Flat warts are typically treated with topical treatments such as salicylic acid or cryotherapy, which involves freezing the warts. Laser therapy or mild chemical peels may also be used for stubborn warts. In some cases, topical immune-boosting treatments like imiquimod can help stimulate the body’s immune response to fight the virus. Over-the-counter wart removal products may provide some relief but should be used with caution to avoid skin irritation. Consulting a dermatologist is recommended for the most effective and safe treatment options.
