Tinea corporis is a type of fungal skin infection that manifests clinically as an annular erythematous plaque on the trunk, often with a receding middle lesion and a red papular, flaky, itchy margin. After regular treatment, ringworm will fade and the color of the erythematous lesions will become lighter, and the papules and even the flaking on top of the lesions will decrease significantly. In addition, the itching will gradually disappear, so this is the symptom of ringworm fading. Of course, after seeing these conditions during ringworm treatment, it is still recommended that you stick with the treatment for a while longer. Tinea corporis treatment often takes about 20 days or even about 1 month of treatment cycle.
