Most people with ringworm of cats do not leave scars, but when they do, the scars are usually permanent, so it is important to treat them properly and promptly. Tinea corporis occurs when the causative fungus of tinea versicolor is transmitted to humans. These causative fungi are usually in the stratum corneum of the skin and do not damage the dermis, so most patients will not be left with scarring. Scarring may occur if the infection is not treated effectively, if the skin lesions continue to worsen, or if infections occur during the healing process due to poor care. Once the scar is formed, it cannot be completely eliminated, but it can be improved through medication, photoelectricity and other treatments. Therefore, when catarrh occurs, it is important to actively treat it and use medication under the guidance of a regular dermatologist to get effective treatment in a short period of time.
