Tinea Versicolor – Symptoms and Causes
Overview
Tinea versicolor is a common fungal skin infection caused by an overgrowth of yeast called Malassezia, which is naturally present on the skin.
When this yeast grows out of control, it interferes with the skinโs pigmentation, leading to the development of discolored patches that can appear lighter or darker than the surrounding skin.
Physical Symptoms
- Discolored patches usually appear on the neck, chest, back, arms, and shoulders
- Patches may be lighter or darker than the surrounding skin and become more noticeable after sun exposure, as the yeast prevents the skin from tanning
- Affected skin may feel dry and scaly
- Mild itching, though not always present
Affected Population
- Most common in teenagers and young adults.
- More likely to affect individuals living in warm, humid climates, where the yeast thrives.
Tinea versicolor is not painful or contagious, but the discoloration can cause emotional distress. Diagnosis is typically made through physical examination, and sometimes by taking a skin scraping to confirm the presence of yeast.
Treatment involves antifungal creams, medicated lotions, or shampoos. Even after successful treatment, skin color may take several weeks or months to return to normal, and recurrence is common, especially in warm, humid conditions.
Preventative measures include maintaining good hygiene, keeping the skin clean and dry, and avoiding oily skincare products for those prone to the condition.
