    Certain features in a patient's history should immediately raise concern and prompt further investigation or referral.

    These include:

    • Rapid changes in a lesion
    • Bleeding or ulceration
    • Persistent or non-healing areas
    • Lack of a clear cause

    Such features may indicate a more serious underlying condition, including malignancy. In these situations, aesthetic treatment should not be performed until a proper medical evaluation has been completed.

    Recognising red flags early is essential for patient safety and is a key responsibility of any practitioner working with the skin.

    Clinical Takeaway

    When you encounter a red flag, document your findings thoroughly and refer promptly. Never attempt to diagnose or treat suspicious lesions.
