What is the typical first-line treatment for warts?

The first-line treatment for warts typically involves cryotherapy or topical salicylic acid. Cryotherapy involves freezing the wart with liquid nitrogen, which leads to the destruction of the wart tissue. It is a commonly used procedure due to its effectiveness and the relatively quick results it can provide. Topical salicylic acid works by slowly peeling away the layers of the wart and is often used for more superficial lesions. Both methods are supported by clinical guidelines and demonstrate good efficacy in treating common warts.

Topical retinoids are generally used for acne and certain skin conditions, making them less suitable as a first-line treatment option for warts. Oral antivirals are not indicated for warts, as these lesions are caused by human papillomavirus (HPV), which does not respond to antiviral medications. Moisturizers, while beneficial for maintaining skin hydration, do not treat warts directly and are not considered an appropriate primary treatment. Thus, cryotherapy or topical salicylic acid remains the preferred approach for initial wart management.
