Ringworm is a common fungal infection that affects the skin. It is caused by a group of fungi called dermatophytes. Despite its name, ringworm has nothing to do with worms. The infection forms a ring-like pattern on the skin, often leading to redness, itching, and irritation. It can affect various parts of the body, including the scalp, feet, and groin. To get rid of ringworm, it is important to understand what works to treat it. In this article, we will explore what kills ringworm on the skin and the methods to effectively treat this infection.
What is Ringworm?
Ringworm is a superficial fungal infection that targets the outer layer of the skin. It thrives in warm and moist environments. The fungi spread through direct skin contact with an infected person or animal, or by touching contaminated objects like towels, clothing, or combs.
Ringworm on the skin typically causes circular patches that may be scaly, red, or inflamed. It can appear anywhere on the body but is most commonly found on the feet (athlete’s foot), in the groin area (jock itch), and on the scalp. It is highly contagious, which is why it is important to treat it as soon as it is detected.
How Does Ringworm Spread?
Ringworm spreads from person to person, animal to person, or by coming into contact with contaminated surfaces. Common ways the infection spreads include:
- Sharing personal items like towels, brushes, and combs.
- Direct skin contact with an infected person or animal.
- Walking barefoot in areas like public showers, swimming pools, or locker rooms.
Ringworm can spread quickly, especially in communal or public spaces. Therefore, preventing the spread is just as important as treating the infection.
Symptoms of Ringworm on Skin
Before diving into treatments, it’s important to recognize the signs of ringworm so you can take action early. Symptoms include:
- Red, circular, or ring-shaped rashes with raised edges.
- Scaly or flaky skin.
- Itching, especially around the edges of the rash.
- Skin peeling or cracking in the affected area.
- In some cases, blisters or pustules may appear.
If you notice these symptoms, it is important to start treatment as soon as possible to avoid the infection spreading or becoming more severe.
What Kills Ringworm on Skin?
To effectively kill ringworm on the skin, several treatment methods are available. The goal is to stop the growth of the fungi and to relieve symptoms like itching and discomfort. There are both over-the-counter (OTC) options and prescription treatments that are highly effective against ringworm.
Over-the-Counter Antifungal Creams and Ointments
One of the most common treatments for ringworm is antifungal creams and ointments. These products are available over the counter and can be applied directly to the affected area. Common antifungal medications include:
- Clotrimazole (Lotrimin)
- Miconazole (Monistat)
- Terbinafine (Lamisil)
- Tolnaftate (Tinactin)
These antifungal creams are effective because they contain ingredients that stop the growth of the fungi causing the infection. The active ingredients in these creams work by disrupting the cell membranes of the fungi, preventing them from reproducing.
To use antifungal creams or ointments:
- Clean and dry the affected area before applying the cream.
- Apply a thin layer of the medication to the rash and the surrounding skin.
- Follow the instructions on the product packaging for the recommended application frequency, usually once or twice a day.
Most treatments should be continued for 2-4 weeks, even if the rash appears to improve before then. This helps ensure the infection is fully eradicated and prevents it from coming back.
Antifungal Powders and Sprays
In addition to creams and ointments, antifungal powders and sprays can be used to treat ringworm. These products are especially helpful in areas where moisture is a concern, such as the feet or groin. Powders can help keep the area dry, which is important for stopping the fungi from thriving.
Common antifungal powders and sprays include:
- Zeasorb (Miconazole powder)
- Lotrimin AF powder spray
- Lamisil spray
These products can be sprayed or dusted on the affected area, often once or twice a day. Like creams, powders and sprays should be used for a few weeks to ensure the infection is completely gone.
Prescription Antifungal Medications
If over-the-counter treatments do not work or if the infection is severe, a doctor may prescribe oral antifungal medications. These medications are taken by mouth and help to kill the fungi from the inside out. Some common prescription antifungals include:
- Griseofulvin
- Terbinafine (Lamisil oral)
- Itraconazole (Sporanox)
Prescription antifungal pills are typically used for more persistent or widespread infections. They may be taken for a few weeks or months, depending on the severity of the infection. These medications work by disrupting the fungal cell membranes and preventing the fungi from spreading.
It is important to follow your doctor’s instructions when using prescription antifungals and to finish the entire course of treatment, even if symptoms improve early.
Natural Remedies for Ringworm
In addition to traditional medications, there are several natural remedies that people have used to treat ringworm. While these may not be as effective as medical treatments, some individuals find them helpful in managing symptoms. Here are a few natural remedies:
Tea tree oil: Known for its antifungal properties, tea tree oil can be applied directly to the affected area. Dilute it with a carrier oil like coconut oil to avoid skin irritation.
Apple cider vinegar: Its acidic nature may help to kill fungi. Applying diluted apple cider vinegar with a cotton ball can help soothe the affected area.
Garlic: Garlic has antifungal properties and can be crushed and applied to the skin. Be cautious, as garlic may cause irritation in some individuals.
Coconut oil: Coconut oil contains lauric acid, which has antifungal properties. It can be applied to the affected area to help soothe and heal the skin.
While these natural remedies may provide relief, they should not replace prescribed antifungal treatments. It is best to use them in combination with other treatments for optimal results.
Preventing Ringworm on Skin
Once you have treated ringworm, it’s important to take steps to prevent it from coming back or spreading to others. Here are some tips for preventing ringworm:
Keep your skin clean and dry: Fungi thrive in moist environments, so it’s essential to keep affected areas dry and clean.
Avoid sharing personal items: Do not share towels, clothes, or combs with others.
Wear breathable clothing: Wearing loose-fitting clothing made of natural fibers can help reduce moisture buildup.
Practice good hygiene: Wash your hands regularly and shower after activities like exercising or swimming in public pools.
Treat pets: If your pet has ringworm, make sure to treat them to prevent reinfection.
By following these preventive measures, you can help avoid getting ringworm in the future.
Conclusion
Ringworm on the skin is a common but treatable condition. By using over-the-counter antifungal creams, powders, and sprays, or in more severe cases, prescription antifungal medications, most cases of ringworm can be effectively treated. Natural remedies can provide some relief, but they should not be relied upon as the sole treatment.
If you have ringworm, it is important to start treatment as soon as possible to prevent the infection from spreading. By practicing good hygiene and following the proper treatment plan, you can get rid of ringworm and prevent future infections. Always consult a healthcare professional if the infection does not improve or if you have concerns about your treatment.
