What is tinea versicolor?
Tinea versicolor is a common skin condition caused by an overgrowth of yeast that naturally lives on the skin. It can lead to patches that look lighter, darker, or pink compared to the surrounding skin.
This condition develops when yeast on the skin grows out of balance. Several factors can increase the risk, including:
- Hot or humid weather
- Heavy sweating
- Oily skin
- Hormonal changes
- A weakened immune system
- Use of steroid medications
The rash often appears on the chest, back, shoulders, or neck. Although the color changes may be noticeable, the condition is not harmful and cannot spread from person to person.
Symptoms
Tinea versicolor can affect skin color and texture, especially during warm weather or after sun exposure.
Common symptoms include:
- Light, dark, or pink patches on the skin
- Dry or slightly scaly areas
- Mild itching
- Uneven tanning
- Patches that become more noticeable in summer
How is it diagnosed?
Healthcare providers usually diagnose tinea versicolor by examining the skin and reviewing your symptoms. The appearance and location of the patches are often enough to identify the condition.
In some cases, a provider may use a special ultraviolet light called a Wood’s lamp to examine the skin more closely. A small skin scraping may also be checked under a microscope to confirm the presence of yeast.
How is it treated?
Treatment focuses on reducing the excess yeast on the skin and helping prevent future flare-ups. Many people improve with medicated skin products and simple skin care changes.
Treatment options may include:
- Antifungal shampoos or body washes
- Topical antifungal creams
- Prescription oral antifungal medicine for widespread cases
- Preventive treatment during warmer months
Even after the yeast is treated, skin color may take several weeks or months to return to normal. Some people experience recurring episodes, especially in humid climates or during the summer.
To help lower the chance of recurrence, providers may recommend avoiding oily skin products, staying cool and dry when possible, and using preventive medicated washes.
