Read the first 7 Vascular & Pigmented Lesion Treatment flashcards as text

  1. A laser technician is treating a patient's rosacea-associated erythema. The ideal endpoint for facial diffuse redness is:

    Answer: Transient mild erythema and edema without purpura

    For diffuse erythema treatment, the goal is sub-purpuric dosing that produces mild erythema and edema without vessel rupture, reducing downtime.

  2. IPL (intense pulsed light) differs from laser in that it:

    Answer: Emits a broad spectrum of light filtered to target ranges

    IPL emits polychromatic light across a broad spectrum (typically 500–1200 nm) and uses cut-off filters to select wavelength ranges appropriate for specific chromophores.

  3. Which post-treatment instruction is most critical after laser treatment of pigmented lesions?

    Answer: Use broad-spectrum SPF 30+ sunscreen and minimize UV exposure

    Sun avoidance and SPF 30+ sunscreen use are essential post-treatment to prevent UV-triggered PIH and protect newly treated skin.

  4. Which of the following best describes a cherry angioma and its typical laser treatment response?

    Answer: A benign capillary proliferation that responds well to KTP or PDL

    Cherry angiomas are benign capillary lesions that respond excellently to KTP (532 nm) or pulsed dye laser targeting oxyhemoglobin.

  5. Test spots are most important when treating which patient scenario?

    Answer: A darker-skinned patient with multiple lentigines being treated for the first time

    Test spots are critical for new patients with higher Fitzpatrick skin types or multiple pigmented lesions to assess chromophore response and minimize adverse effects.

  6. Which histological finding would MOST suggest a lesion requires biopsy before laser treatment rather than proceeding directly?

    Answer: Irregular borders, multiple colors, and rapid recent growth

    Atypical features such as irregular borders, multiple colors, and rapid growth suggest possible malignancy, requiring biopsy before any laser treatment.

  7. When increasing spot size during vascular lesion treatment with the same fluence, which effect occurs?

    Answer: Increased effective penetration depth due to reduced scatter

    Larger spot sizes reduce the proportion of scattered photons at the edges, increasing the effective depth of laser penetration into tissue.
