Swollen feet, or edema, can have various causes, including prolonged sitting, pregnancy, high salt intake, injuries, vein problems, and underlying health conditions. Learn about its causes, symptoms, home remedies, and when to seek medical care.
Have you noticed pale or discolored patches showing up on your skin, especially after a day in the sun or a sweaty workout? This can be the sign of tinea versicolor, one of the most common fungal skin conditions worldwide, affecting people of all skin types. Worse, many people don’t go for a medical checkup and mistake it for vitiligo, eczema, or simple sun damage, and end up using the wrong creams for months with zero results. So, in this blog, let’s find out what this condition actually is, and how you can manage it and keep it from coming back.
Tinea versicolor, also called pityriasis versicolor, is a superficial fungal infection. It is caused by an overgrowth of Malassezia which is a type of yeast that normally lives on healthy skin.
The yeast is not something you catch from another person. In certain conditions, it grows excessively and affects the skin’s normal pigmentation, producing patches that may be lighter or darker than the surrounding skin.
Tinea versicolor is not contagious and is not a sign of being unclean.
Tinea versicolor symptoms can vary with skin tone. The patches may be:
They most commonly appear on the upper back, chest, shoulders, neck and upper arms. Several small patches can gradually join together and form larger areas of discolouration.
One easily overlooked clue is what happens after sun exposure. The affected areas do not tan normally, so the contrast between the patches and surrounding skin can become much more evident during summer. This does not necessarily mean the infection has suddenly become worse.
The underlying cause is an overgrowth of Malassezia. Some other factors that can make this more likely are:
Malassezia normally lives on the skin. Problems arise when the yeast multiplies excessively and alters pigmentation and the surface of the skin. Most people who develop tinea versicolor are otherwise healthy.
Warm, humid conditions favour yeast growth. This is why tinea versicolor is particularly common in tropical and subtropical regions and may become more common during hot months.
Malassezia thrives in environments rich in skin oils. Increased oil production, including around puberty, can therefore increase susceptibility.
Changes in hormone levels may alter skin oil production. Pregnancy is one situation in which hormonal changes may increase susceptibility to tinea versicolor.
People with a weakened immune system, or living with some underlying conditions, may be more prone. This does not mean that having tinea versicolor automatically indicates an immune problem.
Patches can understandably raise concern about vitiligo; however the two conditions are different.
| Feature | Tinea Versicolor | Vitiligo |
| Cause | It is caused by the overgrowth of Malassezia yeast. | In this case, the autoimmune condition affects pigment-producing cells. |
| Texture | It usually has fine scaling. | It is smooth, without scaling. |
| Color of patches | May be white, tan, pink, brown, or lighter than surrounding skin | Clearly depigmented, milky-white patches |
| Common areas affected | It commonly affects the chest, back, and shoulders. | Hands, face, and around body openings, among others |
| Treatment | Usually responds to antifungal treatment | Requires different medical management |
These differences can provide clues, but a dermatologist may need to examine the skin to confirm the diagnosis.
A dermatologist (skin specialist doctor) can diagnose tinea versicolor by examining the affected skin.
Depending on the appearance, they may use:
A biopsy is rarely necessary but may be considered when the diagnosis remains uncertain.
Treatment aims to control the yeast overgrowth. The choice depends on how widespread the infection is and whether it keeps returning.
For mild cases, antifungal creams, lotions, washes or shampoos may be sufficient. Some antifungal products are designed to be applied to the skin rather than used only on the scalp. But make sure you are using them as per your dermatologist’s recommendation only.
A dermatologist may prescribe stronger or specific topical antifungal treatment when over-the-counter products are unsuitable or have not worked.
For extensive disease or frequent recurrence, a skin specialist may consider oral antifungal medicines. These medicines are not appropriate for everyone and should not be self-prescribed because they can have drug interactions and other risks.
Note – Killing the yeast does not immediately restore normal skin colour. Pigmentation can take weeks or months to even out, and in some people it can take considerably longer.
Tinea versicolor can return because Malassezia is normally present on the skin. Hygiene cannot permanently remove the yeast, but practical habits can reduce conditions that encourage overgrowth.
There is limited reliable evidence that household remedies such as vinegar, lemon juice or other acidic substances can safely treat tinea versicolor. They may irritate the skin and make discolouration harder to assess. That is why evidence-based antifungal treatment is a safer approach.
You should consider seeing a dermatologist if:
If you have persistent or recurring skin discolouration, a dermatologist at The CK Birla Hospital can help determine whether it is tinea versicolor or another skin condition and guide you towards appropriate treatment. Book a consultation to get expert advice.
