounding skin, making spots more noticeable.

Q5. Who is most at risk?
People with fair skin, frequent sun exposure, fungal infections, or autoimmune conditions.
