Tinea corporis skin color?


The doctor would like to ask if, after previously having tinea cruris and being treated with medication for over a month without any itching, the affected skin is now white.
Should I continue applying the medication until the skin completely returns to its original color before stopping the treatment?

Hello: After skin inflammation, it is possible to experience hyperpigmentation or hypopigmentation.
Once there is a change in pigmentation, it usually takes several months to return to the normal skin color.
If the lesions of tinea cruris do not recur, you may stop the medication and try to keep the groin area dry and well-ventilated to prevent reinfection.
Thank you!

When dealing with Tinea Cruris, commonly known as jock itch, it is essential to understand both the treatment process and the implications of skin discoloration following the resolution of the infection. Tinea Cruris is a fungal infection that typically affects the groin area, and while it can be effectively treated with antifungal medications, the skin's appearance may take longer to return to its normal color even after the infection has cleared.

In your case, since you have been applying medication for over a month without any itching or discomfort, it is a positive sign that the infection is likely under control. However, the presence of white patches on the skin can be attributed to several factors, including post-inflammatory hypopigmentation, which is a common occurrence after fungal infections. This condition happens when the skin loses pigment due to inflammation or irritation caused by the infection.

Regarding whether you should continue using the antifungal medication until the skin color returns to normal, it is generally advisable to follow the treatment regimen as prescribed by your healthcare provider. If the medication is specifically an antifungal cream, it is important to continue using it for the full duration recommended, even if symptoms have improved. Stopping treatment prematurely can lead to a recurrence of the infection, as the fungus may still be present in the skin.

Once the infection has been fully treated and you are no longer experiencing symptoms, the discoloration may gradually improve over time. Skin pigmentation can take weeks to months to normalize, depending on individual healing processes and skin types. If the white patches persist for an extended period, it may be beneficial to consult your healthcare provider or a dermatologist for further evaluation. They may recommend treatments such as topical corticosteroids or other therapies to help restore skin color.

In terms of long-term effects, using antifungal medications as directed is generally safe. However, overuse or misuse of topical medications can lead to skin thinning or other side effects. Therefore, it is crucial to adhere to the prescribed treatment plan and communicate any concerns with your healthcare provider.

In summary, continue applying the antifungal medication as directed until the full course is completed, even if the symptoms have resolved. Monitor the skin's appearance, and if discoloration persists or worsens, seek further advice from a dermatologist. Maintaining good skin hygiene and avoiding irritants in the affected area can also help promote healing and prevent future infections.
