Tinea versicolor is a common fungal skin infection that usually appears as light or dark patches on the shoulders, chest, or back, especially in hot weather or if there is more sweating. It happens when a normal skin yeast grows more than usual and affects skin colour, which is why the patches can look uneven or slightly scaly. Treatment usually works best with regular use of antifungal creams or washes containing ingredients like ketoconazole or selenium sulfide. These help reduce the yeast on the skin and slowly allow the colour to normalise, although the colour change may take a few weeks to settle, even after the infection is controlled. Keeping the skin clean, dry, and avoiding excessive sweating or tight clothing can help prevent it from coming back. Sometimes doctors may suggest oral antifungal medicines if the patches are widespread or not improving with creams alone, but that decision depends on examination. It is also important to avoid oily lotions on affected areas, as they can sometimes worsen fungal growth. If the patches keep recurring or spreading despite treatment, a dermatologist review is needed to confirm the diagnosis and adjust therapy for better control.

White patches from tinea versicolor usually happen when a yeast on the skin grows more than normal, especially in hot weather, sweating, oily skin, or when the skin stays damp for long periods. The good thing is the infection itself is treatable, but the colour difference on the skin can take longer to return, even after the fungus is gone, which is why it often feels like it is not improving quickly. A simple routine helps most. Keeping the skin clean and dry is important, so showering after sweating and wearing loose cotton clothes can reduce flare-ups. Medicated antifungal shampoos or washes are often used on affected areas for a few minutes before rinsing, as they help reduce yeast on the skin. Antifungal creams are also commonly used for a few weeks, depending on severity. Avoid oily or heavy skin products on the affected areas because they can worsen the condition. Once the infection is controlled, the patches may still look lighter for some time, but they gradually even out. If the patches are spreading or not improving despite care, a dermatologist should confirm the diagnosis and adjust treatment to prevent recurrence.
