Tinea Versicolor: Causes and Symptoms
Everyone has yeast that naturally lives on the skin, and sometimes that yeast can grow out of control and cause a rash. Tinea versicolor, a common rash-causing fungal infection, is an example of this. It is caused by a type of yeast fungus called Pityrosporum ovale and can affect people of any skin color though it is most common in teens and young adults.
A variety of factors can cause Pityrosporum ovale to grow out of control and cause tinea versicolor, including:
- Oily skin
- Hot climates
- Frequent sweating
- Weak immune system
How to tell if you have tinea versicolor:
If you notice a rash on your skin but aren’t sure if it is caused by tinea versicolor, look for these symptoms:
- White, pink, red, or brown patches that are either darker or lighter than the skin around them.
- Spots that do not tan the way the rest of your skin does.
- Spots anywhere on your body.
Diagnosis and Treatment
Tinea versicolor is often diagnosed just by what the rash looks like but can also be diagnosed from a skin sample. Occasionally medical professionals will use an ultraviolet light that makes the affected areas appear a fluorescent yellow-green.
Tinea versicolor can often be treated with over-the-counter antifungal treatments, but sometimes it requires prescription-strength medication. If your symptoms are not responding to over-the-counter treatments or the rash covers large areas of your body, it is time to visit your local FastMed Urgent Care.
