Ringworm, also known as tinea, is a common fungal infection caused by dermatophytes, fungi that thrive in warm, moist environments. It can affect the skin, hair, or nails. This article clarifies the appearance of ringworm during its healing process, guiding readers on what to expect until full resolution.
Identifying Active Ringworm
Active ringworm presents as a rash on the skin. It appears as a flat, discolored patch, reddish on lighter skin or brown to gray on darker complexions. This patch develops into a ring shape with a raised, scaly border. The center of the ring may appear clear or scaly.
The rash is itchy and can be slightly raised. Rings start small and expand outwards. While the classic ring shape is common on the body, ringworm looks different depending on its location. For example, on the scalp (tinea capitis), it causes itchy, scaly patches and bald spots. On the feet (tinea pedis), it leads to itching, burning, peeling, or cracking skin between the toes or on the soles.
The Healing Process and Healed Appearance
The healing process of ringworm begins as the body’s immune system combats the fungal infection, often aided by antifungal treatments. Initial signs of healing include a gradual reduction in redness, itching, and inflammation. The distinct ring-shaped patches start to fade and become less prominent.
As the infection resolves, the raised border of the rash will flatten, and the lesion’s overall size will diminish. Scaling and flakiness on the skin should also decrease. Fully healed skin returns to its normal color and texture, feeling smooth and no longer itchy or scaly. While scarring is uncommon, temporary discoloration, such as post-inflammatory hyperpigmentation (darkening) or hypopigmentation (lightening), can occur, particularly in individuals with darker skin tones.
Ringworm can take at least two weeks to heal with over-the-counter treatments. More severe infections or those requiring prescription medication may take up to two months. Continue any prescribed treatments even after symptoms subside to ensure complete eradication of the fungus and prevent recurrence. Stopping treatment prematurely can lead to the infection returning and being more difficult to treat.
When to Seek Medical Advice
Consult a healthcare provider if ringworm symptoms do not improve after using over-the-counter antifungal treatments for about two weeks. Seek medical attention if the rash worsens, spreads, or shows signs of a secondary bacterial infection. These signs include increased pain, warmth, pus, or discharge from the affected area.
Ringworm affecting specific areas, such as the scalp (tinea capitis) or nails (tinea unguium/onychomycosis), requires prescription oral antifungal medication, as topical treatments may not be effective. Individuals with a weakened immune system, for example, due to chemotherapy, steroid use, or diabetes, should also seek medical attention for ringworm.
