  1. The Fitzpatrick skin type classification is most important in laser treatment planning because it predicts risk of?

    Answer: Post-inflammatory hyperpigmentation

    Higher Fitzpatrick skin types (IV–VI) have greater melanin content, placing them at significantly increased risk of post-inflammatory hyperpigmentation after laser procedures.

  2. Fractional laser resurfacing is distinguished from fully ablative resurfacing primarily because it?

    Answer: Treats only a fraction of the total skin surface per session

    Fractional technology creates microscopic treatment zones surrounded by untreated tissue, allowing faster healing and lower risk compared to fully ablative treatments.

  3. The principle of selective photothermolysis requires that laser pulse duration be shorter than?

    Answer: The thermal relaxation time of the target chromophore

    Selective photothermolysis dictates that pulse duration must not exceed the thermal relaxation time of the target so heat is confined to the chromophore and spares surrounding tissue.

  4. Ultherapy (microfocused ultrasound with visualization) achieves its tissue-tightening effect by targeting energy at which anatomical layer?

    Answer: Superficial muscular aponeurotic system (SMAS) at 4.5 mm

    Ultherapy delivers focused ultrasound to the SMAS layer at 4.5 mm depth, mimicking a surgical plane to stimulate collagen remodeling and tissue lifting.

  5. Cryolipolysis (CoolSculpting) reduces subcutaneous fat by inducing?

    Answer: Controlled apoptosis of fat cells through sustained cooling

    Cryolipolysis exploits the selective sensitivity of adipocytes to cold, triggering apoptosis at temperatures that leave overlying skin unharmed.

  6. In non-ablative radiofrequency skin tightening, the primary biological mechanism responsible for clinical improvement is?

    Answer: Collagen denaturation followed by neocollagenesis

    RF energy heats dermal collagen to 60–70°C, causing immediate contraction and stimulating a wound-healing response that generates new collagen over subsequent months.

  7. A patient with Fitzpatrick skin type VI is scheduled for laser hair removal. Which laser wavelength is generally considered safest due to lower melanin absorption and deeper penetration?

    Answer: 1064 nm Nd:YAG

    The 1064 nm Nd:YAG laser has the least melanin absorption of the common hair-removal lasers, reducing epidermal injury risk in darkly pigmented skin.
