Common causes of white spots in summer
1. Tinea (pityriasis) versicolor
A very common fungal/yeast-related skin condition. It can cause small pale, white, pink, or brown patches, often on the chest, back, shoulders, or neck. They may become more obvious after sun exposure because the affected areas don’t tan normally. Mild scaling can sometimes be seen.
2. Sun-related hypopigmentation
Some people develop small, pale spots after repeated sun exposure, particularly on the arms and legs. These are generally harmless and become more noticeable when surrounding skin tans.
3. Vitiligo
Vitiligo causes sharply defined patches where pigment is lost. The patches can gradually enlarge, and they may occur on the face, hands, around the mouth or eyes, or elsewhere on the body. A dermatologist can usually distinguish it from other causes.
4. Dry skin or eczema-related changes
Inflammation or irritation can temporarily leave lighter areas after the skin heals.
What can you do?
- Use broad-spectrum SPF 30+ sunscreen and reapply when outdoors.
- Don’t try to bleach, scrub, or aggressively exfoliate the spots.
- If the patches are scaly or appear on the trunk, a dermatologist may recommend an antifungal treatment if tinea versicolor is confirmed.
- If the patches are completely white, sharply defined, spreading, or appearing around the eyes, mouth, or fingers, arrange a dermatology examination.
- Remember that even after successful treatment of tinea versicolor, normal skin color can take weeks or months to return.
