    Area of Science:

    • Dermatology
    • Cutaneous medicine

    Background:

    • Benign skin lesions are common and can be aesthetically concerning.
    • Various treatments exist, but cryotherapy offers a direct and effective approach.

    Purpose of the Study:

    • To outline the efficacy and safety of cutaneous cryotherapy for common benign skin lesions.
    • To highlight the appropriate techniques and freezing agents used.

    Main Methods:
